I can build just about anything if given the chance.
Send me the specs from the sub and Max measurments for the setup.
What are you going to put the 3 15's in?
I have a box started for 3 for my nissan pickup.
I think it is W52"x B15" x T 13" xT21" If you can use this box I will put the front on with double 3/4"
I was going to put 3 15" ma audio 15il's in a sealed box. But I still like my 152 db out of 2 15" synergy subs in a Ported box. If you can use the box for three 15's I will sell it for $75 uncarpted. Let me know I can take all kinds of pics.
I got a buddy who lives in middle IL I was planning on taking a trip to see him Next friday. Maybe you could meet half way?
Do you have any audio to trade?
