I just got a 2003 toyota celica gts and am set on getting a 12" SSA ICON D2. I am going for SQ and dont know whether to get a ported box or sealed. Also, I have heard that facing the sub up is a good idea in a celica because of the shape of the tailgate. Anyway, i need to know info on the box and what amp to get. My budget for the amp is about 150. Thanks for your time in advance.
