Did you run your power cables on the same side as the RCA? That's a no no unless you have a very strong signal and good cables. It gets louder when the system is cold because more power is drawn from the alternator when it's cold (more efficient) and you also just started the car, so the battery is charging from the starter load. Your 80PRS actually has a pretty strong signal surprisingly. When it gets to the amp is there slack coiled up on either the b+ cable or the RCAs? Coils make it worse</p></blockquote><p></p>
