Buyer’s Guide: 3 Key Factors to Consider
Fitment & Space
The Gladiator’s cabin is tight, so you need to choose between under-seat enclosures (saving floor space) or larger boxes that go behind the seat or in the bed.
Sound Output & Bass Depth
Dual 12” subs deliver the deepest, loudest bass, while 8” or 10” options are more balanced for daily listening without overwhelming the cab.
Installation Complexity
Plug-and-play kits (like STINGER and MB Quart) are easier for DIYers, while custom enclosures (like Skar Audio) may require more wiring and modifications.
Frequently Asked Questions
Will these subwoofers fit under the rear seat of my Jeep Gladiator?
models, like the STINGER Dual 8” and MB Quart Dual 8”, are designed specifically for underseat fitment. Larger 10” or 12” boxes usually require removing the seat or placing them in the truck bed.

Most enclosures are passive (no amp), so you’ll need an external amp. However, the MB Quart JT-SUBA-1 comes with a built-in 400-watt amplifier for a complete plug-and-play setup.
Can I install these myself, or should I hire a professional?
