Evening all.
I'm trying to install the above stereo into my car. I'm completely unable to find the setting to turn any of pre-amp on.
I have gone through all the setting on stereo but nothing there. I have read the usermanual twice now but still nothing. If i look at any other kenwood stereo there is options to turn sub on etc.
I've only done a headunit change from a fully working system with amps so I know the amps are all good.
on my pioneer stereo the option is there and simple to find.

Could anyone shed a little light on this.
