Sorry to burst your bubble but you have bought an inferior product. The one you bought has 2 pre outs and 3 band equaliser. The other two had five band equaliser and the jvc had 3 pre-outs.
I am very much happy with it.
Also i didn't want to spend 14k for HU.
This gives correct bass, as how i need.
Will post a pic tomorrow.
In the manual they have clearly mentioned 3 pre-out.
JVC in similar range has 2 pre-out.
He also showed me Alpine 3 Pre-out, which was superb, but was single DIN.
