HELP me wire my new system

if i bought one of those port tubes and cut a hole in the side of the box then put the port in it would it pound a bit more, or would it just screw the sound quality.?

Seems to me a single 12" getting 400 watts RMS should hit quite hard in a truck cab. I go back the the wiring. Is it wired exactly as pictured. I mean did you jump both the positive and negative coils then run the positive from 1 coil and the negative from the other coil to the amp? If the coils aren't jumped, it is incorrectly wired. Another way is to just run 2 sets of wires off the positive and negative of each coil to the positives and negative on the amp. You could term both sets to the boxes connector plate and run 1 set to the amp. That CRV is a 1 cubic foot box should in fact sound a bit boomy (or have a accented output probably around 60/80 Hz as that box is on the lower limit size wise for that woofer. What ever you do don't try and port this 1 cub foot box //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif I think the CRV's start out at around 2.5 cubic feet for ported designs. Turn all your head units controls to flat (make sure the loudness is off to) turn both the amps gain to min and start over with the gain on the amp. After you get this set so theirs NO distortion at a "reasonable volume", feel free to tweak up the amp bass circuit gain until you like the sound (I have never gone more than 6db myself). Then turn her up and finish the main gain until you here distortion. Of course 1st make sure you got the sub wired correctly for some reason I think its not. That sub should kick pretty hard in a truck cab with that power, though your not gonna set SPL records with it.

i have 2 small pieces of wire, one runing pos to pos, one runing neg to neg./

then i have speaker wire running from the positive and negative to the pos and neg on the amp

That is correct. The other way to run it would be to run 2 sets of wires from the amp (4 total). You would have 2 POS+ wires (one for each VC) and 2 NEG- wires (one for each VC). But to be honest, you should not really be able to tell a difference.

Sounds to me like you just have more expectations from this setup than you should. A single 12in in a sealed box is not going to hit that hard. It will sound good if the source is clean, but it is not going to be the system that people are going to hear from a distance.
