Heres the thing Iraggi is not doing any buisness right now he is retooling his shop and has been for like ever, so my advice to you is to talk to mechman or dc power for your alts, if you going for a daily set up how much power do you want to give your subs unless u really know what ur doing i wouldnt put much more than 3k on each sub (but thats just me) i say get like 2 AQ3500's and run 1 to each sub or 2 SAZ-3500 and run 1 each to each sub if you want some power, get urself some xs power batts and call it a day, XS can tell you how many and what kind of batterys ull need when you tell them how much power u plan on running, same with the alt companys they will tell you how many and what size ull need just based of how much power ur going to run.
