Stereo install help

Hi,
I just bought an 87 GT convertible 2 weeks ago and I love it. I need some help from all you Mustang experts.
My 87 GT came with the factory EQ. I removed the stock unit. I have a Kenwood head unit with the factory harness adaptor. I wired in everything and I have no sound from the speakers. I know the head unit is good because I unpluged the Kenwood I have in my truck and plugged it into my truck and it works fine. I would guess that the EQ plug has something to do with it, but what do I have to do to make it work? Please help.
Thanks
Frank

Ok. I have the whole interior out, so that makes it a lot easier. The amp is mounted right behind the console to the hump. I unbolted & unpluged it. Then I found the other 2 connector that the radio install harness plugs into. Now I have rear speakers and dash speakers, but no door speakers. Any more advice on gettin the door speakers working.
Thanks
Frank
