my guess for a celica....

small box.... subs up... 2 4" aero ports facing rear... and u havent mentioned your amp yet i dont think....

my the box as small as possible... a "CRX" box.

you will have to play with it from there.... i have never personally played with a celica.

something to try. Box with sub up port up with it all the way at the back of the trunk. On low power you will actually be better with a larger box. Try something around 4 cuft firing the way I described. If you send me the exact sub model numbers I might be able to plot something up.

I am currently running trunk 0-1000 and plan to move to trunk 1001+ soon. I am getting ready for our regional event where I will only be running one of my amps so I can run both trunk 0-1000 and 0-600 stock. I will say this though. I will be louder then my WR in trunk 0-1000 which is a 154.0 posted_image
