hey guys just picked up a pioneer in dash double din that im gonna put in my 06 ram. My question is i have the infinity soud system so i no that i need to get that kit to allow me to use the factory amp. so where do i pick that up. also does anyone have a used one and now is it worth it to go that route or should i just run speaker wire to the door speakers and rear speakers. which one will give me better sound.
thanks guys

 

IMO you're better to run new speaker wire yourself and remove the factory amp.
It sure makes changing speakers down the road a lot less hassel
