Re: RCA rt2500 "CHK SPKR" comes on when i turn it on.
"CHK SPKR" Check Speakers. Remove all speaker wires and turn on receiver. If it still says check speakers, you have an amp that needs output transistors or possibly just soldering of an emitter resistor but thats rare.

You probably have a blown channel. but check for a shorted speaker wire or bad speaker. Remove all speaker wires from the rear of the receiver if it still says check speakers when turned on, then one of the output channels is bad.
It's telling you it thinks tghere's a short on the speaker outputs. With NO speakers, that is bad.
Generally speaking, an amp protects itself from heat, shorts and overloads.
Overloads can be from excessive periods of high output and shorts would be wiring issues or a speaker blowing up.
You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.
If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced hands-on tech.
Hello, here is Clarions wire codes. FRONT Right SPKR: +Gray -Gray/Blk, FRONT Left SPKR: +White -White/Blk, REAR Right SPKR: +Purple -Purple/Blk, REAR Left SPKR: +Green -Green/Blk
Brown Wire = Phone Mute Lead (If applicable) Yellow Wire = 12V battery lead in (Connect directly to battery) Red Wire = 12V Ignition wire (Connect to Acc switch) Blue/White Wire = Amp turn on lead Black Wire = Chassis Ground Orange/White Wire = Illumination Lead (Connect to dimmer switch) Blue Wire = Auto Antenna Lead (lowers power antenna Do not use for Amp Turn on! Use the Blue/White Wire for Amp,EQ, Ect.. turn on wire only
RCA Connectors if applicable:
Black RCA Harness: White RCA = Rear Audio Left Sub Output 1 Red RCA = Rear Audio Right Sub Output 2
Gray RCA Harness: White RCA = Front Left Audio Out to amp Red RCA = Front Right Audio Out to amp
That message means that you have a bad speaker or you have a bad amplifier IC most of the time. The amp circuit could have some other problem, but more times than not it is the amp IC.
How to check if it is the speakers or the amp circuit:
Unplug the speakers and turn it on. if you do not get the error message you have a bad speaker. If you do get the error message you have an internal amp problem. Then start plugging in speakers one at a time. If the unit turns on and stays on for a few minutes, turn it off and then plug in one more speaker. Keep doing this unit the unit gets the error message and when it gets that message you know that the last speaker you plugged in is the bad one.
Now the bad news
RCA no longer sells parts for their audio equipment. When the supply they have on hand right now is gone, thats it, no more RCA parts.
Now the good news.
The amp IC they use is a generic type that you may be able to get from another source.
But that is only good news if the amp IC is bad. It is the likely suspect, but without troubleshooting it on a test bench with the proper equipment, that can only be a good guess.
If you have found this help to you a good rating would be really appreciated.
Your problem is the output IC's The case where you say the speakers buzz tells you theres a short in the audio outputs. If your unit didnt shut off, the speakers would fry and the unit would also smoke. These are solid state devices and are soldered in, and are not concidered user serviceable parts, unless you know how to solder and trouble shoot Stereo systems. This is a job for the pro if you want it fixed. Good Luck
If you have speaker wires that have strands, you may be getting a short if one small strand is shorting across the terminals, or a poor connection. Check carefully, perhaps even by disconnecting and reconnecting the wires.
Also check for proper polarity - positive to positive, negative to negative. (unlikely since it just started).
You can also get a new set of wires and check speakers one at a time to see if it goes away. or get another speaker that works and then replace each one with that speaker in turn to see if it resolves it.
