Ok so got a new car that I am trying to put subwoofers in. I put them in and it worked well for about an hour then they cut out so I went to my trunk and started looking at everything. I tightened my ground and it worked again until later that day it did the same thing. My amp now won't turn on unless I touch a little wire from the positive on the amp to the remote on the amp then it turns on but no sound comes out. Could the stock amplifier in my car have something to do with the problems I'm having? If so what does it take to fix the problem and get bumping Again?
