Help On Box For 15" RE MT

Yep, as a lot of you may know, I have a 15" MT being run off my GP3k in my trunk. Right now my box is about 4 cubes tuned at 35, and I think it could get much louder.

So, my question is, what do you guys think I should try my next box at? I've heard from another guy with a Mazda 6 that a crx box (sub up, external aero ports firing back towards the trunk) gets the loudest in this car, and am considering doing that.

But, as for your input, what air space and tuning do you guys think I should go for? This is a daily driver, so I'm thinking of tuning between 30-34, but I'm not sure if 4 cubes is ideal for this sub for daily or what.

Thanks in advance all //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

try 4.5 cubes@ 38hz
Will consider this but I'm not really going for numbers as the d3100 gets me bumped from street classes, just going for more of a daily musical box that can get low and loud.

Oh hm I didn't people tuned that high up for music and liked it. I'll give it a try depending on what else gets suggested in here //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif.

Thanks for the replies bones, and how much port area should I be going for with the MT? I think I'm around 60 sq inches now.

60 or so would be good

no more than maybe 75sq"

 
3.5cu.ft. tuned to 40 Hz. It won't slam the low-lows, but it'll still be good and get much louder. If that's too high a tuning try 37Hz instead. As for box config, is that a hatch car? do ports up sub toward cabin

 
It's a 4 door car with a trunk, from what other's with this type of Mazda 6 have said sub up external aero's back were the loudest, but I'm not too sure about that.

I can build anything .

I'm interested in trying that 3.5 @ 37 though.
