With those box dimensions and a 3" round port.... 9.5" will tune it @32hz

They have it tuned @ 41 with a 5" port.

is it just me or does it seem like the 1st 2 subs on that list have really low sensitivity....82 and 79?...sounds brutal....

you want to bump, then they will bump and hit real hard and a lot good.

Go with something around 4 cubic feet.....with 60-80 sq.in. of port tuned @ around 40hz. It wont be very musical...but it'll be louder. The tiny 3" ports is whats killing you....but then again they only have 6.4mm of x-max. With that siad I'm suprised you hit 140 at all.


If you give me the max dimesions youre looking to use I can design something for you. How did you have the box facing when you got metered?

I can figure out a box....but you have to make trim pieces yourself for around it to seal the trunk off from the rest of the car or else it will sound like poo. Just give me the max width and height of the opening that the box will be able to slide into.

if you had it facinf towards the cabin...you HVAE to have the baffle (face of box where the subs are mounted) sealed off from the trunk. if you dont....you can and probably will get cancelation which will hurt your score. You'd probably be better off facing it into the trunk with the way you had it.
