When you're driving with the top or doors off your 2018 – Up Jeep ® Wrangler and 2020 – Up Jeep ® Gladiator, outside noise like wind, traffic, and vehicle noise can overpower your music. Alpine saw an opportunity to provide an upgrade kit for the rear soundbar that will capture the high-and-mid-levels of your music for 90-watts RMS/ 270-watts Peak Power. The SPV-65-JLT Rear Soundbar Upgrade Kit includes a 6.5-inch mid-bass driver and 1-inch teteron dome tweeter that replaces the factory 3-inch and 4-inch drivers in the 2018 – Up Jeep ® Wrangler and 2020 – Up Jeep ® Gladiator (without the Alpine OEM Premium Amplified System). The speakers and tweeters reach high-end frequencies (50kHz – 22kHz) that are often lost in the top or door-off configurations. This improves the range of sound reproduction so you can hear the details of your music. Caught in the rain? The SPV-65-JLT ensures an uninterrupted performance no matter the driving condition. Rated at IP55 for weather-resistance, the kit can withstand rain and dirt weather you're driving in the city or on the backroads. The SPV-65-JLT includes rugged, premium grills that protect your speakers and match the interior of the Jeep ®. An installation kit includes a cutting template for the rear soundbar and vehicle-specific connectors for plug-and-play installation. The SPV-65-JLT utilizes the factory bold holes and includes vehicle-specific connectors for plug-and-play installation. The SPV-65-JLT is compatible with the new 2018 – Up Jeep® Wrangler and 2020 – Up Jeep® Gladiator (without the Alpine OEM Premium Amplified System) and works with the Jeep® factory head unit, an aftermarket dash system, and the Alpine X409-WRA-JL 9-inch Weather-Resistant Navigation Receiver with Off-Road Mode.
