I read a lot of posts of people asking exactly what size the front speakers are because even though they are listed as 6 3/4 they really sit in an 8 in. hole and that i understand but what about the back speakers. I have heard 2 different things some people have said they replaced them with 6.5 speakers and they fit perfectly but some people say they are 6 and 3/4 speakers. I want to replace my back speakers and i would like to know what size would be a perfect fit has anyone here done that and have more information on it? I also have a 94 us gt celica with tweeters on the door frame and a factory 2 din cd/tape player if that makes any difference.

I replaced the back speakers with 6 1/2" x-plods. fit perfectly. the 6 3/4"s may fit in the back as well because it goes by where holes are placed within the speaker frame. i think you will be alright with either size, but i would recommend 6 1/2"s

i got a 95 st replaced with 6.5 fits perfectly >>
