I have twin 12" Fusion Sub's in a ported enclosure in the boot of my car... I have them directed into the cabin, to the front bascially... my sisters friends reckon that they should be directed towards the rear of the vehicle away from the cabin... I'm looking for the opinion of you peeps who appear to have a general idea of what you're talking about...
on the tl my car was louder facing the rear. we even sealed it off from the trunk and i lost almost half a db. it depends on the setup, install, and the car u wont know unless u get it metered both ways. sounding louder isnt always louder
