Type R - WTF?

Im thinking theres a leak in the box. Do you hear air escaping?

If your subs are moving alot and it isnt hitting at all, then its your box. Like Defcon said, check for leaks. I just think it isnt big enough.

I just went out there, and didn't hear any air, but that doesn't mean that is not the case. I guess I will pull the subs out, re-seal and see what happens. I guess everyone agrees that is something with the box? Size, Air leak, etc...

Bigbang, how is it not big enough if you have 1.75 for 2, and I have two seperate sealed boxes at .995 ea. That is almost 2.0 cu ft total.?????

2x 12" in a .995 sealed box?? that cant be right... alpine recommends .78ft3 PER sub.

you dont have enough volume in your box...

take a piece of paper and slowly move it around the edges of your box with your system up. any air leaks will blow it around.

how bout some pics?

1cf per sub is OK,do you have your amp on LP?

whats your HU set at,60-80hz?

Is the box sealed up well with caulk?

do you have a good seal from behand the subs as well?

I tried the type-r 12 w/ the Alpine MRD-M1005 (1000W) in a sealed box, and it licked balls. I bet the 2cuft net ported box tuned to 32hz is 3-4x louder.

Port them, its the only way to go, but be prepared to eat up lots of space in the trunk... you need almost 6cuft to port 2 12's.

take the sub out and get an air compressor and shoot the air at the seems and see if you have any leaks. if not get a tcab box because they are the only ones who know how to make quality boxes.

I am going to try the paper trick when I get home and see if there are any leaks. If there are, I will look to fix those and see if that changes anything. If that is not theproblem, I think I am going to look at getting a ported box for 'em. Thanks for all the feedback and help.
