I am looking at putting 4 subs in the back of my explorer, what are your thoughts on which sub I should get to get the max out of it as far as SQL and SPL are concerned. I basically want the best SQL sub I can buy for 150 bucks each or less. I have a layout I am going to do that requires 4 subs and my budget is pretty tight so I dont have money to drop on 3 or 4 hundred dollar subs. I know I wont be able to get w7s, re xxx's, or anything of that caliber but what would be my best option for a low cost sql sub.
