Frequently Asked Questions (FAQ)


Since it's pre-wired to 1-ohm with a 1200W RMS rating, look for a Monoblock Class D amp stable at 1-ohm that delivers 1000W–1200W RMS. This ensures the SQW subwoofers have enough "headroom" to play cleanly without clipping.
Connect the RGB controller’s power leads to a 12V switched source (like a cigarette lighter or fuse tap) so the lights turn off with the truck. Use the Bluetooth app on your phone to sync colors—no extra dash switches needed.
For the best fit and to prevent the subs from hitting the floor (excursion), it's best to remove all-weather rubber mats. If using thin factory carpet mats, ensure the box sits level so the down-firing subs have room to "breathe."
Most GMC/Chevy Crew Cabs with under-seat storage require the tray to be unbolted and removed. This enclosure is designed to utilize that entire footprint to provide the 1.8 cubic feet of air space needed for deep bass.
The box is heavy, adding a layer of NVX sound damping material to the floor and the underside of the seat frame prevents "metal-on-box" rattles and tightens the overall bass response.
The "custom-fit" design is snug, but for safety, use the included mounting hardware or heavy-duty Velcro on the bottom carpet. This keeps the 40lb box stationary during quick stops while protecting your internal wiring.
