The package includes two sets of 6.5” weather-resistant mid-bass drivers and 1” weather-resist tweeters that replace the front and rear soundbar factory speakers, an 8” powered, compact subwoofer, and a 4-channel power pack amplifier. The weather-resistant speakers are designed for powerful, top-off performance that’s unhindered by weather, wind, or other noise while driving. Vehicle-specific speaker connectors and pods designed for the 2018 - Up Jeep® Wrangler and 2020 – Up Jeep® Gladiator are included for plug-and-play installation. Tweeter adapter plates use the original factory tweeter locations to take the guesswork out of installation.
