[QUOTE="VereChronicus, post: 1453870, member: 565864"] Quick way to test if you have a problem in your signal cables: take the head unit out of the dash and disconnect RCAs from amp and head unit. Use a spare set of RCAs just run over the seats and to your amp and head unit. Obviously, if the noise goes away, it's in your signal cables. If not, time to start hunting deeper. First off, always ground your caps to chassis, all diagrams for those show chassis-direct short ground cables. Test your voltage at the amplifier under your normal listening (and symptom producing) volume levels. If it's dipping below 12V with caps and a 2nd battery, your alternator is taking a fat sh*t on you. Be happy to know, though, that it's waiting until you are the furthest from civilization to completely crap out. Alternators, after diodes and such pinch a loaf, tend to generate noise. Check those things foyst and get back to us wiff your findings. [/QUOTE]
