When the engine is turned off and im listening to any deep music or loud-ish music my head unit keeps shutting off for seconds at a time. The rear heat sink gets incredibly hot. When the engine is running it just gets really distorted and staticy but the music will not stall out like its doing in the video. Anyone have any suggestions?


YouTube - Volvo 240 radio short?

I had "professionals" install and bypass the original amplifier and install the new wiring harness.
