Awesome thanks for your time guys. I appreciate it. I'm gunna play around with those websites you listed. Bromo, what would the correct port size be? I have plenty of room for my box. It will be in the back of a Tacoma ext cab. The area is around 16 x 18 x 48, but I don't need a box that big obviously. If anybody has box/port specs around the 2.5 cu ft mark and 32 hz please share. I want to build a box asap.
