I am looking to build an SPL box for two 15" Fi SSDs with copper coils... I am just going to switch out of my daily box to this box when I go to competitions... What size box, and tuning would be best? I have a '95 4-door Blazer it will be going in..

I was thinking something along the lines of 6ft^3 tuned to 45hz..

I think you'd be better off with flatwind & Bp power for this app unless you already have the subs

im pretty sure he's got the subs already..

he has a thread about his score in the General section

How much power and approx where do you peak at?

Larger will give you more efficiency, but you will have to balance box volume with your power as well... too large and too much power can create other issues.

1600 watts and I peak around 49hz
