i have a question, i have an rockford forgate amp about 900watts 4 channel running my highs, 4 6 1/2 speakers pioneer. i recently changed my rear speakers yesterday with 6x9 pioneers. about 400max. when i put those badboys on they didn't work. only the front speakers was working. i switch the rca front wires to the rear, and switch the rear too the front. the 6x9 came on but my fronts didn't. can anyone help me with this problem??? :thinking:
