OK, so i'm new at this, and i'm sure you've heard that a thousand times...but I've got a pioneer deck pushing 2 4"'s(lame, i know) and 2 6x9's. I put bassblockers on the 4's, and the 6x9's are in boxes behind my seat on the shelf. I have 2 problems---#1--When i crank up my music, the 4's start sounding digital or something, i think it's the bassblockers or something, but i'm not sure! #2--My 6x9's are only playing bass! No mids or highs. could that be a wiring problem or the bassblockers? Also, i'll gladly take advice for a better system (at least as much as can fit into a small pickup cab!) I really want something good, but not crazy expensive. Ok, thanks for all your help!
