Can someone design me a box for two 15" Q powers? Need the subs and port on the front. Port between the two subs. Rap will be the main thing played on it.

Max external dimensions:
50 wide X 20 tall X whatever deep

So 45 wide x 18 tall x whatever deep
or smaller would prolly be good just to make it a less tight fit

sounds best at 36 hz, be careful with them.

36 not a little high? not doubting you...i dont know much about q power..just asking.

also why do you say be careful?

But could someone please make me a design. I could do it I just haven't figured out how to do middle ports yet...just the ones that are on the side.

I know I am horrible at sketchup...but I did this in about 3 minutes.

I probably figured up the tuning wrong. But tell me if its right...and if it would be good for the q powers.

If my calculations are correct (which they probably aren't, because im not good at middle ports) this should be around 5 cubic feet tuned to 34 hz.

i can do you up a design real quick if you want.

what kind of tuning you looking for?

what height and width would you prefer (not just max, but a preference)?

port area?

box volume?

Man I dont even now what the q powers need/like. I'm just mostly a kicker guy. Like I said this is for a friend. He listens to mostly rap so I was thinking around 34 hz.

I would say no more than 45" wide....18" tall. Then the depth can be whatever you need because its going in the bed of the truck.

hey bro, i have an avalanche, if your driving the EXT, we have the same body style. 49"x22"xwhatever deep will fit perfectly snug, snug enough to where you have to push it back into the bed of the truck from inside the truck with the window and gate out.

honestly since i dont have much to work with at all with these subs (as you can see by the link)

just do:

45" wide
18" high
22.5" deep

make the port 5" wide, 16.5" tall (hell even 82.5 sq in of port is probably over kill for these subs), 16" deep. this will put you at ~7.5^3ft with ~35hz tuning.

I decided to just do the port on the side instead of the middle since its quite a bit easier to do.

5.5 cubic ft tuned to 34 hz with 78 square inches of port area?

That sound good? Too small? too much port area?

well the lumber store was closed today so I wasn't able to buy the wood to build the box.

So I still have a little time to get some input on the above box.
