    Is 14in enough port area for a 04S12L7? 500watts, 2.0@35hz

    Is 14in enough port area for a 04S12L7? 500watts RMS Per sub, 2.0@35hz. Im making a truck enclosure and we can only get 4.0 ft net w/o ports from behind the seats. Im shooting for about 1.8@35hz each and i planned on using two 3" ports per side @ 35-37hz

    Even at that power level its more then likely going to have alot of port noise.
    I had 28 cuin area and it made noise at 800 watt level bad with the lower notes.

    Goin for 60 sq on 2 now.........

    No sorry. You will get a lot of port noise. Maybe downgrade to a single sub in the proper enclosure size.

    1 sub proper enclosure>2 subs improper enclosure.

    Linearteam.org website predricts .04 m/s port mach, with .17 being port noise.
    I have already made the box its 4.0 net. do you think it will be ok with 6 of the 15" ports? then it woul dhave 21 per sub for 40 total? I have already cut the ports to 15" lenght, 4 of them, i could cut two more and have 3 on each side, what abotu polyfill? i dont think so though. But dont the l7's like the higher tuning ..most of the kicker spec boxes and mtx boxes are tuned higher i dont know why must be ok for the drivers...?

    I would not go higher than 37hz on a 12" driver. If you can get at least 24 square inches of port area per sub you would be fine.
