Hello..

I am trying to change my stock CD player to an Mp3 player (Pioneer) on my WRX

I have few questions before I do that:
1. Where can I find a good deal on an install kit that would flush in the Piooneer Mp3 player. (Name brand probably)

2. I have an OEM subwoofer installed. Would this subwoofer work w/ my new Piooneer Mp3? IF not, is there a thread where I could follow to make it work?

3. Does Subaru has some type of stock amplifier like a Mitsu 95 Eclipse GST (Infinity amp) to power the 4 speakers?

Thanks again....
