JL Audio SB-GM-COCREW2G/10TW3 Stealthbox System Front Left Angled View
Larger Body and Upscale Interior

GM’s mid-size truck returns with major enhancements in power and technology, all packaged in a larger body and upscale interior with all the trimmings. Unfortunately, the factory audio systems are still lacking in the bass delivery department.

JL Audio's Stealthbox® features an all-fiberglass, sealed enclosure design that installs under the rear seat and requires no holes to be drilled for installation. Equipped with their revolutionary 10TW3 thin-line subwoofer, this Stealthbox® fills your truck with powerful, deep JL Audio bass, with no intrusion on cab space.

Sealed Enclosure

The Hard Data: Contains one 10TW3-D4 subwoofer in a sealed enclosure. 400 watt power handling. Wired for 2 ohm mono. Installs under the rear bench seat. Does not affect folding or reclining of seat. Requires removal of under seat storage tray.

Frequently Asked Questions (FAQ)


  • • Will this Stealthbox fit in an Extended Cab or Regular Cab Colorado or Canyon?
    No. This enclosure (SB-GM-COCREW2G/10TW3) is engineered strictly for the distinct floor contour of 2015–2022 Chevrolet Colorado and GMC Canyon Crew Cab trucks.
  • • What factory parts do I need to remove from beneath the rear bench seat?
    You must permanently unbolt and completely remove the factory-installed plastic under-seat storage tray to clear the mandatory space required for the fiberglass box.
  • • Do I need to drill any holes into my truck's floor pan to secure it?
    No. This specific Stealthbox is designed for a completely drill-free installation and mounts securely beneath the rear bench seat without modifying the metal chassis.
  • • Will installing this box prevent the rear seats from folding down or locking properly?
    No. The slim, molded profile of the fiberglass housing drops seamlessly under the rear bench without interfering with normal passenger seating, folding, or flipping mechanics.
  • • What final wiring load impedance does this single 10-inch enclosure present to my amp?
    The enclosure houses a single 10TW3-D4 dual voice coil subwoofer that is internally pre-wired in parallel to output a final 2-ohm mono load at the external terminal posts.
  • • What continuous RMS amplifier wattage is ideal for powering this thin-line sub?
    The loaded 10TW3 speaker handles up to 400 watts continuous RMS. For optimal dynamics, match it with a clean monoblock car amplifier that delivers 300W to 400W RMS at 2 ohms.
  • • Why does the low-end bass cut out significantly as I turn up the factory MyLink radio?
    The factory GM head unit utilizes aggressive internal equalization that automatically strips low frequencies at higher volumes to protect weak stock speakers. You need an active line-output converter or DSP to restore the signal.
  • • Can I upgrade the internal driver to a deeper subwoofer like a 10W3v3 later on?
    No. The internal mounting depth and exact air volume of this sealed fiberglass structure are strictly restricted to the flat dimensions of the 10TW3 thin-line driver series.
