2002 Ford F-150 The dash looks much more modern thanks to the new Alpine radio. To help tame the back wall resonances the crew applied a layer of damping material. Two separate enclosures were fabricated for the four subwoofers. The enclosure and amplifier mounting plate were test-fit for precision. The enclosure provides the bass the client wanted and looks great doing it. We were careful to make sure the client didn’t lose any legroom. The Arc Audio amplifier powers all the speakers in the truck. LED lighting was used to highlight the JL Audio amplifier. A pair of Audiofrog tweeters were installed in the tops of the doors. One set of Audiofrog midbasses were installed in the factory locations of the front doors. The Audiofrog tweeter looked like a factory upgrade. An additional set of Audiofrog speakers were installed in the kick panel location. The doors were sound proofed with a layer of soundskins damping material.
