Frequently Asked Questions (FAQ)

This dual 12" enclosure is custom-contoured for 2014–2018 Silverado/Sierra Double Cabs. Its down-firing design utilizes 1.4 cu. ft. of optimized airspace under the seat, providing maximum output without sacrificing passenger legroom.
Ensure it is seated flush against the seat riser. To prevent sliding, apply NVX SDRLR20 sound deadening to the floor. This adds a layer of grip and eliminates panel resonance, ensuring the enclosure stays locked in place during driving.
Air is likely escaping from the terminal cup or the sub-mounting flange. Use NVX SBP12 gasket foam tape to ensure a 100% airtight seal. This is critical for maintaining the high pressure needed for deep bass in a sealed enclosure.
Check the internal binding post connections. If you have a factory MyLink or IntelliLink system, use the NVX XPLOC2 Line Output Converter to ensure a clean, strong audio signal is being sent from your factory wires to your amplifier.
In the Silverado, ensure the rear seat is fully clicked down. This enclosure has a 5.75" mounting depth; if the seat won't lock, your 12" subs are too tall. Use shallow-mount drivers like the NVX SMW12D4 to ensure the seat frame clears.
Check for phase cancellation; reverse the (+) and (-) wires on one sub. To improve the low-end "warmth" in this 1.4 cu. ft. box, add Polyfil inside the chambers to simulate a larger volume and smooth out the frequency response.
Yes! The LVE-GM-SLVDCG3-D12S is the pre-loaded version. It comes with two 12" NVX subwoofers already installed and wired to 1-ohm, providing a perfectly tuned 800W RMS "drop-in" bass solution specifically for your GM truck.
