We are all here to help each other in any ways. About 2 weeks ago we were discussing about the IPOD with stock HU and alot of things are here in old threads.

I have installed my AMP and Sub with the stock HU and it souds nice.
I have Pioneers on the back, Audiobahn components in the front and a 1000W sub. My friend installed it for me and the way he did it is there is minimum bass from the Rear and front speakers but the Sub delivers all the bass from the back. I use the Bass control of the HeadUnit and the Amp goes off when I power off the radio or turn off the ignition.
Belive me I have NO separate bass control or power switch for the amp, Its all hooked up to the Stock CD player. I can ask him how he did it if anybody want to know.

Dont take me wrong here but Iam just trying to help you.
