It's either your Logic 7 Amp or your ASK Unit going bad. If you can pinpoint exactly which speakers are cutting out you can figure out which one needs replacing. The Logic 7 Amp powers both rear door speakers, the center speaker on the dashboard, and the two subwoofers under the front seats. The ASK Unit powers the 2 speakers on the rear deck and the 2 front door speakers and tweeters.
