Alright thanks so much for your help. But still a few more questions. Ok so we got the Amp, Got the Sub, the box, and Got the 4Gauge Install kit. I followed your link to the website and found the speaker wire, Does it matter what kinda I get because there is like 4 different kinds?, Was it in my budget to get 1 DC LV4 sub or 2. Also is the head Unit I picked out good? oh and I thought of 1 more What size of sub Should I get
