Howdy, I am not knowlegable at all about the back of CD players. Sad, I know. I'm looking into getting a new one and I see some wires on the rear of it that I don't know what they are for. Someone help me out please. I'm looking at this one right now : http://www.cardomain.com/item/JVCKDAR870?vq_id=none
I am wondering whatn the only 2 (technically 3 wires cause one is bundled into 2) wires are/do. I know this is prolly a dumb question but this is one of the ways to find out. TIA.

PS - It's picture number 3 on the site.

Big black one is Antenna - the corded RCA's are probably Aux in. Round black connector in the radio is Changer control

JVC decks are a good bang for the buck. I bought one for my GF's car(not this one tho). easy to use, good looks.

Enjoy.

Thanks to both of you!
