The 2022 MT Series of Fi subwoofers is designed to meet the needs of the serious competitor and and monster basshead. With a massive 4″ voicecoil for increase thermal capacity, we designed the rest of the motor via FEA to optimize the proprietary US steel (water jet and machined in house at Fi when your order is placed). Using three ultra-high grade Y35 magnets, a flux flow derived back plate geometry, and a solid pole with aluminum sleeve and aluminum compression cap, there is plenty of thermal capacity in the MT Series. Our Fi designed heavy 5 spider pack coupled with our special 144 tinsel count leadwire to keep the moving assembly under control at extreme excursion levels. The reworked surround geometry on the 12″, 15″, and 18″ models optimizes cone area vs excursion yielding the most output vs excursion. The 2022 MT Series is designed for competition use and monster daily driving systems requiring high linearity and extreme power handling. From a punishing low end to the subtle nuances in your favorite reference track, the MT Series delivers!

The MT Series allows for 2 stages of cooling and inductance mitigation.

STAGE 1: Is a machined aluminum pole sleeve that reduces inward coil inductance shift and helps linearize overall inward vs outward inductance reducing distortion. This sleeve also aids in heat wicking to the pole as aluminum has a significantly better thermal coefficient than steel alone does.

STAGE 2: Uses both the pole sleeve and an aluminum pole cap to increase compression and cooling. Also, via its profile and increased aluminum around the coil as it gets closer to the pole itself, inductance is further reduced. As a coil moves inward its inductance increases relative to the steel it surrounds, so the closer the coil is to steel, the more aluminum you would want in proximity to it. As inductance is the natural resistance to directional change, reducing and linearizing it increases output range and can ease some amplifiers operation.

All NEO 3.X Series

New cooling and inductance features that are set up in stages. The first stage is a machined aluminum pole sleeve. This provides better heat wicking and is the first portion of inductance linearizing and reduction. The second stage is a combination of the pole sleeve and an aluminum domed compression cap. This increases the compression ratio for cooling as well as adds some outstroke inductance reduction. The third stage utilizes the pole sleeve, the compression cap, and a thick aluminum finned extrusion that again lowers and linearizes inductance as well as aids in thermal dissipation. With the third stage we have reduced inductance by almost a factor of 3 over utilizing none of the aluminum.

All leads are stitched in the same pattern and use the bolted terminal block as the original hybrid design. But we have added push terminals that use this same setup with the ability to handle much larger wire and completely removing the multiple solder and crimp points that could introduce unwanted resistance.

All Neo3.X subs use the high Xmax dual 1 Ohm and dual 2 Ohm coils for 34mm of one way Xmax.

NEW Option
Need more motor force and efficiency from a lighter package? Opting for Fi Car Audios Black Neo will up your lower line driver to the next series up in motor force, but keep the lighter series weight. Need more motor force for crushing lows and compression fighting in the gap Gauss? Opting for Fi Car Audios Black Neo will take your N3.9 or N4.11 to the next level. Generating more motor force than previously available with the standard high temp Neo, you can gain 10-20% more Gauss without having to go to a simply massive motor.

All NEO 3.X Series

New cooling and inductance features that are set up in stages. The first stage is a machined aluminum pole sleeve. This provides better heat wicking and is the first portion of inductance linearizing and reduction. The second stage is a combination of the pole sleeve and an aluminum domed compression cap. This increases the compression ratio for cooling as well as adds some outstroke inductance reduction. The third stage utilizes the pole sleeve, the compression cap, and a thick aluminum finned extrusion that again lowers and linearizes inductance as well as aids in thermal dissipation. With the third stage we have reduced inductance by almost a factor of 3 over utilizing none of the aluminum.

All leads are stitched in the same pattern and use the bolted terminal block as the original hybrid design. But we have added push terminals that use this same setup with the ability to handle much larger wire and completely removing the multiple solder and crimp points that could introduce unwanted resistance.

All Neo3.X subs use the high Xmax dual 1 Ohm and dual 2 Ohm coils for 34mm of one way Xmax.

NEW Option
Need more motor force and efficiency from a lighter package? Opting for Fi Car Audios Black Neo will up your lower line driver to the next series up in motor force, but keep the lighter series weight. Need more motor force for crushing lows and compression fighting in the gap Gauss? Opting for Fi Car Audios Black Neo will take your N3.9 or N4.11 to the next level. Generating more motor force than previously available with the standard high temp Neo, you can gain 10-20% more Gauss without having to go to a simply massive motor.

From setting world records or just crushing souls with insane output and bottom end performance adding the Fi Car Audio Black Neo to your next subs will up your game for sure

But we have added push terminals that use this same setup with the ability to handle much larger wire and completely removing the multiple solder and crimp points that could introduce unwanted resistance.

All Neo4.X subs use the high Xmax dual 1 Ohm and dual 2 Ohm coils for 33mm of one way Xmax.

New cooling and inductance features that are set up in stages. The first stage is a machined aluminum pole sleeve. This provides better heat wicking and is the first portion of inductance linearizing and reduction. The second stage is a combination of the pole sleeve and an aluminum domed compression cap. This increases the compression ratio for cooling as well as adds some outstroke inductance reduction. The third stage utilizes the pole sleeve, the compression cap, and a thick aluminum finned extrustion that again lowers and linearizes inductance as well as aids in thermal dissipation.

The 2022 MT Series of Fi subwoofers is designed to meet the needs of the serious competitor and and monster basshead. With a massive 4″ voicecoil for increase thermal capacity, we designed the rest of the motor via FEA to optimize the proprietary US steel (water jet and machined in house at Fi when your order is placed). Using three ultra-high grade Y35 magnets, a flux flow derived back plate geometry, and a solid pole with aluminum sleeve and aluminum compression cap, there is plenty of thermal capacity in the MT Series. Our Fi designed heavy 5 spider pack coupled with our special 144 tinsel count leadwire to keep the moving assembly under control at extreme excursion levels. The reworked surround geometry on the 12″, 15″, and 18″ models optimizes cone area vs excursion yielding the most output vs excursion. The 2022 MT Series is designed for competition use and monster daily driving systems requiring high linearity and extreme power handling. From a punishing low end to the subtle nuances in your favorite reference track, the MT Series delivers!

The MT Series allows for 2 stages of cooling and inductance mitigation.

STAGE 1: Is a machined aluminum pole sleeve that reduces inward coil inductance shift and helps linearize overall inward vs outward inductance reducing distortion. This sleeve also aids in heat wicking to the pole as aluminum has a significantly better thermal coefficient than steel alone does.

STAGE 2: Uses both the pole sleeve and an aluminum pole cap to increase compression and cooling. Also, via its profile and increased aluminum around the coil as it gets closer to the pole itself, inductance is further reduced. As a coil moves inward its inductance increases relative to the steel it surrounds, so the closer the coil is to steel, the more aluminum you would want in proximity to it. As inductance is the natural resistance to directional change, reducing and linearizing it increases output range and can ease some amplifiers operation.

Sky High Car Audio BMX Series Subwoofers

Available in 6.5” – 18” | D1/D2 Ohm Options

BMX: Where Output Meets Endurance. 

After years of development, trial and error, and decades immersed in the car audio industry, the BMX Series from Sky High Car Audio has finally arrived—representing the culmination of everything we’ve learned from competing, building, and manufacturing elite-level subwoofers. With deep roots in the basshead community and ownership in some of the most respected brands in the game, we’ve poured all our knowledge into the design and execution of what we believe is a true game-changer. The all-new BMX Series isn’t just a subwoofer—it’s the next evolution in high-performance bass.

At its core, the BMX Series is a high-excursion, true-to-size subwoofer featuring a 3” 8 layer voice coil, rated for 2500W RMS of clean musical power, with the motor and coil combination capable of enduring thermal bursts up to 25,000 watts. This beast utilizes a triple-stacked Y35 ferrite motor structure with aluminum shorting ring, pole vents and (4) drilled and tapped backplate holes, giving builders flexibility for reinforced mounting or enhanced cooling. A tooled SHCA magnet boot completes the structure—adding both functional protection and a sleek aesthetic.

Mechanically, the 12”, 15”, and 18” BMX subwoofers push performance with an impressive 32mm Xmax and 39mm Xmech, delivering massive excursion while maintaining control. The 10” stacked spider pack, spaced for increased durability, keeps everything tight and responsive under heavy load. A fiberglass-reinforced cone support lies beneath a hardened paper cone—engineered with a tooled recess for the standard carbon fiber dust cap, maximizing cone integrity and minimizing flex during peak output. To round out the features we utilize a secondary pressure cap nestled under the primary cap which works as a pressure buffer and structural reinforment to the primary cap.

Connection is no afterthought—4-gauge push terminals ensure serious current delivery, while the foam surround is precision-molded for optimal compliance. Finished in an all-black stealth aesthetic, the BMX Series not only performs like a champion—it looks the part too.

With a low FS and high BL, the BMX Series is designed to play across the entire bass frequency range with authority and musicality. It’s not a one-note wonder—it’s a daily demo monster and a competition weapon rolled into one.

Customization Options: Sky High Car Audio is proud to offer in-house custom build options for select subwoofer lines, hand-assembled at our Sparks, NV facility. Customization is available exclusively on the BMX Series 10–18”, FMX Series 12–18”, and FXXL Series 12–18” models. We offer custom Prismatic Powders powder coating in single-stage or two-stage finishes to match your build’s aesthetic (additional cost and lead time apply). For those looking to stand out in the lanes or the show floor, forged carbon fiber cone upgrades are available on FMX and FXXL subs for a premium finish and added cone rigidity. Builders can choose between direct leads (with length and color options) or push terminals on FMX and FXXL models, which come standard with direct leads. We also offer box support add-ons for our threaded backplates and optional back plate cooling modifications for all eligible series (back plate cooling to drop 1/1/26). Lastly we can build you a custom spider pack to meet your needs, but for daily music we highly suggest the stock build form for suspension.

Sky High Car Audio FMX Series Subwoofers

Available in 6.5” – 18” (excludes 10”)

D1/D2 Ohm Options

FMX: Forged to Perform. Built to Endure.

The FMX Series from Sky High Car Audio is the next evolution of our commitment to high-output, thermally superior yet efficient subwoofers for serious bass enthusiasts. With decades of experience, competitive insight, and

our long standing pursuit of big bass, the FMX Series builds upon our legacy by pushing limits. This isn’t just a bigger sub—it’s a smarter, stronger design for those who demand more from their system.

At the heart of the FMX Series lies a massive 3.5” 8 layer high-temp voice coil, the centerpiece of its performance. This coil not only allows for top-tier excursion of 37mm and xmech at 44mm, but it increases thermal handling by over 50% compared to standard 3” designs—without sacrificing the efficiency that makes Sky High subs musical, responsive, and versatile. The result is a woofer that thrives in high-output builds while staying cool and controlled.

Rated at 3500W RMS, the FMX Series is designed for sustained musical power. A quad-stacked 220mm Y35 ferrite motor generates brutal magnetic force. The motor features also include an aluminum shorting ring, pole vents and (4) drilled and tapped backplate holes, giving builders flexibility for reinforced mounting or enhanced cooling. A full-size 10” progressive spider pack provides long-lasting mechanical control and suspension stability—key for subs built to dig deep and hit hard. To round out the features we utilize a secondary pressure cap nestled under the primary cap which works as a pressure buffer and structural reinforcement to the primary cap.

Aesthetically, the FMX Series is all business. Each woofer features our signature forged carbon fiber dust cap, nested into a tooled recess for added cone strength. A fiberglass-reinforced cone support, precision-molded foam surround, and our tooled SHCA magnet boot complete the package in a clean, all-black finish that matches its serious performance.

Connection points include 4ga push terminals designed to handle real-world current without compromise. Like all SHCA subwoofers, the FMX is designed for low FS and high BL, delivering powerful, wideband bass—not just a single-note boom.

Sky High Car Audio FMX Series Subwoofers

Available in 6.5” – 18” (excludes 10”)

D1/D2 Ohm Options

FMX: Forged to Perform. Built to Endure.

The FMX Series from Sky High Car Audio is the next evolution of our commitment to high-output, thermally superior yet efficient subwoofers for serious bass enthusiasts. With decades of experience, competitive insight, and

our long standing pursuit of big bass, the FMX Series builds upon our legacy by pushing limits. This isn’t just a bigger sub—it’s a smarter, stronger design for those who demand more from their system.

At the heart of the FMX Series lies a massive 3.5” 8 layer high-temp voice coil, the centerpiece of its performance. This coil not only allows for top-tier excursion of 37mm and xmech at 44mm, but it increases thermal handling by over 50% compared to standard 3” designs—without sacrificing the efficiency that makes Sky High subs musical, responsive, and versatile. The result is a woofer that thrives in high-output builds while staying cool and controlled.

Rated at 3500W RMS, the FMX Series is designed for sustained musical power. A quad-stacked 220mm Y35 ferrite motor generates brutal magnetic force. The motor features also include an aluminum shorting ring, pole vents and (4) drilled and tapped backplate holes, giving builders flexibility for reinforced mounting or enhanced cooling. A full-size 10” progressive spider pack provides long-lasting mechanical control and suspension stability—key for subs built to dig deep and hit hard. To round out the features we utilize a secondary pressure cap nestled under the primary cap which works as a pressure buffer and structural reinforcement to the primary cap.

FMX: Forged to Perform. Built to Endure.

The FMX Series from Sky High Car Audio is the result of years of innovation, real-world testing, and deep involvement in the high-output car audio scene. Every aspect of this line reflects our passion for pushing limits—from competition lanes to daily builds. Drawing from decades of experience and leadership in the industry, the FMX lineup represents a smarter, stronger class of subwoofers purpose-built for those who demand reliable performance and lasting thermal stability.

For installs with limited space that still demand serious output, the FMX 6.5” and 8” subwoofers deliver unmatched punch and clarity with class-leading motor force and thermal control in their size class. Built around triple-stacked Y35 ferrite motors and finished with standard forged carbon fiber cones and dust caps, these woofers pack heavyweight power into compact footprints.

The FMX Series 6.5” features a 600W RMS rating, driven by a 2” high-temp coil, and stabilized by a 5.5” progressive spider. It’s equipped with Sky High 10-gauge direct leads, ensuring clean power transfer and reliable long-term use. Despite its small size, the 6.5” FMX hits with control and depth, making it ideal for tight spaces or multi-driver setups where output and efficiency matter.

The FMX Series 8” steps things up with a 2.5” voice coil, 800W RMS power handling, and a precision-tuned 6.5” progressive spider. A rated 16mm Xmax allows serious stroke, while 10-gauge direct leads ensure efficient electrical flow under demanding use. With a larger motor and extended coil, the 8” FMX delivers both high end bass articulation and deep low-end authority in small enclosures.

As with the rest of the FMX family, both models come finished in a stealth black aesthetic, including the forged carbon fiber dust cap recessed into the cone for strength, and a full fiberglass cone support underneath for added rigidity. These subs aren’t just made to look good—they’re built to last and perform.

Like their larger siblings, the 6.5” and 8” FMX offer excellent bandwidth and musical versatility—not just SPL peaks.

Note: No customization options are available on the FMX 6.5” and 8” models. These subs come optimized and ready to perform straight out of the box.

Sky High Car Audio FXXL Series Subwoofers

Available in 12” – 18” | D1/D2 Ohm Options

Our Ferrite Flagship. 

Purpose Built to Punish.

The FXXL Series from Sky High Car Audio is the peak of subwoofer engineering—our no-compromise solution for those who demand maximum output, precision control, and true competition-grade performance. Backed by years of technical experience and hands-on development across multiple high-performance audio brands, the FXXL Series reflects the very best of everything we’ve learned in one elite platform.

At the core of the FXXL Series is a massive 4” 8 layer high-temp voice coil, engineered for power handling and consistent output under extreme demand. Rated at 5000W RMS, this coil provides increased surface area and thermal mass, resulting in cooler operation and significantly more headroom than even our FMX series. The FXXL series bridges the gap between SPL monsters and daily drivability.

Driving that power is a towering quad-stacked 9.96” (253mm) Y35 ferrite motor structure, is packed with features like an aluminum shorting ring, pole vents and (4) drilled and tapped backplate holes, giving builders flexibility for reinforced mounting or enhanced cooling. Our motor design results in maximum airflow and heat dissipation during high-output demos.

Mechanically, the FXXL uses a full 10” progressive spider pack paired with a fiberglass cone support and a hardened paper cone. The cone is tooled with a recessed cavity to seat the standard forged carbon fiber dust cap, increasing structural integrity at peak excursion. The surround is precision-molded foam, delivering control, compliance, and longevity across extreme stroke conditions. To round out the features we utilize a secondary pressure cap nestled under the primary cap which works as a pressure buffer and structural reinforcement to the primary cap.

Aesthetically, the FXXL Series carries the Sky High signature stealth look—all black with a carbon dust cap, tooled SHCA magnet boot, and oversized push terminals to ensure secure, high-current connectivity. Every design detail, from the cone geometry to the airflow path, was made to maximize both performance and reliability.

Engineered with low FS and high BL, the FXXL plays strong across the entire bass frequency spectrum with precision, power, and musicality…is that a word? Anyways…It’s not just about being loud—it’s about being the best at every level.
