Re: [Chrysler300] stock radio 2 speaker hook up?

The model 348 AM radio speakers can be configured three different ways.

 

1 - Front speaker only - In this configuration, the front speaker connects to the brown and yellow striped wires and the jumper is installed between pins 3 & 4 on the four-pin rear speaker connector on the back of the radio.  The ring knob on the right of the radio, around the tuning knob, rotates, but does not fade the speaker output.

 

2 - Front & Rear Speaker (without reverberator) - In this configuration, the front speaker connects as described above and the rear speaker wiring connects to the four-pin rear speaker connector (no jumper).  Front to Rear speaker fade is controlled by the ring knob on the right of the radio, around the tuning knob.

 

3 - Front Speaker with Rear Speaker and Reverberator - In this configuration, the reverberator unit is located (on the convertible) behind the rear seat and below the top pump (factory).  The on/off switch and fader control for the reverberator is the accessory knob below the ignition switch that is labeled "rear speaker".  Pull the knob out to turn on the reverb, push it back in to turn off the reverb.  Rotate this knob to fade.  One brown speaker wire from the radio will be attached to the front speaker, while the other is attached to wiring to the reverb switch.  The four-pin rear speaker connector in the back of the radio will have the jumper installed, same as front speaker only.

 

Sounds to me that your convertible came from the factory with AM radio and the reverb unit.  This can be confirmed on the body data plate if it is coded both H2 (AM radio front speaker only configuration) and W6 (rear speaker with reverb).  Wiring schematics for the radios, reverberator, and rear speakers can be found in the 1964 factory service manual, pages 1-15 through 1-19.

Subject: [Chrysler300] stock radio 2 speaker hook up?

 

Hi all,
I have a 64 convertible with a model 348 Am radio. Had one front speaker. However, the car can be configured to handle a front as well as a rear speaker. Which is what I would like to do. This leads to my problem. I have speaker wires running from the rear to the dash area. I have speaker wires the for the front speakers coming right of the radio. Brown "lamp cord". Now for my confusion/problem! I have been told that the model 348 has an internal fader. I believe I have found it on the back of the radio as a 4 pin phenolic plugin. Presently configured for one speaker only( U shaped pin in lower plugin holes) However, I have what looks to be a stock chrome knob on the lower part of my dash( were my right knee would be while driving) that reads " speaker". I believe this to also be a fader. Anyone configured a 348 for front and back speakers? Any help, ideas?

Thanks for any help.
