Can someone design me a box for two alpine type r 15's 04 models.

Heres the specs for the subs.

Sensitivity 89dB
Frequency Response 22 - 1k Hz
RMS Power Range (Watts) 200-500
Peak Power Handling (Watts) 1500
Top Mount Depth (inches) 8 3/4
Bottom Mount Depth (inches) 9 11/16
Cutout Diameter or Length (inches) 13 3/4
Vas (liters) 98
Fs (Hz) 24
Qts 0.48
Xmax (millimeters) 14.5

Sub up, port back would be nice, around 6cuft or so, tuned around 30-37hz. If this is to much to ask then forget about it. And if not, thanks.

ima run the specs through the bbp6 when i get home. i just started using that and it is fun. only thing bad is that you have to convert the inches to metric. damn.

around what frequecy do you want the box to peak at? what is the resonant frequency of the car the box is going in?

could prolly do a t-line too if you wanted to tune higher than Fs and use bass boost 3db at tuning. it would be a larger box though. let me know if your interested, its slightly harder to design lol well actually its easy, just more time consuming

he didn't finish yet. so yeah, well see sup later today, he had to take care of some other business. so yeah, maybe ctmike can give me his input since he had r's before. My brother in laws install should be done this week. building the box on thursday all day. should be a simple box and not to hard. make it as easy as possible.
