Soo i have a 450-500 Watt amp and a 10-12 inch sub i wanna put in my car. but i dont want to pay like 100$ for someone to install it. where would be the cheapest place to go? or would it be too hard to do it myself? because i wanna keep my stock deck because of the steering wheel controls on it. would 4 or 8 gauge wires be best? i would know how to run the wires and everything besides the whole thing with the stock deck. dont i need some sort of converter thing?
