I have two Audiopipe Mini amps in my Ranger (1 for sub, 1 for highs). When I turn on the truck I get an initial pop sound from the sub, but everything acts fine and plays fine (sounds great actually). I was troubleshooting and noticed that on the amp for my highs the "Power (Green)" light immediately lights up and on the sub amp it goes into protect for a split second if that and then the power light lights up and protect goes out. It does this with or without the RCAs connected and the amp share the same ground location (Seat bolt).
What should I try? I know this might not cause any harm, but it bothers me just the same. Every other system I have ever installed has been noise free on startup.
