    Sub & Port direction in a truck.

    Basically what it says. Silverado 1500 ext cab. I took out the back seat and made a platform for the enclosure to sit on. Its a 10^3ft net box, for 2 18'' mach audio mj 18m's.

    I want to go with subs up, and port up. (port all the way to the passenger side of the box) (id prefer middle but wouldn't work im sure)

    any suggestions or would this just cancel out? should i go subs forward, port up?

    Re: Sub & Port direction in a truck.

    i wouldn't point either up. i have an s10, and it didn't work as well up, as both forward. subs forward, port to a side seems good. downfiring worked well also. when i did subs up, i seemed to lose audible loudness using the same equipment.

    word, so no port up either?

    i have this lame sub that i tried up facing up and forward. i didn' tknow which would be best.

    i thought if both sub and port were in the same direction, they could cancel?

    Re: Sub & Port direction in a truck.

    i don't think i would downfire

    my dims are - height = (want 16'', but can go 20'')
    depth (front to back) = 28''-30'')
    width = 60''

    Re: Sub & Port direction in a truck.

    what would downfiring do?

    its on a platform that sits basically level with the a ss part of the front seats. no back seat, all space
