Thanks Thos, When I saw only 2 speaker connections on the back of my old Becker it stopped me right in my tracks. With all the helpful info on this thread I was able to continue on with my audio upgrade install. I completed it successfully. I replaced my front speakers with drop-in 3.5s from Crutchfield. The stereo was part of a $90 set from Pioneer (Walmart online) that came with 2 6x9s and 2 6.5s. I put the 6x9 in the rear. I now have much improved car audio. I had planed to put the 6.5s in the doors but, I don't think I need to. Thanks to all who posted on this thread.

Thanks,
