I have a '98 4-door blazer and I don't know what sizes the speakers are. There is a circular speaker in each door (6-1/2 or 6-3/4 maybe?) and two in the top of the dash (4x6?). If anybody knows their help would be greatly appreciated because I don't want to tear my doors apart until I put in new speakers. Thank you.

Rear doors are 6.5" and the front doors are oversized 6.5". The basket is bigger in the front. I am not sure about up in the dash.

 

Thanks

 

Go to http://www.crutchfield.com

Or go to your local Best Buy. Either place can tell you.

 

Actually from what I've read the factory door speakers are 7" speakers. Now obviously your replacements will be 6.5" in the front and 6.5" or 6.75" in the rear doors. The dash has very skinny 4x6's. The depth is like 1.5 inches.

FYI Crutchfield is a great reference for "what fits in my car". You can do a lookup there on sizes by vehicle and year.
