I have an 82 trans am. I had a pair of dd 1508s in a smalll ported box that fit in the rear "well" area and fired up towards the hatch, and the port towards drivers side. Thats the way it was loudest, and if it wasnt down in that well area, it wasnt very loud at all. Anyways i got a pair of 9515s now, i dont think im gona install them to stay in the car, just maybe to see how ridiculously loud it will get in the hatch. So im just wondering, which way would i want to face them? And which way for the port? Itd have to be on the rear seat i think, cuz it wont fit anywhere in the rear unless i make a special box which i dont think is worht it, to get any air space itd have to go on the rear seat anyways.
