Make sure its ported and tune it around 38hz if u want high numbers

loudness does not always equal more db's

Cone area is another factor

I bet if you scrapped that box you have now and built a nice new ported box you would notice a big difference.

Believe it or not Boxes make a HUGE difference

yea but even my windshield moves alot more then it did before, it has to be more dbs than before...

everyone tells me to get a new box, well the biggest space i have is 35Wx14Hx22D can someone tell me the port length and size that would be good for 2 12 L7's and tell me what tuning would be BEST for daily driving

for 2

L7 12's build a ported box 5 cubes tuned to 35hz and u should have no problem hitting more than 140

I just did a quick estimate. But using those dimensions I did a quick design of 4cubes tuned at 32hz with 57sq in of port. That should be nice for the 12's. I just did a simple slot vent port 4.5 in wide

Edit: if you do a port 5in wide and a 2nd Port length of 5in, you can get 4cubes at 34.5hz with 62 sq in of port.

Well in a trunk hurts alot, but I see alot of people hatin on the subs and telling you to get whatever kind of sub they have a boner for. I have seen a single l7 hit a 145 on a TL, it has been posted here and you might get another member that has seen it also. I do agree on the try a diff box thing, but as said the people talking all the shit about you dont have shit, also does not have a clue on what kind of box you are even talking about..

So what? Listen to them and get you a **** btl with a new box and you will be hitting 150s?

can you tell me the dimensions of the box, and the port length width and height? also wouldnt 32 be a little low to have it tuned to?

Check the edit. I think that would work better. I used your exact measurements: 35x14x22.

with his measurements he can do 4cubes tuned to 37hz with a 62square inch port

your also in a suv, i guarentee if i was in a suv i would be hitting much higher numbers...

"if you do a port 5in wide and a 2nd Port length of 5in, you can get 4cubes at 34.5hz with 62 sq in of port."

does that mean have the port width be 5 inches across, and have the port length be only 5 inches? im kinda lost...i know each side of teh box would have to be 22Dx14H and the port width would be 5 inches wide but how long would the port length thats running parallel with the sides be?
