Why Choose JL Audio SB-GM-SLVD4/10TW3 Stealthbox System?
Bringing New Levels of Interior Refinement
The fourth generation of GM’s full-size truck boasts major enhancements in technology and power, all packed in a larger body with a refined interior. Sadly, the factory audio options are still deficient in the bass delivery department.
Absolutely Stellar Sub-bass Impact and Quality
Our Stealthbox® for the Double Cab version features an all-fiberglass, sealed enclosure design that mounts under the rear seat and requires no holes to be drilled for installation. Outfitted with a pair of our revolutionary 10TW3 thin-line subwoofers, this Stealthbox® fills your truck with stunning amounts of JL Audio bass, with no intrusion on cab space. We even left a recess on the Stealthbox's top for amplifier installation, if desired.
Frequently Asked Questions (FAQ)
- • Will this \"SLVD4\" model fit into my 2019-Up Chevrolet Silverado Crew Cab truck?
No. The \"SLVD4\" designation is custom-molded exclusively for the smaller floor space of Double Cab (Extended Cab) models and will not span a Crew Cab floor.
- • What generation or model years is this particular under-seat enclosure built for?
It is mapped strictly for Generation 4 GM trucks, covering 2019-Up Chevrolet Silverado and GMC Sierra 1500, 2500, and 3500 Double Cabs (excluding Silverado "LD" models).
- • What factory hardware under the rear bench seat needs to be permanently modified?
No structural drilling is required, but you must completely unbolt and remove the factory-installed plastic under-seat storage tray or organizer bins to clear a flat area for the box.
- • What final wiring load impedance do these dual 10-inch subwoofers present to an amp?
The enclosure houses two 10TW3-D8 drivers pre-wired together internally in a parallel circuit. The external spring terminal block outputs a single, stable 2-ohm mono load.
- • What is the recommended continuous RMS amplifier power rating for this enclosure?
The combined thin-line drivers handle up to 800 watts continuous RMS. For clean performance, drive it with a premium monoblock amplifier pushing 600W to 800W RMS at 2 ohms.
- • Will installing this down-firing fiberglass box restrict my rear seats from folding down?
No. JL Audio precision-molded the slope of the fiberglass shell so your rear bench seat cushions can fold flat down, lock for riders, or flip back up seamlessly.
- • Is there an integrated layout space on the box structure to mount my system amplifier?
Yes. The top surface of the fiberglass enclosure features a custom-engineered, recessed panel zone meant specifically to house and hide a small-footprint monoblock amplifier.
- • Why does the sub-bass output clip heavily or sound weak at upper radio volumes?
The factory GM Infotainment head unit automatically applies an internal equalization curve that pulls out low frequencies at higher volumes. An active line-output converter or DSP is required to fix it.
