P.s. My Amp is a Alpine PMX-F640.

I also have a 2 channel Alpine Amp I intend to use for the Subs.

Spent nearly 2 full days ripping my car apart (Boot and back seats out etc...) to install the Alpine H650 processor and although the rear speakers are difinitly improved since being fed with a full signal, having to use the Alpine remote to controll everything is just hopeless!!

I've calibrated the H650 with the HU volume at various levels and then tried to alter the volume via the OEM HU and it instantly distorts heavily and quality is greatly reduced!! YOU DEFINITLY NEED TO LEAVE THE HU VOLUME CONSTANT, despite what others have claimed. Also the volume of the PDC (although working) is very low (too low).

As a result the Alpine H650 processor is coming out and I am going to try the Hi-Fi coding route again!!

So again an answer to my previous post and details on who can carry out the Coding would be greatly appreciated!!
