I pretty much know how to do everything i just want to know a few things is there a different way to power the front speakers besides running new wire to them. What i mean is can i somehow use the factory wiring to power these ("splicing" the head unit harness ?) If so how would I do that and what is the best technique for "splicing" . Also where is the best location through the fire wall to run the power cable for the amp.

I have a 2000 honda accord lx 4 cyl

Im running a JVC KD-Hdr30 head unit, I have 2-6.5 polk db 651's, 2-6x9 polk db 691's. The amp is a Crunch P1400.4 4-Channel Amp. 4 gauge power cable.

Any response would help
I know other people probably have already asked similar questions so if you could direct to those theads.

Thanks
