I think this been covered before but I know there is a spot for tweeters in the back corners and above the back window im assuming came on the top of the line 4runners, but i cant find where you would mount them, is there something im missing? is there mounts for these speakers?

 

No, You will have to splice into the wires at the speaker (You may want to include crossovers) in your side pannels unless you run a new set all the way front to back.

 

yea i know they would splice into the speakers thats no problem, and i would be running crossovers too. I just dont know how or where these tweeters are supposed to mount, and if anybody knows why there are 4 speaker grilles in the panels in the back corner, is there supposed to be another set of tweeters there too or a smaller set of speakers?

 

Yes there are mounts that go up there, that hold a midrange tweeter combo, I had to salvage one out of 95 the brackets and the matching roof bar to install into my 90. Just look at my build thread in my sig. and you'll get an idea. As far as the grill opening in the corners I didn't really see any mounts for tweeters behind there besides the 5.25's that go in there boxes. If you were to install a set in there i think you might run into a sound issue as far as rearfill is concerned. You can see in my pics I installed a dome midrange and modified the upper panel and installed the matching set of tweeters to go with that setup. Hope that helps you out.

 

Pictures of the vents you're talking about might be helpful, but I'm pretty sure you're looking at part of the cabin venting system.

The other spot for speakers is in the rear pillars IIRC. Should be some threads about em. Two above the gate, two in the rear side, two in the passenger pillars, and two in the dash.

A quick search turns up THIS thread and this photo. which shows the mounts and wiring. Which presumably plugs into one of those connectors in your photo of the left side.

 

I didnt think of a venting system, that must be what the sppeaker grille lookin part is in the top rear corner. So speakers go above the rear window than, now i just need to get my hands on some mounts

 

Salvage yard, self service one if you have one. Bonus you get to see where they actually go
