SOURCE: i touched two speaker wires together and amp will not respond

That is a very nice amp . Try not to touch (short) those wires together. But yes, the amp has protection and is shutting off to protect it.

SOURCE: Static noise from Front Left Speaker

It would probably be with the speaker. That is easily checked by simply unhooking the speaker and running the test again.

Loud speaker static from 2002 Mitsubishi Eclipse when the car is off. It drained that battery. I tried pulling the radio fuse but it was still making the noise. I had to disconnect the battery to g


The fuse might be built into the cable to the lighterand/or radio. It's called "fusable link", this type of fuse looks like a cable. Or another type of fusable link might be in the fuse box under the hood near the firewall.

10 years and first problem to repair. When you turn on and select DVD or any other selection a very loud cracking noise comes through right speaker only. So loud (with volume tuned off too) that I fear...


I think your receiver is damaged.

Try this.

Mark the speaker wires on the back of the receiver. label the speaker connected to the left channel "Left" and the speaker connected the the right channel "Right"

Also pay attention to the polarity (positive an negative) making some type of marking on your speaker wire so you can reconnect them correctly.

Disconnect both left and right speakers.

Connect the speaker wire that is labeled "Right" to the receiver's left speaker connections only then turn your receiver on.

IF the loud noise comes back, this speaker is damaged. I am guessing that the speaker is fine.

Now connect the speaker that was labeled "Left" to the receiver's right speaker connections and turn the receiver on.

IF the loud noise comes back like it did before but now playing through the "good" speaker there is a problem with your receiver.

If so, your receiver is 10 years old. Isn't it time for an upgrade? Try ebay for good used equipment deals.

I have a pair of JM lab Electra 905 speakers, running through a DNM amp and power amps. When powered up, the left speaker makes a very loud humming noise. This has happened recently. I haven't changed...


Hello
Switch on your amp, keep its volue down to extreme low, and listen if there is still hum through the left channel or not. If still there is hum, the left side power amplifier section inside the amp;ifier is faulty. If htere is no hum at this state, hum enters thorugh the audio input terminal, and the input wires must be checked for open sheild connection. OK.

When you turn player on: Screen said "Hello" , then "Protection"


Sounds simple... usually "protection" means that a speaker or a speaker wire is shorted out. Or that the volume is just too damned high... how loud is the receiver's volume setting? If the bass tone control is jacked and the loudness button is on, even with no shorted wires, the amp can go into protection from an internal overdrive. Might be that you just need to do like your mom says and turn it down!
If you have an ohmmeter, speaker or wiring problems are easy to test, if you don't, you can still do it all mechanically... here's how
Turn off the receiver and start by disconnecting your speaker wires at the back of the receiver. With all of the speaker wires removed, does the thing still go into protection when you turn it back on?
If not, good. If it does, find a service center.
Re-connect the speakers to the appropriate terminals one speaker at a time, turning off the receiver each time you make a connection. After connecting one speaker, turn the receiver on and see if it shuts down. If not, then turn it off and add one more speaker.
Do this until you find the culprit. Leave that suspected bad speaker's wires disconnected from the receiver and test all the rest, connecting all but the bad wires.
Now, disconnect the speaker from the other end of the bad wires and spread the bare wires apart so they don't short out. Connect the wires ONLY at the amplifier end and turn the amp back on. Protection?
If yes, the wire is shorted out somewhere. got cats?? If everything is OK, turn off the receiver and reconnect the speaker and test again. Make sure the wires aren't shorted at the back of the speaker. You really need to check all the speakers to make sure their connections are "clean" and make sure that there are no stray wire strands anywhere or that the wires aren't stripped too much so they might be able to short out. After the wires are connected to either a speaker or an amplifier, you shouldn't be able top see much of any bare wire, but you already know that, right?
Some folks strip way too much off the wire and the wires simply touch the wrong things and ... badness happens.
If all the connections are clean and the receiver still shuts down when this speaker is connected and the receiver is turned on, swap a working speaker onto these wires, leaving the suspect speaker disconnected and making sure the other bare wires won't touch anything or each other.
Back on with the working speaker... good? If so, then we're determining that the problem is probably in that one speaker. If not, then we have a deeper problem.
Reconnect the suspect speaker to the other wires and try again. Good? Then you have "fixed" the problem by cleaning up the wiring connections. If it shuts down again, then you need to fix or replace the bad speaker.
If everything works now with the volume down and such, then just use a little self control. If it's still messed up, you may need a trip to the service shop
Good Luck

Very loud odd noise coming from radio speaker


There might be 2 probs
  1. The wires soldered to the the CD/FM input/output wires might have come loose leading to short/sparks causing the loud sound(constant).
  2. If there are any sockets requiring plug-in they may require cleaning with pure alcohol or rectified spirit(unlikely).
  3. The wire leads going to the speakers may be partially loose........................sodeep

Marathon 2000 amp... PROT light


Ok this means the AMP is in protection mode!..most likely the cause is a short in your wireing from the speaker wires! check all wires going in and out of amp! Look for stray wires touching metal or other contacts! (If this does not fix it the short may be inside of amp!
(This has nothing to do with a fuse!)
Please rate this FREE response!
THANK YOU!

Solid state transistor amplifier. The speaker 'thumps' loud when switch on.


check proper connection to output stage(good condition of speakers cables)no short in cables or touching each other.-no problem in speaker itself(speaker coil short circuit or open circuit)-disconnect all from amp and check if it is ok-you will have a problem in cables or speaker if not you will have a problem in your amp.
