I'v got a weird problem... and I really can't figure it out... I'v tried pretty much everything possible...
I have a sony mp3 player CDX-F7705X.
this cd players schemas are here:

and a pioneer gmx572 amplifier which is here
on the back of the amp there are two little places where u can stick in the rca pin cord.. or whatever those wires are called... but we cant see those on the amp's picture

And 2 subs in one box...

I'v connected those 2 cords to the cd players "Audio Out Rear" connectors of the image... and then connected the System control of the amplifier to the ignition switch of the cd player. The subs work and the cd player works but the subs can't be controlled from the cd players "Sub control" Option... instead the subs are controlled along with all the bass of the car including rear and front speakers... and the sub control option doesent do anything..

After that i tried connecting the rca pin cords connectors to the "Sub out (mono)" and then just like before to the amplifier... This made the sub control option in the cd player work, and the subs were controllable with the sub control and the bass of the speakers were controlled with the bass.. the only problem, was that, the subs would give a kick everytime i changed radio stations or even change tracks or just put the key in the ignition without the face plate and the subs would go BOOM, (a little short hit) which would happen often...

i tried putting the AMP REM wire of the cd player with the System Control wire of the amplifier but that didn't do anything... with both setups...

i'v also tried putting the rca pin cords in the "BUS AUDIO IN/ AUX IN" and also in "AUDIO OUT FRONT" and it gave the same results as with the "AUDIO OUT REAR" ....
i dunno what to do anymore... someone please help =(
