I have a Toyota Avalon which comes stock with a 8" free air subwoofer in the rear deck. I also have a IDQ12 D2 sub in a .85cf sub box (not being used currently). So my question is, do I buy a new 8" free floating sub and replace the stock one OR do I take the stock sub out, leaving a 8" hole in the rear deck and place the IDQ sub with box in the trunk and use the 8" hole sort of as a port hole? Will that decrease the sound quality at all or not? I think I could go either way on this but would like some feedback. Thanks!
