I am planning on running 2 SA-8s in my mustang install (not sure if theyll be v1 or v2 yet) and I have a few enclosure questions and need a little help. Im wanting to run them in slot ported enclosures BUT they will not fire into the trunk the will fire into a space that is sealed off from the trunk but ported through the rear deck. My questions are; 1) Whats the smallest box youd reccomend for them to perform great in a daily app and still do good in a burp situation. 2) Anybody have a box design program that will map out the whole design (dimensions and all) ? They would like to use to give me a box idea.
