Street beating an FI BTL

[btchn1 0]

Here is the system: Basic Kenwood deck (for now) feeding a US AMPS 6000. US AMPS 6000 feeding one BTL 15. For now, two runs of 0 gauge running back off a 250-300 amp alt feeding three Stinger 1700s. We want to do street beat under USACI rules which is pound the crap out of it for 30 seconds. The amp will not be ran at full tilt just so you guys know. I was wondering what kinda box you guys might recommend and should we get the fully loaded BTL or are there a few things we don't need. This will make for one of two FI systems being built this season and I will keep you all updated as the builds progress. If your interested the other is four FI BL 15s running off four MA Audio 802s in a two door s-10 blazer that will be a burp box. Thanks, Lee

How does this sound. One 15 inch BTL with the 3rd magnet, HiXm Coil, P Chamfer, and Daily options. From what I understand I don't need the cooling option for what the sub will be used for. The box will be a total of four cubic feet before subtracting sub displacement and port displacement. I see the suggestion of 12-16 square inches per cubic foot for the port. If I go with the 16 square inches per cubic foot how deep does it have to be to tune it around 38hz? Do you times 16 by 4 or by the amount left after sub and port displacement? Thanks, Lee

Could someone please at least tell me if I am right about the options to order on the BTL 15?

take the internal net volume and multiply it by 16. If you check the sticky at the top of the board it'll tell you what options are recommended. I don't think you want cooling.

you can make your port bigger if you have space.

If Im not mistaken that amp is rated at 6000W at 2 Ohms... which is a trmendous amount of power. Seeing as this is not a burp class, I would definitely get the full cooling if there is any hope of keeping the coils and sub together with 6kW on it. OI know you mentioned that it wont be run full tilt... but with 2500W + to it for daily/music I would recommend the full cooling.

3.5 to 4 cuft after port and driver will work well. Port is calculated as mentioned above by multiplying the net cuft by 12 to 16 to find a workable value in sqin.

Let me know if I can help with anything else.

Thanks,

Scott

Thanks for the help, I will make sure to get the full cooling then. I am waiting for my little brother to bring his car over so I can do some more exact measuring and see what we got to work with. I know the 6000 watts is a little overkill but I would rather have the headroom in his class then be underpowered. We have been running that amp to three older Crossfire BMF 12's and had no problems as of yet so I think the FI BTL will do all right. Anyway, thanks for the advise and I hope we will be ordering a sub soon enough. I will keep everyone up to date with the build also. Lee
