I have a 93 civic ex coupe manual. I recently installed 2 6X9 240 watts each and 4 6 1/2's. Their powered by 2 amps one is 400 watts with 4 channels and one 300 watts with two channels. I also have 2 10" subs in the back. After the installation when i turned the headlights on the cars light would dim and ligth back up if i hit the gas. After this happened I had to boost my car to start the next time. After this I stopped using my radio and this stopped happening for a few days. Then if i turn on my headlights it started to happen again. Is it my battery alternator or both?
