Alpine type r problems
Monday, January 23, 2006 5:34 PM
I have an alpine type r 12 DVC sub hooked up to a V12 605 amp. The Sub is in a sealed box and is bridged down to 2 ohms. I cant figure out whats wrong with it. it just doesnt sound good. Anyone else have the same problems?

What are the box dimensions?

Do you have a link to the box?

How do you have the subs wired?

Are you running a stock deck?

What are the dimensions of the box?
Go measure it when you have time.

Also...where did you get the box? Alot of pre-fab boxes are build with 5/8" MDF or particle board instead 3/4"...which causes resonance and can hurt sound.

your problem is the prefab box, aiwa deck, and bad tuning. Fix all 3 and you will have good bass, there is no QUICK fix to this problem. (make sure the box is proper demensions.)
