Questions on 803 upgrade

[sid550_0]

i switched a 613 for an 803. My question is about the center channel. I found the speaker wires attached to fake speaker bracket and attached an oem speaker for now. I plugged in the green and the small grey plug into the back of the 803. I taped the old speaker plug and wires together so they would not rattle around. Only problem I have is very poor FM reception. Did I miss something? There were only three plug ins off the harness. I did not see an extra wire with a standard style plug for the antenna. Thanks

The antenna doesn't use a "standard" style plug. It should be a grey plug with two leads going into it.
