just recently installed a new car stereo in my car, 4 channel amp and speakers, 2 channel amp and a sub, new deck, 2 farad cap, new deck, and 4 gauge wiring kit.
everything was working great until 2 days ago the 4 channel amp stop playing but the 2 channel still worked and drove home from work with just bass.
next day go to start my car and turned the key and all the dash lights turned off and so did all the power to my car. never had a problem like this before, key even got stuck in the ignition. i disconnected the fuse so my amps wouldn't be draining the battery and hooked up the battery charger all day, and it still wouldn't start the same thing happened. tested the battery at napa today and its 100% charge and health.
anyone know why this is happening?? i hooked up my 4 gauge power wire to the 12volt output on the fusebox inside the engine compartment (which seems like a stupid f*****g idea now) did i do some major electrical damage here?? need help please
