I have a jl 8w7 and im going to use a jl 500.1 mono amp with it. I have an old sony xplod 1000 watt max amp lying around but dont want to buy a new one. I have 2 polk audio door speakers and 2 jl rear deck ones they are 6 and 1/2. Will that amp work with the speakers or will it be to powerful or...
