Convertible rear speaker

[Keycor]

1970 Chrysler 300 convertible. I need to replace the factory speaker that is located in the center of the back seat. If you have done this, please share with me what speaker you bought and where you got it? Thanks

It's going to depend on what you have for a radio. Some basics: Speakers And Power

For my converted radios (discussed in another thread) I use a Custom Autosound 6x9 dual voice coil speaker. It's basically a speaker with two smaller speakers in front of the larger 6x9 speaker. This let's me have the stereo left and right channels in one speaker. Sounds good too. https://garytayman.com/abante/dvc-3006

Retroradio also sells a similar speaker, but my experience with them was abysmal with two different speakers failing.

Thanks again Big_John. My 1970 300 is a convertible. Therefore I have 4 inch speakers on the left and right side of the dash. The right speaker was fairly easily to access. I have a shop manual which gave me instructions on removing the glovebox to access the speaker. The left speaker is going to be a more of a challenge for me. I will need someone that has experience getting into the dash to access that speaker. I have found pair of Polk speakers at Crutchfield's that look good. They are a two-way speaker with a tweeter. Nice and heavy. Also, again being a convertible I have the 6 x 9 in the center of the back seat. The one you purchased looks good to me. I will have to access it through the trunk according to the shop manual. The radio itself is with a builtin 8-track. Some one referred me to to Barry's 8-track in Prescott, AZ. I watched one of his videos after he rebuilt an 8-track AM-FM/8-track from a 1970 Chrysler 300. This guy seems to really know his stuff. Yes, he is pricey, very. But I love the idea of having a working factory 8-track. So, I will pursue that. He doesn't repair the unit, he rebuilds it with all modern components. I will even pay extra to get the bluetooth access. The new unit's power output goes from 4 watts RMS per speaker to 22.5 watts per speaker. This requires a need to upgrade from those factory speakers. Supposedly the sound is remarkably better. You can get deeper bass, more articulate highs and max output power. You have a choice of using the old connections or a new wiring harness. Keycor.

That's the same Aurora conversion that Gary Tayman does, so that's great! We have had a bunch of guys looking for 8-track repairs and I know Tayman doesn't do them.

To remove the rear speaker, you can get to it from the back seat. You need to remove the boot, that just slides out the side. Then remove the trim along the top with the black plastic panel. IIRC, there's some screws along the bottom. I don't have a pic of the back of the speaker, but it's pretty clear once you get the cover off. Myself, I take the seat out because it's easier for me.

The boot has been removed in this pic.

Assuming the dash structure of a 300 is the same as a Fury then you're going to need left and right dash speakers that are less than 2" and that is only because of the driver's side that has clearance issues with the clock bracing. Its actually not the depth only, its the magnet width that gets you. The edge of magnets hits first. So if you get a speaker that is narrow and shaped like stock you could go deeper..how much? not sure. The passenger side has plenty of depth.

If I did it over again I would use one of the neo magnet speakers and, if needed, trim the dash frame to provide the depth .

I had original AM radio in a 66 Polara 500 Convertible that I added a rear speaker and original fader switch to.
Bought 6x9 speaker from S&M Electro Tech online.
Be sure to get the 8 ohm speaker if you have the original radio. I also replaced the speaker grille while I had the seat out.

I actually put a Kenwood 6x9 triax into the factory spot in the back and drive it and another, in the trunk in a cabinet w a modest little 100 W Pioneer amp. This gets signal from a little under dash cassette player up front, w a Bluetooth cassette adapter in it. This stuff sounds a lot like many 1970s stereos, and leaves a bit to be desired, but its authentic to the era the stuff I'm running was made in.
