Hi, pretty new to this but would appreciate some help. Every time I turn my head unit on or every time I change song My sub makes a single, loud bass noise which is real annoying. Help Would be much appreciated! Luke.
it could be a head unit issue or the amp. one way to single out which one is to disconnect the rcas at the amp, then turn on the radio. if the noise is gone then its the head or the rcas from the head. if its still there it could be in the amp or a loose wire. usually the ground wire. good luck.
