Well I am sure up on the dash it will be a couple db's less. That is obvious. I havent finished sealing off the box entirely either. Im not one that has thousands of dollars to throw into a system at every corner. I have to work my *** off for everything

thats actually what i was going to ask....it didnt looked sealed off. could be a very big gain. as for working your *** off for your equipment, thats good makes you appreciate what you have that much more. im broke because of mine

[Pioneer~Saturn]

...tuned to 43hz?

[SPL Blazer]

That number looks good for that set up. A much bigger port would get you a lot louder. There's a guy around here that competes in my shows with an Olds Cutless, four 15" T3 TSNS's and four of the MA Audio HK4000D's thats been doing 159-160. He was doing 57's last year when he had less power, pretty much like what you have.

Whys that. Its a good number on music not test tones. Im sure if he wanted to do a fart box it be alot louder.

Actually thats a really good number, considering he's got a pair of 18's in the trunk. A box that big would leave almost no room for the sound waves to move around and enter the cabin, or reach the sensor very well.

I know thats what Im saying. It is a good number. Its a built wall for music not burps.

[SPL Blazer]

Maybe I should have read his sig better, I thought he had this in a trunk not a wall. For that limited power I guess it's not bad. But for a pair of 18's in a wall on 16V I'd think it would be a little louder than that. I'm assuming this was with the seats in too, that will hurt the score a bit.

[Enellz]

Read the sig. But I've never been metered, yet...
