Mono to Stereo

[jstaples2]

During the re-do of the interior I wanted to finally have speakers in the dash. The original speaker was a 6x10 and was trashed, so I went with 2 5x5 speakers.

I had to make a couple small brackets to get the 2 speakers to tie together and fit into the stock location. I realize that both speakers are side by side and essentially negating any true stereo sound coming from the dash - but in any case I wanted speakers in the front and didn't want to wire up 1 6x9 in that spot.

Great! So what happened then? Was it better?

I did the same in my Satellite few years ago...
The sound is clearer but with both spkrs next to each other
the separation is not so great...
But in that car who cares ....

This is a very common occurrence for owners who do not want to cut up their dash. They do sound better than regular Mono. If you look at most radio shops on the web you can find a bracket to do this for any car.

Also if you can hide 4&1/2s in the kick panels, add bass blockers to the little tweeters in the dash. It will make the sound a bit better.

No one does the ole 6/9's on the rear deck anymore or is that taboo ?

I was assuming they already had the ole 6x9s in the back deck. Adding some 4.5" in the kick panels to round out an install consisting of the 6x9s and the smaller tweeters in the dash would be the way to go.

Another option is to find the dash speaker grilles on 68-70 B body cars that came with stereo. These were metal grilles that sat on the top of the steel dash and i believe used 3" tweeters. Sure you gotta cut the top of the dash sheetmetal, but it would give a factory look. If i had a 68-69 C and it wasnt a super rare car this is the setup i would use in the dash. They sit up because the dash was stamped flat, and as an add on its a surface mount. Plausable as a C body option?

I cut a piece of thin MDF to replace the 4 x 10" speaker in my 300.

View attachment 112771 Heres what i did for my A body. Could do something similar on a C body. I used .125" thick aluminum sheet. Sized for Dual 3.5s didnt have a hole saw big enough, so chain drilling the holes was a *****.

 

[jstaples2]

wow, beautiful! Puts my little brackets to shame!

 

[Moparmat2000]

Nah. Yours look fine. I'm an aircraft sheetmetal structures fabricator by trade, that gives me a leg up on some of this stuff. You should see my woodworking though, its pretty awful. I build everything out of metal, and if its something i can weld up, all the better. More dimensionally stable. lol.

In your defense though, the way the grille is on yours with the built in studs, i probably would have built a setup the same way you did. A bodies are a bit different where the speaker mounts to the metal frame, and that screws to the underside of the dash, thats why i had to make the plate.

Hello how much depth is there in a 1969 new yorker? can i just buy 4inch speakers and mount them in a plate like this?
I was thinking of mounting a composet, so with detached tweeters i can mount in the corners of the dash for a better stereo sound.
Anybody knows what shape hole the dash of the 69 new yorker has?
Are there plates for sale?
do they mount from the top or from the bottom?

It may help if the speakers were tipped towards the outside of the car so the sound bounced a little

Hello, do you have a mold or exact drawing of the mdf plate you made?
can you share it so i can build mine?
what is the available depth for the speaker? i see you speakers mounted to the plate, if that's no roblem i will have no problem also.
Is the plate mounted from underneath or from the top in the dashboard?
any vibrating of the dash when you turn up the volume?

I just made a template from a piece of file folder and laid it on the MDF. I don't have a drawing. The MDF came from a scrap pallet.

The MDF is mounted from the top.

There's no vibration or any issues like that. I used the MDF specifically because of that. Most speaker boxes are made from MDF because the density of the material tends not to vibrate.

 

[Ludo]

does anybody have a template, or can anybody make one using an original speaker?
I would like to make it before i go to the car so i can start installing it right away when i get there in May.
thnx Ludo
