I need to figure out what I need to do. I want a sub that is going to put out alot of presure. Should I use 12's or 15's. which is better.

1,000 for all for

yes I would sell them

I have a 4 JL w612v2 that I want to sell or trade for 15's. All in perfect working condition. But I want more presure and their not cutting it.

what kind off box should they be in

It really dosent sound like a kazoo. The subs are turnd around that was the first thing I don when I got the car. It does hit but not alot of presure. I wish I could put a video of it to show you

Directed said that you can link them together and get about 5k out of them but maybe they are over rated. but they are not linked together. and they are 1200 rms. and the box is 15 h x 20 d x17 w

The box is not 1 box for all 4 subs. It is divided for all 4 subs. Each box is 15 H x 20 D x 17 W and the port is not srait it bends. Its 1 inch wide and 18 inchs long then bends and then goes for 13.5 inches then bends again and goes for 2.25 inches.

Yes I can measure it. And I know the box is built for the subs. How do I put a pic on here so I can show you.

I have enouhg power the amps about 1200 rms each. And the subs are 400 to 500 watt each. But I have no idea abot the box because it was in the car befor i got it. The guy said that it was buit by mobile one

I have a 97 gmc jimmy with a wall of 4 JL w612v2 with two directed 1500d. Its got a little presure but not a enough for 4 12. atleast i dont think so. Mybe its the subs. Can I get some help.
