Frequently Asked Questions (FAQ)

Universal boxes aren't air-space matched and often leave "dead zones" or require seat spacers. This is CAD-designed to the Sierra’s floor hump, giving you maximum air volume for the subwoofers while keeping your seats at factory height.
Don't hook the LED controller directly to the battery. Tap into a "switched" fuse (like the cigarette lighter or accessory circuit) in the cabin fuse block. This ensures the lights only turn on when your ignition is actually on.
Since this is a sealed enclosure, set your Low Pass Filter (LPF) to around 80Hz. These subwoofers are efficient, so start with your Gain at zero and increase slowly to find the "sweet spot" before any distortion or clipping occurs.
Yes. To get the "stealth" flush fit, you must unbolt and remove the factory plastic under-seat bin. The BOOST Box uses that exact footprint to maximize internal air space for the 12" subs without hitting the seat bottom.
Check your floor mats first. This box is measured to the millimeter; a thick all-weather mat under the enclosure can lift it enough to block the seat latch. Trim or remove the section of the mat directly under the box for a perfect fit.
These come pre-wired to a 1-ohm final load. Ensure your amplifier is "1-ohm stable." If your amp is only stable at 2 or 4 ohms, you’ll need to open the box and rewire the subwoofers in series to avoid damaging your equipment.
