Hello i have searched numerous things and i need alot of help. I just bought a 2004 STI and of course it didnt come with a radio. Carmax told me it had one in it and it was prewired for 4 speakers and a head unit. I found the Harness for the head unit but i cant find the speaker wires anywhere in either door. Does anyone know where i can look. There doesnt look like there was ever any Speakers in the rear doors because i see no screw holes. I also what size are the speakers i have heard 6.5 in front and 5 1/4 in the rear then i have heard 5 1/4 in the front and 4 inch in the rear please help me get some tunes thanks. If anyone has pictures or anything that can be helpful i would appreachiate it.
