4 x 6 - I just went looking for them this evening at Circuit City.
Driver side front seating area, under dash, left of steering column, mounted on bracket.
a 1991 buick skylark has 4" speakers in the dash and 6x9's in back
they are 4x6 rear speakers are 6x9
rear speakers are easy. open the trunk, look under the speakers. on one side of the plastic ring surronding them, their will be plastic nuts. loosen these and slide the ring off the other side. booya, there ya go :)
3 1/2 inch
Take it to Best Buy and have them switch out the speakers. That's what I did.
Yes, they can be replaced. According to Crutchfield.com, the front dash speakers are 4" x 6".
Its located behind the dash on the passenger's side.
The speakers i put in the dash of my 98 were 3.5 inch speakers!
4 inch in dash 5/1/4 in doors 6x8 in bCK
Flasher is bad. to replace it it is under the dash at the back of the steering column.
You have something over the sensor on top of the dash that is blocking the thing from working?
