Speaker size

[t3intercooled]

I know my 87 GN has 4 x 10 speakers in the rear, now what sizes are in the dash, and doors. I need to replace them and not sure what size to get. Any help would be greatly appreciated. Thanks.

3 1/2" in the dash and 5 1/4" in the door. For the dash the tweeter cannot protrude too far out or the dash panel will not fit right. For the door you can cut the back out of the plastic piece the speaker fits into, which will allow you to use a speaker with a deeper/larger magnet. HTH
