The factory dash cutout speakers are a 4x6 unit. I have replaced mine with a JL Audio 3 way set up {6 1/2 in the door, a 4 in the dash, and a 1 aluminum tweeter in the dash}. This was a fun custom baffle that I fabricated and installd myself. And much better in the audio department. Erik
the speakers in the dash are 4x6s, the speakers in the doors are 6.75in. and the back speakers are 6x9's
4x6 in the dash and 6x9 in the rear
The 1998 Chevrolet Blazer dashboard speakers measure four inches by three inches. There is a dashboard speaker on each side of the dashboard.
As far as I can tell the front and rear speakers are 6-3/4 in
The 93 K1500 Blazer has 4 x 6 inch in the dash, and 4 x 10 inch in the rear.
5 1/4" I have the same year blazer and i just replaced all my speakers. At least it's 5 1/4" for the door speakers and i can't tell but there's places in the dash board for 4x6" speakers.
Dash = 4 in x 6 in Door = 6.5 in Rear = 6 in x 9 in
5 1/4 for the back doors and 6 1/2 for the front doors. I am not sure about the dash board speakers.
6"3/4 in the doors and 6x9 in the rear dash
The speakers i put in the dash of my 98 were 3.5 inch speakers!
The Door speakers are 6.5 inch and the speakers on dash board, I think they are 4.5, I believe.
The door speakers are 6.5" and the dash speaker size is 4."
