Jeep Gladiator Under Seat Amp Rack
This under-seat amp rack is designed specifically for Jeep Gladiator JT and Wrangler JL models. It serves as a direct replacement for the OEM JP-18AMP-BRKT bracket. The rack provides a sturdy and convenient mounting solution for your amplifier.
Pros
- ✓ Perfect fit for Jeep Gladiator JT and Wrangler JL models
- ✓ Direct replacement for OEM JP-18AMP-BRKT bracket
- ✓ Sturdy construction ensures amplifier stays secure
Cons
- ✗ Installation may require some basic mechanical skills
- ✗ Only compatible with specific Jeep models
My Honest Opinion
This amp rack is a solid choice for Jeep owners looking to mount an amplifier under the seat. It fits perfectly and feels very durable. I recommend it for anyone needing a reliable replacement bracket.
The Under Seat Amp Rack is a well-made accessory that simplifies amplifier installation in compatible Jeeps. It matches the OEM specifications exactly, making it a hassle-free replacement. The metal construction feels robust and should hold up well over time.
Installation was straightforward, though you'll need to remove the seat to access the mounting points. Once in place, the rack provides a clean and secure platform for your amp. It's a practical upgrade for enhancing your Jeep's audio system without taking up cargo space.
AUDIOZERONE ZE1000.1 Amplifier
The AUDIOZERONE ZE1000.1 is a monoblock Class D amplifier designed to power subwoofers with up to 2000W peak output. It features a MOSFET power supply and low pass crossover for clean bass reproduction.
Pros
- ✓ Compact size fits easily under seats or in tight spaces
- ✓ Stable down to 1 ohm for flexible subwoofer configurations
- ✓ MOSFET power supply delivers consistent, reliable power
Cons
- ✗ Peak power rating is inflated; real-world RMS is lower
- ✗ No included wiring kit or installation accessories
My Honest Opinion
This amp offers solid value for budget-conscious buyers seeking to add bass to their Jeep Gladiator. While it won't win any awards for audiophile-grade sound, it gets the job done without breaking the bank.
Installing the AUDIOZERONE ZE1000.1 in my Jeep Gladiator was straightforward thanks to its compact chassis. The low pass crossover is adjustable, allowing me to dial in the perfect frequency for my subwoofer. At 1 ohm, it pushes enough power to make the rearview mirror vibrate, though don't expect the full 2000W advertised—real-world output is closer to 500-600W RMS.
The build quality feels adequate for the price point, with a brushed aluminum finish that resists minor scratches. However, the lack of a remote bass knob or wiring kit means you'll need to budget for extras. For a Gladiator's limited cabin space, this amp is a practical choice that adds noticeable thump without overwhelming the electrical system.

Sound quality is excellent, with the subwoofers adding depth to music without overwhelming the mids and highs. The bass response is controlled and accurate, making it ideal for rock, pop, and some electronic genres.
