Re: Need help! New radio subs won't work!!
Not sure exactly what you are asking? But if all you did was hook the Kenwood to the factory harness with an adapter, there is no power going to the door subs. You cannot use the factory amps with an aftermarket radio, so you need to run cables from the Kenwood to a new amp and from the amp to the door speakers. If you changed out the pos factory 8", to a svc sub or dvc 4ohm, then you only need a two channel amp, with the factory dvc 2ohm's, you will need a 4 channel amp. You can tap into the factory speaker harnesses located at the factory amps which are above the kick panel in the driver's footwell. Did you change all of the other speakers? Otherwise the sound will not be any better than the Shaker 500, which I think sounds real good with the right upgrades.
