what do you think my chances of hitting 140 with two 12" L7s powered by pg tantrum 1200.1 in a 5.3cu box(internally) tuned to 40hz would be.. i know im going to get loud but im trying to hit 140ish with this setup..

Sorry for the caps........been typing military **** all day lol


okay is the the back seat folded down, deck ported?? sitting on the back seat or what here?? Also are we still in the caddi and what mic?? There are tons of variables here man and I mean TONS and also are the subs in the trunk?? Box is ported so how many square feet of port???

178.44621 will be your final score. world record here. :)

i would say its possible.

biggest questions is, how much deadening did you use?

should do it... but again I've seen better setups hitting lower, and lesser setups hitting higher... have fun no matter what :)

Like I said, you'll be close no doubt, with some playing around you should be able to get it. Take the rear speakers out of the rear dash, play around moving the box as much as you can, and see where that gets you, also try moving seat configurations around and trying tons of little things like that to help. It's doable, dBDrag legal style might be tough but I'm sure you'll do it.

PS Dave, are you running Street C next season? Or Street Max?

Charge your battery overnight. That should help. I would say you got about a 500,000 out of a 1,000,000 chance.

Considering I had a Tantrum 1200.1 hooked up to 2 12" L7's, id say if you even have a decent box you should already be hitting 140. Have you ever gotten your car tested?

I'm in the same boat as all of you. Same setup even, just older version of subs. BTW: where can I get my system tested? I live in Dallas if that helps...
Thanks, Matt

i have about 4 layers of peal and seal on entire trunk, had 6 on lid but it peeled off, 6x9s are removed, seats dont fold down. i'm not asking anybody to predict my score, im asking if you think what i have is capable of it.

140 db's isnt very hard to do man should do it easy in the right box with enough watts and 6 layers on the truck lid....****!!! lol

I dont know yet, I'll probably start out Street C, but I really want to build a wall, so I'll probably end up in street max 3-4....

Eventually I want to do Super Street 5+ w/ 8 of the 12"s I have now.... to bad my @ss is broke right now :greedy:

Last year I was around PA and one show in MD, next year I'll try to hit as many as I can...

I'll be getting all my stereo stuff straightened up after the holidays... pondering about it till then anyhow.

Hit me up when some are going on, I aint to far and wouldnt mind driving down to check some out, I got nothing to comp with right now lol but 2 12's and a small amp. Sold most of my stuff. Because of when my daughter was born. But I have a suv. And I am really looking to do something sick to it this winter/ next yr. I just got layed off from work and now have time to work with some stuff and calcs etc. So let me know though I would like to meet up with you guys down there for sure.
