Currently have 2 x 12" KFC-xw1225db in a 80 lt box tuned to 25 hz in a Custom VY commodore. I wanted to take away the box and turn in into an IB setup? Spec's for Sub are as follow...

Levc. 4.7

Sd. 0.0312

BL. 17.9

Vas. 113lt

Qes. 0.37

Qts. 0.35

Currently have a mono block amp running the Sub's.

Kenwood Excelon KAC-X811D ( Im sure its set to 1 ohm )

The current setup was done by Autobarn and its no good!, will the IB setup work well or any idea's on a new box?. I spend a huge amount of money for this setup 3 yrs ago and no good. Any help would be great. I modeled the sub's in win isd and it came up with 120 lt for 1 sub?.

Any help would be great. Thanks in advance.
