Posted June 1, 200817 yr Ok, so I am going infinite baffle in my e28 and have a pair of Fi X 12's. Does anyone know how well they may perform in tis type of setup? Just a little info, stock the trunk is sealed from the cabin in an e28 BMW and therefore it is good for this type of setup. I will mount the subs on the rear deck. I am definitely an SQ guy so lower spl is fine with me. However, I cannot go bigger than 12" because there is only 13" of rear deck space. I would have to cut the wall all up just to get some air moving into the cabin in a regular box setup anyway. Any tips, questions, info is appreciated.
