    Icon9 my alero build problem

    hello all i am going to build a custom box for my alero. it will be 2 boxes formed to the bottom of the trunk in glass and wood for the top. they will be about 4 cubic feet with 2 4" ports each. my problem is i dont know where to place my subs and ports so it will be loudest for competition. i know it was pretty loud with the subs facing the back and the ports on the opposite side of the box facing into the car. but i read that the ports need to be facing the same way as the subs. i am just plain confused. please help

    Subs firing forward, port firing to the passenger side got me doing 139.9 in bass race with a pair of 12s and 300 watts total in my g/fs alero

    so the port was on the side of the box on the side to the right of the subs?

    Re: my alero build problem

    You have the wrong vehicle for competition (trunk car; very difficult to SPL)
    Do the rear seats fold down in an Alero?

    Re: my alero build problem

    For a competition set-up I would face all forward with the largest port area you can cut
    The box will probably take most of the trunk
    For Cruz around bass face all back

    Re: my alero build problem

    I read somewhere never to put ports behind the drivers. Always ontop, below, on the side, or in front, but never in the rear.
