i would try to port 1 sub and send the 1k to the 1 it should get louder than the 2 sealed they dont like sealed they are at best ported

162 db.

Only 162, i think he is going to be depressed with those kind of numbers...

No way to tell how much dB a subwoofer will put out in a car, too many things depend on how loud it is.

But i think you will hit around 120-142dB.

try the solo classics.

they will do fine in small sealed enclosures and from what i heard they are louder than l7s sealed.

Definitely not a good idea to put two L7's into a smalled sealed box if your goal is output

162 db.

Ha 162. That must be a conservative number

[chrisommer 4]

honestly man the only way to know is by doing it. Do you already have the L7's?

i have one so far. im ordering the next one this tuesday. thats when the box is planned to be finished (suppossed to be today)

Don't. L7's are great in the application they excel at, but a small sealed enclosure for output is not something they will do well in. Keep the one and port it, it will be significantly better than a pair sealed for what you want.

I had two CVX 10's (the round versions of the L7's) in my extended cab truck. I originally had them in a small sealed box under the rear seat and each one was getting 1000 watts, which sounded good. Then I built a ported box for one of the tens under the seat, still getting 1000 watts and it was louder and sounded better that the two subs in a sealed enclosure with double the power.

no shit??

[Kryptonite 11]

Yup, then I took out the back seat and built a huge box for them. Each one in a 1.75 ft3 enclosure, double 3/4" MDF and tuned to 35 Hz.. Insane.
