The Stealthbox® slips under the truck's rear seat and features two of our revolutionary 10TW3 thin-line subwoofers, giving you absolutely stellar sub-bass impact and quality. We even left a perfect spot in the middle of the enclosure for a clean, hidden amplifier installation!

Contains two 10TW3-D8 subwoofers in a down-firing sealed enclosure. 800 watt power handling. Wired for a 2 ohm load. Installs under rear seat. Will not affect the folding of the rear seat or rear leg room.
Frequently Asked Questions (FAQ)
- • What generation and years of GM trucks does this specific \"CC3\" Stealthbox fit?
This enclosure is engineered exclusively for 2014–2018 Generation 3 Chevrolet Silverado and GMC Sierra Crew Cab models. It will not fit older Classic models or newer 2019+ Generation 4 trucks.
- • What factory truck interior trim color matches the \"BK2\" finish code?
The \"BK2\" designation signifies that the premium fiberglass housing is finished in JL Audio's Jet Black colorway, custom-dyed to blend flawlessly with GM’s dark black factory interior packages.
- • Will this dual 10-inch enclosure fit into a Silverado Double Cab or Extended Cab?
No. The physical dimensions and precise molding are strictly mapped out to align with the larger floor pan of a Crew Cab. It will not physically clear the limited space of Double or Extended Cabs.
- • What factory components underneath the rear seat must be removed for setup?
You must unbolt and permanently remove the under-seat factory plastic storage organizers and any OEM subwoofer gear to clear the entire floor surface for the new enclosure.
- • What final wiring load impedance does this dual-subwoofer system present?
The box comes loaded with two premium 10TW3-D8 dual-voice-coil drivers pre-wired together internally in parallel. The external terminal block presents a single 2-ohm mono load to your amp.
- • What continuous amplifier power rating do I need to drive this system optimally?
The combined handling capacity of the dual thin-line drivers is 800 watts RMS. Pair the enclosure with a high-performance monoblock amplifier pushing 600W to 800W RMS at 2 ohms.
- • Does the middle recess area in the box serve a functional installation purpose?
Yes. JL Audio intentionally engineered a perfect structural indentation directly into the center of the fiberglass shell to act as a hidden, clean mounting zone for your amplifier.
- • Why does the sub-bass output clip early or sound muddy at higher volumes?
The factory GM head unit utilizes aggressive internal EQ curves that roll off low frequencies as you turn up the volume. You must add an active integration adapter or DSP to supply a flat signal to the amp.
