so i have a 1200 watt amp powering 2 13 1/2 in subs im going to add an amp for the speakers... i basically know how to do it but what are some things i should do or use in order to improve sound quality?
Well, I don't know which part of your system you are trying to improve but if it is your stock speakers you could replace them with jensen speakers. You can buy a pair at circuit city for less than $50 bucks and they sound great. I replaced all four speakers in my Dodge ram with these Jensens and I have 10 12's in the bed of my truck and it sounds amazing.
