So I bought an amp and subs from my friend and we hooked them up ourselves. It worked just fine for two weeks, but then I went out of town. My sister cleaned out my car for me when I was gone and when I came back, I couldn't get the amp to turn on. I've checked and reconnected all of the connections even cutting the wires down and using "fresh wiring." I thought a fuse was blown, but I was able to get it to turn on once last night, but when I tried it again 5 minutes later, it wasn't working. Any suggestions?
