I have this kenwood stereo receiver kr 795 It powers up but no sound, please help?

ok you have power so the problem is that the speakers are not connected right you might have to connect a speaker at a time so that you can test the speakers too , always positive from the speaker to positive to the unit negative from speakers to negative to the head unit .

i had this problem before and it took me a while to figure it out by my self that i done a mistake lol i wasn't born a pro nut i intend to become one
