HI, I know that there are several entries on the subject, but somehow none of them have become smart. So far I have come: power cable from the battery to the amplifier. – Cable connected to the body. Sub and 2 speakers connected to the amplifier chinch cable and remote cable from the radio to the amplifier closed. My problem is: I have juice on the thing, but the sub and the speakers don’t give any sound of themselves!!!! Is 3 channel have a over on my amplifier 4 inputs for my chinch cable. 2 for rear input and 2 for front input. but have only 2 plugs on my chinch cable. Is my problem because I need n`other chinch cable, or did I forget anything else??? I don’t know any more, am grateful for every answer!!!
