QuestionQUESTION: Installing a new Motorola Reverberator coil for rear speaker on a 1966 Dodge Coronet w/AM radio. (Motorola part #1A64030B01) Other new OEM parts are being used including dash control switch..wiring harness.. mounting bracket and original rear speaker. Since an original reverberator assembly has not been found to rebuild or use as an example, my question is...Can power IN to reverberator coil from front control switch be routed directly OUT to rear speaker or are other electronic components/items required with the coil for proper operation?
As you know, this kind of sound technology only existed for a few years.... but there is nothing else quite like it and I would appreciate any information you could provide.
Thanks
ANSWER: Yes, I am familiar with the spring reverbs. They have an interesting sound quality but have been replaced now days with digital reverb circuits.
I am not sure I understand your question about installing the spring in your car but here is my take on it: The delay unit is not able to drive a speaker. That is there must be an audio amplifier at the output of the reverb to boost the power to the speakers. Most of them had speaker input to drive the spring, so you need to look at the specs on it if you can find them, but if there are no electronics in the reverb for amplifying the input than it is driven from a speaker output. The power is lost in the coil so that is why you need an amplifier at the output to drive an external amplifier.
Does that help? Let me know if I missed the mark.

QUESTION: I appreciate your prompt response...you are exactly on track with my question. I have some additional info & picture of reverb coil that might help:
1. Ref: '66 Dodge Service Mauual...power to Reverb control switch is provided directly from the fuse block via a wiring harness which also routes on to radio - front speaker - rear reverberator and speaker. When the switch is pushed in...FADER control is provided to rear speaker. When the switch is pulled out...power is provided to reverberator and time delay is controlled by turning same knob.
2. A picture of new Motorola coil is in attached file.
Is it possible that this application provides sufficient power to drive rear speaker?
AnswerThanks. Haven't seen one of those in a long time! They are classic vintage stuff.
No, the spring will not provide any power; it is a low level device operating on just a few milliwatts in and out. But the system it is integrated with should have the power necessary to drive it and get the signal out of the other end. What it does is mix the delayed output of the signal back into the original to give it the echo or reverb effect. The electronics to do all that are part of the system that it goes into.
If you are installing it in an aftermarket system you will need to feed the output of the reverb into the amp feeding the rear deck speakers. Something like that.
Good Luck.
