View Full Version : Mounting radio speaker

June 24th, 2013, 02:30 PM
I'm having the radio upgrades to Fm-digital with an iPod input, I bought a replacement dual speaker set up through LMC (same as others I suspect). Iím trying to figure out how to mount it, they donít give you any real help. I have the original factory radio brace and will dry fit the radio in the dash to see what she looks like and what kind of room I have, I suppose I can rig something up, but would rather try and do it correctly. Iím not the first ones to have the issue. Anybody else did this yet?

If you are using a replacement for the original speaker, there is a mount that the factory used to attach the speaker to the underside of the dash. If you do not have it you will have to fabricate one. I guess this is why most folks purchase kick panels with the speakers already in them. Hope this helps you out.

O have the OEM mount but will need to find a replacement speaker the aftermarkets unit looks impossible to mount at least right now? Unless I glue the **** thing in!

OK I dug out the OEM speaker mount and can understand where that goes, but I will need to buy a OEm factory speaker IF I can't use this part to hold in the NEW after market dual set up?

I am looking for a factory under the dash speaker mount for my 1966 GMC Pickup, if anyone has one that they would like to sell please contact me.

Left is factory speaker bracket for '64-66 GMC cabs for the factory 4x10 under-dash speaker. The rubber tip sits on top of the ashtray housing. Right is the factory speaker bracket for '60-63 cabs which is offset to sit on the ashtray housing. The dash location of the ashtray, heater controls and such was changed between '63 and '64.

Arthur, thanks for posting the two pictures, my 1961 Suburban has the proper radio bracket, I need one for my 1966 GMC P/U.

I'm hoping I can dins a dual cone speaker to fit the hole. I wear hearign aids and DO like listening to some tunes.

Hey Jake, I have seen stereo dual cone speakers sold to fit these trucks in some catalog they sent me. I will see if I can find it. I need to get one also. May I ask how you are getting to FM in an AM chassis? I am planning to do the same. Factory correct looks, but FM from the speaker. Greg Mead

I made my own brackets. One under the dash attached with bonded T-nuts that held two speakers (I think they were 3.5" dia speakers). Then I also made two additional speaker brackets, one for the drivers side and the other on the passenger side, which held one of the same speaker on each side.

I posted pictures of my install on this site several years ago. Let me know if you're interested or have trouble finding them. Stereo - Secret hidden installation http://6066gmcclub.com/forum/album.php?albumid=30

you may be disappointed with your new dual cone speaker if using the factory radio to power it - I bought one from LMC same as you did, and it sounds worse than the original because of the weak radio wattage or just because it sucks - not sure which, but I wont be buying any more of them - hope you have better luck than I did!

I did't have factory mounts. What I did I used two long machine bots # 8 or 10s through the speaker grill. Center the best I could slots in speaker had to offset by one slot.this aligned the holes in speaker to radio side of dash. Windshield side I used perferrated band attached to the top screws on the wiper body. Nice tight. No vibrations with the after market radio. Fits the dash opening great. Has a GMC ON FACE
