Description
Jeeps are famous for their versatility, durability, and off-road capability. Unfortunately, they are not known for their sound systems. This becomes increasingly apparent when the top is down, especially with large aftermarket tires. Find out what you have been missing with the Alpine PSS-23WRA Full Sound System Upgrade. This 300 watt plug and play kit is specifically designed for the Wrangler JL and Gladiator JT. It includes a high performance 8" subwoofer with built in amplifier, a pair of 1" tweeters, and a four-channel amplifier to completely overhaul your factory sound system. The PSS-23WRA is compatible with both factory and aftermarket head units, and comes with all necessary brackets, hardware, and wiring harnesses. Since the factory speakers lack high and low-end frequency range, Alpine focused their efforts on a subwoofer and tweeters.
Installation Note: On 2-door Wranglers, the PSS-23WRA will fit 2019 and newer Jeeps ONLY . It is not compatible with two-door Wranglers that have scissor style seat brackets, so it will not fit the 2018 2-door Wrangler JL. The PSS-23WRA is NOT compatible with the OEM Factory Alpine premium sound system.

Upgrade from Factory: By adding additional low end and top end, the Alpine PSS-23WRA Full Sound System Upgrade completely transforms your Jeep's factory sound system. Alpine uses amplifiers for both the subwoofer and factory speakers to completely revolutionize audio.

Alpine PSS-23WRA Full Sound System Upgrade Reviews
Definitely a huge upgrade with the sound and the bass thumps! The installation was pretty straight forward with the instructions. Great buy!
I had some installation hiccups such as the front right side speaker and tweeter kept disconnecting after raising the volume, i reinstalled everything again and again hopefully to troubleshoot but the problem still was there, finally i went to a radio repair to figure it out and they told me because the cables were near the ground electric cable , they isolated the cables from the car floor and it worked fine, the improvement was very noticeable and was totally worth it.
Just installed this system and WOW what a day and night difference in my JT! Fairly easy to install. The installation video on Quadratec really helped. Much more power! Nice highs and lows now instead of ALL mid. Definitely worth it in my humble opinion.

No, it will not. Thanks for your inquiry.
It's Saying if I have the sub woofer in the back this want work is this correct, I have the subwoofer will this install ?
Quadratec
This will not work on vehicles equipped with factory subwoofers.
Does this amplify the power going to the sound bar and kick panel speakers as well as the replacement dash tweeters and subwoofer? Thanks.
Quadratec
This is a 4 channel amp, please see the wiring diagram on page 8 of the instructions.
