Why Choose Alpine PSS-23WRA2 Vehicle Specific Bundle?
Featuring a Powered Subwoofer
Enjoy premium sound quality even with your JL’s top off! The PSS-23WRA is a 300 watt powered system upgrade featuring a powered subwoofer, amplifier, and tweeters for the 2018-Up Jeep Wrangler Unlimited JL without the factory amplified system. The PSS-23WRA provides excellent sound performance whether the JL’s top is on or off.
Disperse Lower Frequency
The PWE-S8 subwoofer is engineered to load and disperse lower frequency sound into the passenger’s foot well area to maximize bass extension throughout the Jeep for great sound with the top on or off. Included with the subwoofer is a remote bass knob so you can control the bass level from the convenience of your dashboard. The Included 4-channel amplifier more than doubles the power over the factory system allowing you to enjoy your tunes with the top off.
Mounting Brackets Included
The PWE-S8 Powered Subwoofer and KTP-445U Power Pack Amplifier don’t take up much since they mount under the passenger’s seat. The two products come pre-connected for easy, bolt-in installation with simple wire routing. Mounting brackets for the products are included as well.
Frequently Asked Questions (FAQ)
- • Which Jeep models is this audio bundle designed for?
This package is engineered for select Jeep Wrangler models using a vehicle-specific installation. Always verify your vehicle's model year and trim before purchasing.
- • Will this upgrade drain my Jeep's battery when the vehicle is parked?
No, the amplifier is designed to power down with the vehicle when installed correctly. If you experience battery drain, inspect the power wiring and remote turn-on connection.
- • Why doesn't the subwoofer produce enough bass after installation?
Weak bass is often caused by incorrect amplifier settings or improper wiring connections. Adjusting the gain and crossover while checking the wiring usually improves performance.
- • Can I adjust the bass level without changing the stereo volume?
Yes, the included remote bass-level controller lets you increase or decrease subwoofer output independently. This makes it easy to fine-tune the bass for different music styles.
- • Will this package improve the factory sound system without replacing the radio?
Yes, it is designed to enhance the factory audio system while keeping the original head unit. The amplifier, tweeters, and powered subwoofer provide noticeable improvements in clarity and bass.
- • Why do I hear distortion at higher volumes?
Distortion is commonly caused by excessive gain settings or clipped audio signals. Proper amplifier tuning helps maintain clean sound even at louder listening levels.
- • Do the included tweeters make a noticeable difference?
Yes, the dedicated tweeters improve high-frequency detail and vocal clarity compared to most factory speakers. They also help create a wider and more balanced soundstage.
- • Will the powered subwoofer take up a lot of cargo space?
No, the subwoofer is mounted on a vehicle-specific bracket to maximize available interior space. Its compact design keeps the cargo area functional for everyday use.
- • Can I add more speakers or amplifiers in the future?
Yes, many owners expand their systems with additional speakers or amplifiers over time. Planning future upgrades carefully will help maintain balanced system performance.
- • Can I install this bundle if my Jeep already has a premium factory sound system?
