What Db do you think?
I'm going to get a box from subthump.com pretty soon and I was wondering what db you think I could get out of this set up:
2 Fosgate 12" HE2
1Farad Cap
1.5 Cu FT per sub
750 RMS Fosgate Amp
Sealed well box (to go in the trunk space)
He said I could probably see 145 db

I would quess low 140's also. Fosgate isn't what it used to be. Just hope the amp is 750 rms not peak power. I did 145.3 legal with 1 IDmax 12 and Xtant 1001dx. Anything in the 140's is plenty loud for a daily driver. Get a custom ported box you should get pretty close to 145.

Well I appreciate the input. The amp is rated 700 RMS, but the birth certificate that came with it said it will do 749RMS. I think I am going to go with a sealed box for tighter bass. Thanks again for your opinion!

Not sure if the Rocfords just lack SPL or what, but a customer of mine in TX hit 147db legal with my standard sealed box, two alpine Type R 12s and a 700 watt kenwood amp.
That's right.
