i need help to design a dual 12" box for spl

You will never be competitive in SPL competitions if you don't own or have access to a meter and if you don't put the time/money/effort into building and testing multiple boxes. If you're lucky you'll find someone who has used the exact same vehicle and done all the testing that can help you with some ideas, but it's largely trial and error.

irnlve I will try to help but what kind of SPL setup are you looking for with 2 600W daily 12 subs in that big vehicle, it may get a little loud with some work but a guy with 2 15s on the same power will likely smoke you in the meter if he's decently setup.

I can't send you a message and i'm not sure if i can tag you or something in my post.

You helped me out before with a box design for my 2 rockford p3's and i was wondering if you could put something together for my friends 2 FLI Frequency 15's in a 99 toyota corolla on a kicker 1000.1 monoblock.

Here's my old thread -

My new one -

Just comment on the new thread if you can help me out, i made some designs of my own for them but i'm not sure if they will sound good.

Thanks a lot.

just trying to do the best i can with what i have.. these subs are a beginning, hopefully soon there will be 4 and i can replicate the box that gets designed for these 2..

years past i ran Memphis car audio, pair of hp12d4 subs and a st1000d amp and was taking 1st place n my class.. no i kno these subs i have are better, and im running near twice the power..
