While the exhaust on this 430 sings like an Italian opera singer, the stereo left a little to be desired. We took care of it by sliding JL Audio's thin W5 subwoofers behind the seats in a custom built and trimmed enclosure. The beautiful stitch work matches the factory trim perfectly to give the stereo a factory installed appearance. Under the trunk lid we mounted a couple of JL's HD amplifiers for a serious increase in aural horsepower. We topped it all off with an Alpine head unit.
