try sticking with 1 size box and using an adjustable port setup. i was told the easiest way to do this was to use pvc. start long and cut ur way down until u start losing dbs.

what are you running, what vehicle and what amps?

Wow, I'd like to know that info too.

edit - found some info.

BMW hatch

FI 10'S WONT SAY WHAT THEY ARE THERE SPECIAL"

2 AUDIO QUE 2200'S

2 KENETIK 2400'S

1 DC ALT 185 @ IDLE"

1 MLA MOD CHARGING @ 15.8 VLTS UHH HUH!!!

Lucky ass. I cannot wait to get my DC Power alternator back when its done powder coating.

I want to say these are BLs?

um.. if they are special... then they must be the BTLs... otherwise he's full of

And don't get all happy... u can't run that kind of equipment in AS1 anyways.

Dude, I know.

I know its the BLs because I checked the youtubes lol.

And OP - what kind of mic are you metering your setup because from what I see in the videos, it doesn't look to be a TermLab.

then that's somewhat interesting.

Having car on with a test tone can gain u 2-2.5db typically.

oh ps... next time u go to a show.. i gots some music for you, automatic increase

u need a song with a constant focus on a single tone with a rhythmic beat in between to be legal... i gots u covered.

Songs like this are more efficient on your amp's current draw for a sustained period of a couple of good full tilt seconds without it drawing extra power for useless frequencies that will only heat your subs up and drop your score.
