Sky High Car Audio FMX Series Subwoofers

 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. 

Box Designs: Sky High Car Audio is proud to partner with Hunter Martin from EZ DB’s, one of the most respected and proven enclosure designers in the industry. We’ll be offering FREE box designs—including ported, 4th order, and 6th order options where applicable—tailored specifically for our subwoofers to ensure maximum performance and reliability. As a bonus, any customer who purchases 4 or more BMX, FMX, or FXXL series subwoofers directly from Sky High Car Audio will receive a $50 credit toward a custom enclosure design from EZ DB’s, giving you a serious head start on a professionally designed, competition-ready subwoofer enclosure. Every SHCA subwoofer is tested using DATS-LA, measured with the backplate off the surface after full break-in, ensuring accurate and trustworthy TS data.

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. 

Welcome to the next tier of performance.

Welcome to the Sky High Car Audio Revolution.

Keeps my sink area neat and organized
Color: Black, Size: Medium
Really happy with this sink caddy! The 304 stainless steel feels sturdy and looks nice, and the auto drain spout keeps water from pooling on the counter. The divided sections easily hold my sponge, brush, and soap bottle without taking up much space. I also like the removable towel bar and that there was no installation needed. Redy to use right out of the box. Simple, practical, and very useful for keeping the sink area tidy.

it is good quality
Color: Black, Size: Medium
this is very sleek and handy. I like how it looks and sits on the counter. One thought the part the holds the dish cloth falls off when I take the dish cloth off. It is a minor issue, however, if there was a way to clip it more secure to the item, this would be ideal. thank yoo

Most importantly, its drainage system directs water into the tank, keeping it dry.
Color: Black, Size: Medium
This drain rack is small and fits perfectly on the edge of my sink. It's just the right size to hold hand soap and dishcloths, doesn't take up much space, and most importantly, it directs water directly into the sink, keeping it dry and keeping my sink clean and tidy.

Good product
Color: Black, Size: Medium
It is as described, looks neat and tidy on the sink. Just big enough to do what I need it to do. My sink stays dry because the wate goes back int the sink.
