    What box for hdc318?

    What kind of space and tuning do these subs like? Also t he general rule of thumb is 12-15in^2 of port per ft^3 correct? I also have about 8ft of 6in PVC, could I use that?

    i've had good result with them in 5 - 6 ft3... tuning depends on your application... for a burp box, i would tune high 40's low 50's, for a daily, around 35 is a good tune

    A friend of mine had one in 6.5 cubes tuned to 35hz for daily and it pounded. I was very impressed by it.

    I've seen anywhere from 5.5-7 cubes. I'd do ~6 at 34 hz.

    Re: What box for hdc318?

    ok with aero ports. i have a 8in. do you think a 6cube box with the 8in would work. im not sure what i would need to tune to is the problem. i do a daily driver type comp. no burps. its constant average play. if that info helps. just tryna get a tunning idea

    You and OP. Unless you are pressed for space, I would do slot.

    Use the power of the aero brother and get loud its easy to cut volume hard to add start at 7least test then start adding wood inside to cut the volume down til you get optimal score.

    where does your vehicle peak? I would base tuning off of that...

    Re: What box for hdc318?

    i have a blazer so i think im pretty good. im only doing a 46.5 with the slot/lport tho.i figured id be doing alil better then that. but idk. i was thinking my port was a bit big. it was a 8in x 17in lport but i cut it down to 6in. i havnt ran it as 6in yet tho. but idk if it would help much by doin that. but i guess it was worth a try
