So I went to a sound comp and got 140.9db which is ok... I came in 2nd place. Now a friend of mine has 2x JL 12"w3 v2 sub's and got 145.3 db... I have 2x 12"W6 v2 subs and im only getting 140.9... So i was wondering if anyone could let me know on what to do to get higher. I think that i need to make a better box because that would be a big factor. If anyone has advice on the volume and port size, It would help a lot.

is your current box sealed or ported?

A professionally designed box that is properly built will raise it up, not to mention adding more power.

The box is ported. The subs are 400rms each and im running them off of 1000rms.

Just made a new box. It's 46" wide 26" tall and 15" deep. It sits in my back seat because the thing is massive. The port is 12.75" x 13.5" x 18.5" long
