The first one I encountered was in a HS buddy's late 50's Cadillac hearse. He had a bunch of intercom speakers he'd salvaged from an old school the county was tearing down in the Caddy. They would rattle that old rustbucket.
We were seniors and only went to school about a half day. The rest of the time we cruised around in that thing, usually along the ridge roads w/ various loose women we knew. He was so pumped when he got that Supertuner. It lasted about a week and a half. One day we were heading out to what was known as "Party Hill" with a couple of girls, jamming to the local free form rock FM station. The road to Party Hill passed about 150 yards from the stick of local classical music station. It overrode the rock station for a couple of seconds, then it went dead with that lovely smell of ozone.
Pioneer sent him a replacement. It went in less than a month for the same reason on a different ridge. That was his last Pioneer product.
