Speaker questions?

[Deercreekfarm]

1991 Suburban v2500. Haven’t had a chance to yank the dash yet but I have a question on the speakers; I know there are the two side speakers (3 1/2” round) but is there a third center dash speaker? The dash has the speaker vent/holes in the center of the dash.

I’ve ordered the new radio, 50’ of 16 gauge wire, electrical connectors and the two rear 4”x10” speakers and like I mention the two front 3 1/2” speakers just trying to figure out if I need to order a third center speaker and what size if there is one. I will be installing this weekend and just wanted to have everything on hand before I jumped into the project.

Thanks for any info.

The center hole is for a 4x10 speaker if you have a mono radio   AM only or AM-FM non-stereo

Thanks for the clarification!
