Sold by AudioSellerz.com

The Sky High Car Audio FE Slim Series 8" Subwoofer (FE-8SL) is a true shallow-mount bass solution for builders who are tight on space but still want real low-end performance. With only 2.95" mounting depth and a 2" dual voice coil rated at 200 watts RMS, this 8 inch FE-SL is perfect for trucks, standard cab pickups, behind-seat boxes, under-seat enclosures, and stealth systems where most subs simply won’t fit.

Built around an underhung ferrite motor with a 30oz magnet, the FE-8SL is designed for tight, controlled bass and efficient performance on modest power. A 5.7" (145mm) spider and 8.5mm Xmax (one-way) give it enough stroke to move real air while staying in control, making it a great match for daily driver systems, entry-level amps, and budget-friendly builds that still want solid output and musical sound.

Like the rest of the FE-SL family, the FE-8SL uses an all-new tooled shallow basket designed specifically for low-depth installs. The surround, cone, motor, and suspension are all tuned to work together in small enclosures, giving you usable bass in places that normally only get “mid-bass” or rattles. Sky High engineered this line from the ground up—not as a rebadged off-the-shelf shallow woofer—so you get real engineering, not just marketing.

Available in both dual 2 ohm (D2) and dual 4 ohm (D4) versions, the FE Slim 8" makes wiring simple whether you’re running a single sub on a compact monoblock or multiple shallows across a seat or rear wall. Pair it with a properly sized sealed or small ported enclosure and a clean 200W RMS amp channel for best results.
