Well, I messed around with the eq and the faders and got the car sounds pretty good. the sub works, and before, it always had, but it was just really quite. So I'm getting good sound now but I still have some crackling and popping sounds when I turn on the switch. Any ideas why the stereo still pops and crackles for like the first 30 seconds to a minute?
Also, one other thing: What is happening to the amp when I turn up the volume on the head unit and it cuts out on me only in the externally amplified speakers for a second then comes back in? It does it repeatedly if I keep the volume that loud.
