Re: Amp wiring and voltage drop problems HELP!
I don't understand the 12V/7V part - where are you measuring? Power to the amp should come directly from the battery and not change with ignition switch.
What is the LOC powered from?
Ideally you want to tap the LOC from the HU before the factory amp, but you need to know what the signal levels are... some systems use speaker levels some have low level signals. I dunno what a monsoon has.
