me and my friend installed my system today (hifonics amp, 2 12in kickers, sony hu (i know they suck)). at first we figured it wasnt hitting because the amp wasnt tuned, but then another friend of ours tuned it, and now its hitting a little bit, just not very hard. my friend alex (who tuned the amp) thinks its the amp, but i was told that it was a pretty good amp so i dont think its that. could the wires connecting the subwoofers on the inside of the box be bad? the box was preowned so i dont know if they wires were good to begin with. and if it is the wires, would they really keep it from hitting that much? thanks in advance.
