So I'm slowly building my system, Jackhammer 10" with matching box and still undecided on amp. However, I'm using the stock head unit, for two reasons: I like the steering wheel controls, and because where I travel if they see a aftermarket HU, they steal it. I know it can be done, I'm just curious what all I need to do it, and what I do with the RCAs and yadda yadda. And also taking suggestions for an amp.
