ok so i am gonna go with solo baric powered by my mtx 1501d. now i wanna know which one(s) and what size. i was lookin at one 15 inch l7. then i was lookin at 2 15 inch l5s. i was also lookin at two 12 inch l5s or just 1 12 inch l7. what is the better buy since i cannot afford 2 l7s, unless i get the 10 inch model...but that just seems too small to me. i was also lookin at a single 18 inch Resonant Engineering HC series. but i mean how much would a box cost for one of those things. keep in mind that this is going into the back of a 96 explorer sportif it helps any. all and any suggestions are wanted. i just want a block poundin system with the amp i already have. what are some ideal spl setups you guys would have?
