Hey Guys, I just registered with the hope that someone could help me fix a problem with my car stereo. Here is how I have it set up. I have a brand new Panasonic Head Unit (3 months old) which powers the 6 speakers inside my 05 Hyundai Tiburon. I also have RCA's running from the head unit to an amp in the trunk which powers my two subs. Recently, when turning my stereo/car off, changing sources on the head unit, or turning the volume to zero, I get a loud pop out of the subs and back right speaker. If I unplug the RCA's at either location, the pop only comes out of the back right speaker. The speakers all work fine it seems when the volume is up and music is playing. Any Ideas? Thanks guys.
