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, theFMX 6.5” and 8” subwoofersdeliver unmatched punch and clarity with class-leading motor force and thermal control in their size class. Built aroundtriple-stacked Y35 ferrite motorsand finished withstandard forged carbon fiber cones and dust caps, these woofers pack heavyweight power into compact footprints.
TheFMX Series 6.5”features a600W RMS rating, driven by a2” high-temp coil, and stabilized by a5.5” progressive spider. It’s equipped withSky 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.
TheFMX Series 8”steps things up with a2.5” voice coil,800W RMS power handling, and a precision-tuned6.5” progressive spider. A rated16mm Xmaxallows serious stroke, while10-gauge direct leadsensure 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 astealth black aesthetic, including theforged carbon fiber dust cap recessed into the cone for strength, and a fullfiberglass cone supportunderneath 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.
