Is the angle of the back seat inside trunk of coupe same as sedan?
 

Is the angle of the back seat (inside trunk) the same for 2 door and 4 door E46?

Reason for asking is my friend is going to make a subwoofer (in cf)
for me but he's 100 miles away and he can measure an E46 sedan.

Thanks

Don't know for sure, but my gues is that they are both the same.

I need to be sure :D

Step 1: measure yours yourself
Step 2: Have him measure the Sedan
Step 3: Contact him with some device (phone, email, ect.)
Step 4: Discuss your findings
