Product Description

Alpine PSS-23WRA Powered System Upgrade for 2018-Up Jeep® Wrangler Unlimited JL

Alpine PSS-23WRA is a dedicated 300 watt sound system designed specifically for 2018  Up Jeep Wrangler Unlimited JL vehicles not equipped with a factory amplified sound system. The system includes a KTP-445U 4 x 45 watt amplifier, SPR-10TW tweeters for the front dash, and a PWE-S8 8″ powered subwoofer. The PSS-23WRA also includes a remote bass knob, for changing the bass level from the dash, along with all the mounting hardware and wiring harnesses necessary for mounting and adapting into the factory system.


Alpine PSS-23WRA system can be interfaced with a factory radio (non-amplified) or an aftermarket radio, including Alpine Restyle headunits. The included T-harness interfaces the factory wiring in the dash, providing either a speaker-level signal from a factory radio or an RCA line-level signal from an aftermarket radio, to feed to the Alpine KTP-445U amplifier. The T-harness also feeds the amplified return signal back into the factory wiring and out to each of the speakers, utilizing the factory speaker wires.


Alpine provides a pre-attached bracket that mounts both the KTP-445U amp and the PWE-S8 subwoofer underneath the front passenger side seat. This means no usable space in the vehicle is taken up by the sound system. Each of the two tweeters also include pre-attached brackets, allowing them to sit in the factory locations and mount directly to the factory screw holes.


Alpine KTP-445U Head Unit Power Pack is a power upgrade amplifier that allows you to add higher output and more dynamic response to your aftermarket or factory installed car stereo system (without factory amplifiers). The Power Pack employs a 45 watt x 4 channel amplifier with an unbelievably low noise floor, taking extra care to ensure a clean signal path, with no extraneous interference.


The included SPR-10TW tweeters are perfect for adding the extra high-end signals that are often missing from factory systems. The tweeter’s pre-attached mounting brackets are designed to match perfectly to the factory mounting location and allow the tweeter to be tilted up to 15˚ in any direction to help focus the sound towards your ears. Each crossover has four tweeter level options, allowing you to precisely tune the high frequencies to the car interior and tweeter placement. Using the supplied jumpers select 0dB (no attenuation), -2dB, -4dB, or -6dB.
