Seems like a pretty broad question my friend. Are you wanting step by step instructions on an install, or are you trying to find the best place to splice in for a line out convertor to push subs? :hmm:
If you're looking for a step by step w/pics and don't know where to start I suggest you find a friend with experience wiring up stereos, buy the beer he likes, and invite him over.
Sorry, I was looking for where in the vehicle would be the best place to splice in would be. I researched more and found out about the PAC systems. I will be using that for the install. I'll also try and take step-by-step instructions with photo's to make it easier for people in the future!
