Alpine Electronics of America, Inc. is now shipping the PSS-23WRA, a new aftermarket powered sound system upgrade for the all-new 2018 4-door Jeep Wrangler.

“Jeep Wrangler owners like to accessorize their vehicles, so the PSS-23WRA is the first aftermarket sound system upgrade for those who own the all-new 2018 Jeep Wrangler,” said Mike Anderson, vice president and general manager, brand business unit, Alpine Electronics of America, Inc. “The PSS-23WRA boosts the overall performance of the factory sound system for an increase in bass with refined music characteristics, even with the vehicle’s top off.”

Alpine’s PSS-23WRA includes a subwoofer and amplifier pre-assembled on a bracket for easy installation.

The PSS-23WRA is a powered sound system upgrade for 2018 and future model years 4-door Jeep Wrangler models that do not have the optional factory Alpine premium sound system. The 300-watt system consists of the PWE-S8 powered subwoofer, KTP-445U 4-channel ultra-compact power pack amplifier, SPR-10TW 2″ component tweeters and a remote bass knob.

When driving with the Wrangler’s top off, it can be difficult to achieve good bass reproduction due to the noise in the exposed cabin. The PSS-23WRA addresses this by positioning the subwoofer and amplifier under the front passenger’s seat using the included Wrangler-specific bracket. This configuration loads and disperses the lower frequency sound into the passenger’s foot well, producing maximized bass extension throughout the vehicle even when the top is off. Utilizing this location does not take away from usable storage space in the vehicle.

The PWE-S8 and KTP-445U are compact designs, which makes it possible for them to be installed under the passenger’s seat. Unlike traditional subwoofers, the PWE-S8 is a shallow format that measures just 13.5″ L x 9″ W x 3″ D. The PWE-S8 and KTP-445U are pre-assembled for bolt-on installation with simple wire routing. Installation accessories such as tweeter adapters, a wiring harness, and a T-harness for connection to the vehicle are included. The tweeters add high frequency response for clarity and definition and fit in the factory locations on top of the dash, so no custom installation is needed.

The PSS-23WRA is compatible with the factory Jeep base radio and an Alpine or other aftermarket head unit.
