Hello before my sub and later my FS over my Pioneer 9600 to control and want to ask how to adjust that then? So the set on the radio works quite well only I don’t know what I have to set on the amp? Have two amps and a chinchleitung each. One for the sub and one for the (not yet installed) FS. Hope you can help me already Googled and not really found anything. Or do you know what to look for? Thanks already
