Question about Pyle PLA2580 Car Audio Amplifier

Open Question

Amp Turns on then turns off

Same as other guy 5 seconds later the light goes out on my remote bass boost....the logo on my pyle 2580 amp still glows red but my blue bass lights go out with my subs, but the red light remains on....when i fool around with the remote wire and touch it to a ground in my cd deck it turns on for the same 5 seconds then turns will not stay on when i place it together with the little ground wire in my deck. i re-taped my 4 gauge ground wire in my trunk back to the bare metal to see if it was a ground problem, same stuff.....i bought a new remote wire, same problem...the only thing i didnt check is my power cable. but why would it be the power calbe concidering even when the sound dies in that 5 seconds the red light remains on....confusing

SOURCE: Protect light will never go off

Unfortunately, it sounds very likely that you have a defective amplifier. Usually you see a protect light on an amplifier because of an internal short, supply voltage too high, voltage too low, or speaker connections of too low impedance or grounded. If your speaker wires are completely disconnected, that eliminates the most common external cause of a protect light. Also, a protect light from the voltage being too high is very unlikely without the engine running (and an alternator problem). The "other positive cable" you're referring to is the remote input, and it won't cause a protect light no matter how it's connected. You'd need a voltmeter to do much more troubleshooting; a protect light can be caused by a very poor ground connection, or it's possible that a poor connection at the battery or fuseholder, or a defective fuse, is causing a severe voltage drop. However, based on what you've described, it seems most likely to me that your amp is defective.

SOURCE: Trouble connecting marine amp to stereo

Hello lizskates814,

You can use either the high level (speaker) or the low-level (RCA's) inputs to the amp, but not both. Choose whichever one sounds the best or is more convenient to install and leave the other disconnected.

Hope this helps.

SOURCE: Live RCA cables????!!!!???

Ckech the ground, the only thing i can think is that the amp is trying to use them as a ground... but you probably have an extremely fried amp and guts are melted and making your RCAs make contact with the power wire, so i'd be real careful, and probably trash the amp. sorry about your luck dude...

Mtx tna251 amp has bass remote that has a light glowing but turn knob up and down and no difference like simply not working no difference in bass? Posible causes,

It is actually in the controller, if you turn the remote all the way down and press on the controller until the bass goes off, you will be able to turn the bass up and down with the remote, mine worked but stopped after a month, I tried adjusting the amp but then I noticed that if I wiggled the knob on the remote that it would work, I mashed mine until it worked again and velcroed it to my console sonibcan get it on and off easily.

KAC9103d been running great for a year, factory refurb. for a month been losing sub output. checked all connections again, everything good. Turned on went driving 15 minutes later lost bass ckd again red...

Could be that you have a partially roasted(blown) coil on one of your subs which will function- but will keep tripping your amp.You can check that out just by using a different set of subs to listen to and by the process of elimination if the problem goes away then you know where the problem is at.Also check your gains you might be riding the gain a little high which causes distortion which causes heat(FAST) which will cause the amp to shut down completely or some amps will decrease output in a programmed attempt to save itself.turn the bass boost down to half if you even use it at all- that too can cause massive distortion in the amp itself,meaning only that if you have the bass boost on your deck turned up and then you turn the boost up on your amp the sound signal is then WAYYY distorted which will cause a thermal shutdown too. Last thing is to make sure that your subs arent running below 2 ohms because i believe that particular amp is designed to put out about 900 watts at 2 ohms.good luck

The protection modes in these units ****. Most new units have them. What I do is turn down settings on deck and turn up amp as much as possible. Then the protection won't turn on because you won't have to turn it up as high.

Amp turns off

Sounds like remote turn on wire is bad. If using aftermarket HU, find another location to power amp. Try the the power antenna wire on the HU to run the REM.

Power light on the amp goes on after 5 sec off ultra linear 1200

If you run the remote from the battery you will need a on/off switch. Sounds like the amp is overheating. Also, I don't understand bridge the remote and power. They should be seperate going into the amp.

Since you haven't received a response, I'll try to help you through the troubleshooting. The amp probably has shorted output transistors but before you start checking components, you need to 'confirm' that you have no bad connections in the power line.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage goes below ~11 volts when the amp shuts off, you need to check the wiring feeding whichever line is too low.

If the voltage remains near or above 12v, disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up normally, the wiring needs to be checked. If it still shuts down, the amp likely has blown output transistors.

Let me know what you find.

The Amp stays on because you have a constant 12V to the Remote.
If your stereo remote is no longer working then run a wire from a 12 volt source that turns on and off with your ignition something like your radio fuse in the vehicle fuse box.
As far as the Bass Knob if it is connected properly and still not working check the line for wire kinks or cuts that may have happened during installation if you cant find any problems you can get a universal bass knob that plugs via your RCA cables for under 20 bucks.
Hope this gives u some ideas.
