I tell most people i build boxes for, Well you drive in your car all most every day. How many comps you going to go to... Then they get the point why tune for just spl when you pound everyday...If they have a lil money to spend ill build them a removable port... I guess some people worry about what others think to much... As lone as you like it thats all that counts in my book...
Daily down 2 pound works for me...
