CD Changer plugs in here?

Ok, my gf just got an 88 accord and it has a 6 disk cd changer already hooked up and everything. I can't remember straight, but I thought my friend's hooked into his antenna plug in place, but I wasn't sure. I was wondering if hers is too cause she gets extremely crappy radio reception.

Kicker - Could it be that your friend had an RF Modulated Changer? Because that's the only kind of changer that works through the antenna.

Im not quite sure about 89 Hondas, but most the newer Honda Stock Stereos have CD changer control for Alpine "M Bus" Changers, that will plug directly into the back... with some sort of adapter cable of course.

Yeah, I thought it would have another way to plug in. But I can't figure out why it has such sucky radio reception, so I was wondering if it would be because the changer is hooked up through the antenna. And my gf doesn't want me to take things apart, so I can't look. :(
