Dash Speakers

What can ya'll using for dash speakers? I saw a post somewhere where a 4 inch will fit in the corners where a 3 1/2 in is from the factory but can't seem to locate it now. Are any of you running a 4x10 in the center or did you fab it up to put something else in there? Not looking for awesome sound, but the 28 year old factory speakers are sounding a little fried so figured I'd replace them when I take the dash pad off to install a cover.

4" will fit but you may have to trash the factory speaker brackets and cut up your dash. Most of the aftermarket 3.5" speakers will have a tweeter that protruds about 1/2 to 3/4" above the speaker. This may make your dash bulge, I have (2) sets that I am trying to figure out for this use: Infinity REF3012 and Polk DB351's. I have been working on a mount to under mount these in the factory 4x10 opening in the center. This should work with all of the dashes from 73-87. I got the idea from a post on here last year. One thing to note is the actual width of this opening ( 9.75" long by 3.75" deep). I am figuring on making a 3/4" plate out of plywood that may be roughly 12" wide x 4.5" deep. Hope this helps but, PM me if you have questions. I can shoot you some pics of what I am talking about

Re: Dash Speakers

Here is my setup, I have 4" mb quartz all the way across. When I ordered the speakers they came with an mount for 2-4" to fit in the middle. The 4" does fit in the side holes but does not fit flush like stock but you still have room under the dash pad where they do not hit. you could make them fit flush but will have to cut the dash, I opted not to. This is not the best picture but you can see where mine are, I cut holes and installed the covers b/c the factory dash is covered with leather. I don't have a pic of the speakers with the cover off but it will be coming off in a few days and can get one then if you would like.

Re: Dash Speakers

This is what i did. they fit fine, however like ecu pirate said my dash does slightly bulge on the passenger side. That may be partly because it is a reproduction

Re: Dash Speakers

For my '88 I just used 3.5's in the factory brackets. It's OK, but I would like to ditch them in favor of something larger in the kick panels. For my '77, I mounted dual 4's in the center opening. The frames were large enough that I could bolt the two together and then mount them to the dash. I like that setup.

Re: Dash Speakers

I'm going to get a dash overlay, and the factory speaker grill areas in the dash pad are absolutely trashed (cracked, split, disintegrating). I'll probably put 4" in there and wallow out the dash pad to get it to sit down like it should. Anyone see a problem doing that?

Re: Dash Speakers

i did 4" kickers all the way across i had to make a bracket out of some abs for the middle but the sides fit fine. I did have the glass out when i did it though. i think it will be really difficult to do it with a windshield in the way

Re: Dash Speakers

what i did to mine is flip the bracket upside and instead of puting them on top of the dash like factory i put them under the dash. it's hard to explain but if you can picture it in your head its not hard to do. it only took about 45 min to do. what it will do it will give you about 1/2 to 3/4 inches more clearance.
also i used the factory 3 1/2" speaker.

yeah, I'm in the same boat. I would prefer to put a 4" in there, but I want it to look ok without having to do a bunch of modding on the dash.

Re: Dash Speakers

I went to the local Pick-n-Pull after work today and scores a locking dipstick, heater control, sportbumper licence plate lamp, and 2 front speakers with brackets($22 Bucks). It was nice the dash was ripped off. Im going to see how the 3.5" compare to the 4" speakers for mounting. Under the bracket I noticed there is lots of room so opening the holes should not be an issue...

Try DapperDan. He mounted 4" speakers in the factory location. It looked pretty clean. I would love to see some pics with those factory mounts flipped upside down and installed under the dash. This may solve my whole problem so I can use my Polk db351's that are just waiting..........................

Re: Dash Speakers

A bump only because I've just gone down this road, and wanted to show what I came up with for others who are searching for the same thing:



Ditched the original 4x10 single speaker for a pair of old JBL 5-1/4" two-ways I shelved from a car I cut up eight years ago. Adapter made from a dollar store cutting board.

Re: Dash Speakers

I think you can also add spacers (nuts?) to the mounting areas to bring the speakers down a little and clear the dash pad.

I have 3.5" speakers in the kick panels - but just in a circular hole cut in the metal kick panel. The magnets are a close fit but they work fine. I made triangular wood speaker boxes for the rear speakers in the cab corners. Overall, my setup is OK, but I think if you can do the two speakers in the center that would be a nice stock touch. Being able to control the fade from front to rear speakers is nice, as well as left to right balance, especially on a long drive.

Re: Dash Speakers

I did 4" in the outers and 3.5's in the inner. As stated, the 4" speakers i got were a pain to fit. I had to ditch the bracket on the driver side and cut the dash to get the speaker to drop in. The centers clear the dash pad just fine how they are in the picture. THe passenger side 4" hits the A/C duct but its manageable.

Re: Dash Speakers

How is everyone wiring 6 speakers (4 in the dash and two in the rear) with a standard 4 speaker wiring setup?

Re: Dash Speakers

In my Suburban, the factory head was replaced with a unit that had four standard speaker outputs (which I ran two to the 3 1/2 in the dash, then two to feed two powered subwoofers under the bench seat). The new head also had four RCA out puts that was used on a 4 channel amp that was used to power 6.5 in the kick-panels and the 4x10's in the rear.

Initially I tried tying the 4 dash speakers together in the front, and ran the rear channels to the 6x9's behind the seat. Head unit didn't have the power to run them that way, got all kinds of distortion on the fronts, so I unhooked the 3.5's in the middle.

I figure eventually I'll add an amp, run them something like rideair said he's done.
