HELLO

I would say that it is perfectly OK to replace the speaker with a new modern one. Measure the aperture (hole) and also get a reading from the old speaker as to the impedance or OHMS and the power handling. This is important as you don't want to damage your new speaker.

When you have the size, impedance and power rating you can then search for a new speaker. If however, a speaker of that period is what you want, there are quite a number of vintage radio websites who will be happy to give you advice from fellow collectors. It MAY even be possible to have your old speaker reconditioned. But being honest, I'm just guessing on that one.

2007 cierra ,my radio cones on but not putting power to speakers except to 1 front speaker and it has almost no sound ,up full and very screechy . do I need a new radio ?


Sounds like a wire is shorting out, probably in behind the stereo, but more likely in the back where the speakers connect. Check for something shorting out or a wire grounding out near the speaker.
You can trace back from there.
Other than that probably is the stereo.

I got a 91 chevy pick up with a cilfford, the radio works but hardly any sound comes out of speakers. I got a new radio and its the same. All speakers play buy sound is very low. I was told it was do to...


posted 6 times.
run new wires from new radio to speakers
or bench test your radio (easy) with your speakers.
if still low the speakers are bad or just dirt cheap , car speakers.
try new speakers, if weak now the wires are bad, try new wires
id still weak the radio is bad. (or just a cheap radio)
and define weak, to me most radios are way too load.
but to others, all are weak until 1000watt amp is added.
weak is a relative term. as is hardly any.
do not quote persons guessing, its just a wild guess. they can see car either, do the tests your self and find TRUTH.

to bench test, (modern way)
1: 12vdc 1amp power pack, or battery 12v. and ground.
2: connect up USB mem,. with some mp3s. on stick.
3: connect one good speaker (KNOWN GOOD)
to one of 4 speaker lines. (2 wires)
4: push play, does it sound good, yes, move to next speaker port.
ok , the radio is good. so
try it in the car, is it now low volumn
yes, then move that test speaker to the car speaker that is low.
still low, yes, then the wiring is bad.

easy huh?,,, takes only , a test speaker.

if no usb use, cassette, if no that , use CDDA disk( store bought real)
if none of that us the radio to test. connect a test antenna.
tune in Am or fm. bam.

Why is there no sound from my speakers but the radio is on


easy check to carry out ,borrow a speaker that you know works, if you remove one from another vehicle make sure ignition is off when taking speaker out, take a speaker out from your vehicle ignition off , the door speakers are usually the easiest to remove,plug in the known good speaker to your vehicle turn ignition on then radio, if you get sound then the problem is with the speakers but very unusual for all speakers to blow at the same time unless there has been a power surge through the amp. if no sound still remove radio and make sure the wire connectors are pushed home securely if they are then it's most likely the radio is not working will need replacing as a repair can be more expensive than new

My radio lights are on but no sound, what do I do??


Try to mess with the fade and balance. It's possible you have one or two bad speakers and the radio only has the bad ones getting power.
If you have a remote or can borrow a remote (or have steering wheel controls) try to change the volume with it. Your volume button could be bad on the radio.
Something else you may want to try; first make sure you have your unlock code for the radio! Then remove your radio from the dash. This will take some time but be patient you don't want to break anything. Once out unplug all the wires and wait about 10 min's. This will sometimes reset the radio but if this works it will most likely go back out in due time. This will give you time to get a new radio.
You could try to pull the fuses to the radio instead just make sure you get them all or disconnect the battery for a while. These two may not do anything sense some pcm or ecu have their own battery back up and the radio will use it for it's memory if it can.
Another way to check the speakers is to do a oil lift reset. If I remember right; you can do the reset though the radio and it should chime over the speakers.
Most likely the channels have burnt out and you will need to replace the radio. Stay with an OEM shop ebay.

I have a 1947 radio but the speaker is bad can i replace it with a new speaker or do i need to find one from that time frame?


You might find it diffcult to find a 1947 speaker. All you need to do is find out the OHM and the Watts of the speaker and match it up. The watts level of that time won't be very high, so I don't thank you will have a problem with that, however the ohm level may be a lot higher than many modern speakers.
Remember a speaker rated say 15ohm can only be replaced with the same or higher value.

Front speaker just quit


I doubt there is a fuse. There are only four possibilities:
1. Speaker blown. 2. Wire slipped off of speaker terminal. 3. Wires from radio to speaker is shorted (not likely). 4. Radio is bad.
My guess is speaker is bad. Try pushing the cone inward while the radio is playing to see if you are getting any sound from the speaker if you do then the speaker is bad and needs to be replaced.
Good luck!

Hello there:
the shielded coax rgu-45 series is probably the best one for this application also if you run the radio to a different fuse or u can also get a surpression filter that goes on the coax line I own a WL9000 KW. i had the same problem untill i got the filter installed at a loves truck stop in texas and no more problems since ok?
drive safe and best regards mike (warner transp.)

I would like to help because I have about 10 of those radios, and one by one the speakers are binding up just like yours did.

However, the speaker is built into the frame of the radio and the Manufacture does not sell replacemt parts for them. In addition, there is really not enough room to mount a replacement speaker of similar dimensions, and I am would be quite capable of doing it myself if that was possible.

I hate to face the fact that my radios have seen better days unless I want to use a speaker mic and I don't because the extra cost, size and weight are not practical to save radios that I can replace with new for just a bit more.

They were great radios, and Motorola should be ashamed that they don't make after market speakers. I'm sure they just want to sell new ones to us.

By the way there are no 'WIRES" to the speaker, it makes contact with the board terminals when you re-assemble the radio.
