Your Jeep JL can sound as good as it looks

Your Jeep Wrangler Unlimited JL is adventure central. It goes everywhere you ask of it, but I've gotta ask... does it sound as good as it could? Alpine has a solution with the Restyle PSS-23WRA2 audio upgrade package. It'll add the audio performance that's missing in your Jeep's factory system.

Your Jeep JL can sound as good as it looks

Your Jeep Wrangler Unlimited JL is adventure central. It goes everywhere you ask of it, but I've gotta ask... does it sound as good as it could? Alpine has a solution with the Restyle PSS-23WRA2 audio upgrade package. It'll add the audio performance that's missing in your Jeep's factory system.

What you'll get

When the top is down and the wind's blowing, you can lose more than just your hat. Without a sub, your music's low end can sound less defined and the high-frequency detail can get lost with the whoosh of wind noise and the rumble of the road. This system adds Alpine's PWE-S8 powered 8" sub for some serious bass reinforcement and a pair of impressive SPV-10TW-WRA 1" Teteron dome tweeters to bring out all the high-frequency details. Of course, you'll need power for all your speakers, which is where the KTP-445U Power Pack comes in, supplying 45 watts RMS to your factory speakers and new tweeters.

Best of all, installation is simplified thanks to the included Wrangler-specific brackets, adapters, and wiring harnesses.

Features

Overview: Alpine's PSS-23WRA2 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, SPV-Series tweeters for the front dash, and a PWE-S8 8" powered subwoofer. The PSS-23WRA2 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.

Wiring: The PSS-23WRA2 system can be interfaced with a factory radio (non-amplified) or an aftermarket radio, including Alpine's 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. The provided wiring includes a 10-gauge power wire, with inline fuse holder, that gets run to the battery, providing power for both the 4-channel amp and the PWE-S8 subwoofer. Inline high-pass crossovers are provided for both tweeters.

Mounting: 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. The tweeters also include brackets, allowing them to mount in the factory locations directly to the factory screw holes.

KTP-445U: The 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 end result is a 1 Watt Signal-to-Noise Ratio of 82dB or better. Uniquely, the amplifier distortion actually decreases at higher frequencies, resulting in a clean and clear signal where your ear is most sensitive to distortion (< 0.03% THD+N @ 1W; 1% THD+N @ rated power). The Alpine KTP-445U Head Unit Power Pack provides independent controls for the Front & Rear inputs.

  • Front & Rear Gains: The Power Pack provides simple variable gain controls (speaker level: 0.5-10V, low-level: 0.2-4V) for flexibility and a wide variety of system applications.
  • Front & Rear HPF: High-Pass selectable switches for the amplifier's Front & Rear inputs allow frequency filtering for a wide variety of speakers. Choose "Full-Range" or a selectable range (60Hz, 80Hz, 120Hz) to fine-tune your crossover points (-12dB/oct.).
  • Configurable Inputs: On the bottom panel of the Power Pack there are selectable input options to accommodate Speaker-Level (0.5V-10V) or RCA (0.2V-4V) inputs.
  • 4Ch/2Ch Modes: Selectable 2-Channel & 4-Channel options give you the control to determine source inputs, and can eliminate the need for Y-adapters.

PWE-S8: The Alpine PWE-S8 is a compact self-amplified subwoofer that's designed to fit in tight spaces, such as underneath the passenger's seat, which is where the included mounting hardware allows it to be hidden. The PWE-S8 includes a built-in 120 watt Class D amp along with an 8" high-excursion subwoofer. It can accept either line- or speaker-level inputs and features an Auto Turn-on circuit that will activate the amp when it senses a signal on the speaker-level inputs. An included wired remote lets you easily adjust the bass level from the front seating area. The control can be mounted under a dash panel and gives you a level range from 0 to -20 dB, relative to the gain setting on the amplifier. Controls on the subwoofer include:

  • Gain: Can vary the input level from 0.2 - 4.0 volts line-level and 0.5 - 10 volts speaker-level.
  • Low Pass Filter: Rotary control that can set the filter cutoff between 50 - 150 Hz.
  • Phase: Switches between 0° and 180°.
  • Power Mode: Switches between SP IN (speaker-level input) and REM (wired remote input).

Tweeters: The SPV-Series tweeters plug into the outputs of the included in-line tweeter crossovers and the crossover inputs plug directly into the factory wiring. No cutting into the factory wiring is required. The crossovers have two tweeter level output options, 0 dB and +3 dB.
