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.
Jeep Specific Design: Alpine designed this kit to be completely plug-n-play for the four-door Jeep Wrangler JL and Gladiator JT. No drilling, cutting, or splicing is required. The included subwoofer/amplifier bracket bolts up directly to the passenger seat bolts. This kit is compatible with both factory and aftermarket head units.
