Frequently Asked Questions (FAQ)


  • • Will this model fit a Chevrolet Silverado or GMC Sierra Crew Cab truck?
    No. The \"SLVD\" model is custom-engineered exclusively for the shorter floor pan layout of 2014–2018 Double Cab (Extended Cab) trucks. It will not fit Crew Cab or Regular Cab models.
  • • What interior color configuration does the \"BK\" suffix match in my GM truck?
    The \"BK\" code signifies an Ebony / Jet Black finish. It is factory-carpet-matched to blend seamlessly with 2014–2018 trucks equipped with Jet Black or Dark Ash interior options.
  • • What factory truck components must be permanently removed for installation?
    You must fully unbolt and permanently remove the factory-installed plastic under-seat storage tray (if your truck has one) to allow the fiberglass box to rest flush against the floor.
  • • What final wiring load impedance does this dual 10-inch enclosure present?
    The enclosure features two 10TW1-4 thin-line subwoofers pre-wired together internally in a parallel configuration. The single terminal block outputs a final 2-ohm mono load.
  • • What continuous amplifier power range is recommended to drive this system safely?
    The combined continuous power handling capacity of the dual thin-line drivers is 600 watts RMS. Match the box with a monoblock car amplifier that delivers between 400W and 600W RMS cleanly at 2 ohms.
  • • Will installing this enclosure prevent the rear seats from folding down or flip-up use?
    No. JL Audio precision-molded the low-profile fiberglass housing so it rests entirely out of the way, meaning rear seat folding, flipping, and legroom remain 100% unaffected.
  • • Do I need to buy protective speaker grilles separately to shield the woofers?
    No. The enclosure is designed as an up-firing system and comes equipped with durable, heavy-duty steel mesh grilles pre-installed to safeguard both 10TW1 drivers from passenger seat contact.
  • • Why does the sub-bass output seem heavily muted or lose punch at high volume?
    The factory GM MyLink head unit uses aggressive internal equalization curves that strip away low-end bass frequencies as you increase the volume. An active line-output converter or integration module is required to deliver a flat signal.
