subs up and ports firing foward on the bottom...

Right now I have my subs forward with the ports at the bottom firing forward. I did a 146.0 like that. But I have noticed that the scores are a lil higher than that if the subs and ports are up

I've personally had the best luck with firing sub AND port towards the passenger side, maybe 8" - 10" from the passenger side.I've also had good luck with port and sub forward, sub forward and port side.Sub and port up haven't been that great for me (well, for roof flex I noticed a little more, but who cares about that).

Subs up, port up.

Or sub up, with aero ports firing towards driver side. (Pure SPL boxes)

I ran 2 ID Max's in a box supplied(design made by ID but I but the box) by ID and I did a 144.6 with it, but the box was alittle bit off, and one amp wasnt working right, it didnt have full output, so I could of done a bit more, the box had the woofers facing the seats, and the port running along the bottom of the box, about an inch or so tall but 16 inches wide I believe it was, sounded good too, now im debating between some more id max's or fi's or DD's . . . . .

For street SPL, the best I found testing on the TL.

Sub firing rearwards with ~2" between it and the back wall. Space the box about 6" from the passenger wall. Have external aeroports firing toward driver side wall. Also, make the box undersized from a normal ported box... and pour on the power.

Great for street SPL in an extended cab. Pressure box.
