I have built hundreds of boxes in my days but never a tunnel. my next vehicle is going to have 12 15's in a tunnel. i need as much cone area as possible se thats how this number came to be. i should have plenty of room in my yukon for it.
should the rear chambers of the tunnel be sealed or ported. my goal is crazy lows with big numbers.
i know some people just wing it and build them and some model off a 4th or 6th order. if somone could give me good solid advice that has experience with these types i am willing to PP money for your time/ design
woofers will be Treo TE15's and the amp is a JBL a6000
woofers like 1.7FT sealed and 2.5 ported.
