SO I just installed my brand new Kenwood X890(sexy deck) and I used a metra wiring harness. Now that I got everything connected and I put it all back together my car is vibrating pretty strong and the RPM's are really down at idle. The actually cut out the first two times I started it. What could be causing this. Would it be some kind of short?
