don't feel so bad my daily driver is only doing a 138 right now with 2 12's and alittle amp. I do have thicker wire though, I'd have to see how much I can bring to the show, I'm gonna mess with the car see if I can get it any louder, it's amazing how much having more power helps, what amp's are you using? Look like Collosus? If you need any help or need anything let me know, I plan on bringing my meter, laptop, and that to the show, besides that I think I'll just go do a number and check out everything haha, don't expect anything exciting from me.

Yea Jason there the colossus XXV. Not the best for what I'm doing but there all I have. I'm not digging the fact that the amps protect .1 ohm below there rated power.

Was able to get a little tuneing done tonight....not at a high level though due to neighbors and 8pm.
I added 4 inchs depth to the port for a VERY sligh gain but better control on the cones. I also played with my phase ajustment a little on the port side sub. Found a little more there as well.
My last 2 test wern't though out well and both had some issues but it still gives me a idea of whats going on.
2 amps(no maxxlink for now) van idealing. Clipping the liveing crap out of the amps(opps, but same a last time I cranked it) I pulled a........ 151.28..... so it's a little better than before, now to see if going to 1 amp is a gain as before.
1 amp van@2000 RPM.....clipped the crap out of the amp...and may have held the note a little longer than with 2......151.3....and the meter had fallen off the glass so there's no telling where it would have ended up for sure.

Damn Pete! It looks like you're gonna have to change that number in your sig. This is a posibility if you wanted to move the shelf you could mount the amps on top of the box and still build a bracing structure to hold the batts in place. I don't see why it would hurt to have the shelf there anyway, but that's just an idea if you decide to take it out. Hey, I got myself a battery today! Got a Powermaster XS D3100. No more shoping at Sears for batteries. The build is coming along nicely. I could definately see you getting in the high 50's to low 60's with double the power and some proper tuning time. Hell, if you got into the 60's with what you have there you might even be able to just wall the whole thing off and be a contender in ss1-2. I don't know how that would effect everything having the subs so low with a full wall, but it's always an idea. Good luck this weekend at the show and you better put up that big number you know you've got hiding in there

I can't mount the amps on the box as it would be above the window line. After this show I MIGHT try some thing that will get rid of the shelf. I think I will try some things in the box first.

Nice number, how many clicks down is that from full volume? and usually some clipping is louder than no clipping at all, but a lot of clipping can hurt you.

My number is full tilt...there is nothing left at this point as far as power goes to get louder. So it's not like I'm just not turning it up all the way......hope I can find a few more DB's.

Ummmm they said there isn't any break in time. But to be safe I did get about 2-3 hours of low power use on them first. They are still VERY stiff, you can barly move the cone by hand.

But the safety issue as he said definately outweighs the SPL loss.
No wall is a crazy class, its not so much the enclosure but the way everything behind the enclosure acts.
Just like a street car, tons of little things add up to big gains
I don't know if you read any of the posts earlier in this topic, but Pete says that the van worked better last year with less space i.e. the shelf in. No one really knows weather the shelf will hurt, help, or do nothing at all. I just hate it when people say something is for sure when they have no concrete proof of it. Until he actually test this your opinion is just that an opinion. Honestly I hope it's that easy for him to just have to take out a shelf and gain db's, but that's not always the case.

Then something else wasn't just right in that astro.
I might not know this particular astro inside and out...but I know street cars and I know some no wall tricks.
Just trying to help him out, if he doesn't want help or someone wants to cut my legs out from under me for trying to give him an easy gain then I'll just refrain from posting any tips or tricks

Wow, you took that kinda personally huh? Wasn't my intention at all to upset you. Just making a statement about how all sorts of people always make comments on other people's builds when they don't have proof of what they are suggesting. Just wondered how you were so for sure about it, that's all.

because its a no wall astro.
And its backwards from what everyone thinks would work the best is the only reason I remember it.
When people built panels and made the box flat all the way to the back of the van and stayed under the window line they lost BIG TIME.
Also I remember when some of the loudest no wall vehicles in the world built amp racks and made it pretty...and I remember a loss of SPL
Works the same way as a street vehicle with subs firing foward, anything just scattered around in the back is a loss of SPL
I've been around a while bro, been in and helped on the loudest vehicles in the world. I know what works most of the time hehe
Also thats all he would need is for it to change his frequency because of a piece of wood back there.
Go look up some pics from finals the past couple of years and look at the loudest no wall setups...see how many amp shelfs you see

You act like you were the first person to suggest removing the shelf to begin with. There were a couple of other people that made that suggestion before you even mentioned it. You're too easy to get going, so I'll stop before you get pissed off. No hard feelings here, I just get a kick out of know it alls.
