i had just recently finished building my box for two alpine 12's. they are in a slot vented box. for some reason, they do not pound as i would like them to. actually, they don't even pound as hard as my other setup (3 10's alumapro in a sealed box). is it because the subs aren't broken in yet? is it maybe my sub wiring is wrong (switching the pos and neg wires)? i'm pretty sure i wired it right for the ohms. or maybe the box is not right for them? they don't hit as low as my 3 10's. any suggestions?
Well for one check your Subsonic Filter on your amp maybe you have it too low or too high.What are you tryin to do wire your subs in parallel or series and what are the impedances of the subs,and what kinda amp are you using?Also what did you set your tuning frequency of your port to?
