« on: January 14, 2018, 03:34:57 AM »
Hi.
Planning to replace the original stereo - speakers in the rear shelf of my 67 Eldo
Car is stored for the winter, ( winter ends in Stockholm mid-april ) so I can not check this "live".
Anybody out there knows what speaker - size to use ?
Cheers

Here are pictures of one of the speakers I removed from my 67 Eldorado last year. I believe this is an original speaker.

In American terms, the Eldorado uses the classic "6 x 9" inch oval speakers. The problem comes if you aren't seeking out exact duplicates for replacements. The original speaker (by my measurement) is 70mm deep, from top of speaker gasket to bottom of magnet.

As usual, I found out the hard way that you can't simply plop the vast majority of modern 6 x 9 speakers into a 67 Eldorado. This is due to the torsion springs that hold the trunk lid open. Those springs run just beneath the bottoms of the speakers with very little clearance. You can make a tiny bit of additional clearance by moving the torsion springs to other positions, but such moves won't buy you much additional space. Plus, moving those torsion springs takes more force than you might think!

You'll also notice the (torn) fabric over these speakers. Unlike most current aftermarket items, the original speakers didn't have high-frequency driver elements that pop up in the middle. From the factory, there is no slack above the Eldorado speaker because the package shelf acts as the speaker cover.

I bought the thinnest modern speakers I could find (not outrageously pricey) that still sounded way better than the originals. The center sections in these Kenwoods protruded as little as possible among the speakers I could find. And the magnets were no deeper than stock.

To handle the small protrusion above the package shelf, I had to cut out the strip of metal that went across the face of the speaker. I really didn't want to -- this is the only place on the car that I've cut or drilled original metal -- but the tradeoff was worth it for me.

Then I made a spacer that fit underneath the top-most layer of the package shelf to keep the speaker unencumbered. There's enough slack in the way that the package shelf is assembled that my spacer didn't cause any problems. Now my package shelf sits just above the mid- and high-range drivers in the centers of the speakers.

Also, be wary of the screws that hold the speakers in. In my case, somebody had been there before and messed up some of the screws. (What a surprise!) I had to clear out most of the original screws and put in new ones to get everything back together.

This should be an easy job, but the Eldorado-ness of the situation might cause a few unexpected delays. :-)

Good luck!

If you are replacing speakers, I would recommend www.turnswitch.com as a great source.  They supply the correct speakers for our cars.  You need to stay with a  10 ohm speaker if you are keeping the stock radio.  Most modern speakers are 4 ohm and these will damage your radio's amp section.
