A Power overload occurs at minimal volume

When Stereo is turned on, the amp is recieving power, but the speaker overload light comes on almost immediately, I've checked the speaker wiring from amp to sub and its fine. I've also tried swapping out the amp, and got the same result.

300W Pyramid PA305 protection light


What is the speaker load in Ohms that you are running? Or what exactly is hooked up to it? are you bridging it? The protection light will come on if the load is too much for the amp to handel. If the load (in Ohms) is less than the rated load that it can run, it will stop the output to keep the amp from self destructing. The amp will sense that the demand for power will be too high for the amps circuitry which will either make the amp get so hot that it will burn up the copper on the board or more likely burn up the power mosfetts that power the speakers. If the Ohms are within range then it will allow power to flow through the circuit until the rails that the mosfetts are bound to until they get so hot that it will go into thermal protection. So if your amp has both thermal and overload protection lights and the overload is light then the load is probably too much for the amp. if it's bridged in mono the you can only have 1 speaker setup hooked up it if it's a 2 channel amp. a 4 channel amp bridged in mono for both front and rear channels will be able to have 2 speakers rated a 4 ohms each hooked up to the amp 1 set per bridged output or channel.
Try it running in stereo with only 1 speaker per channel and see if it will produce sound. If not then you have an amp that has internal problems and will need to be serviced. Check your warranty to see if you are covered.

Why the red light comes on when i turn the volume up


Hello
It is an overload indication. Check the wiring of the speakers. If speakers of very low impedence have connected to this amp, they will overload the amp, and its protection circuit will work. Anyway, the output impedence of the amp is now very low than specified. OK.

Evet time i hook my 1200 watt power acoustik and turn it up it cuts off


Usally When something like this occurs its because the amp cant handle the reciever. Meaning the reciever is pushing out more than what the amp can handle. As a safty feature to save you from blowing your amp or speakers the amp will shut it self down to minimum as you described. This also occurs when the amp over heats or doesnt have enough ventalation and once again as a safty feature to save your amp it shuts down. My first suggestion is to turn the "Loud ON" mode off on your reciever. As this feature can blow your speakers and can also cause this problem. Also do not use any factory settings on your reciever. It is almost always the bass in any given system that causes this so turn the bass down some on your reciever or on your amp turn it down and then adjust up and down from the reciever. Im sure you probably like the bump bump bump, I do to but your going to have to eiather buy an amp that can handle what your reciever is pushing, or turn it down a bit. You should also check the fuses for not only your amp but for the system under the hood near the battery. My own personal experience I have blown fuses when the system shuts down. Hope this helps

My Alpine MRP-M650 Amp is acting up. When I start the car, if the volume is at low, the subs don't work. But when I turn up the volume, they eventually kick in, then I can lower the volume. But when...


There are a lot of things that could cause this issue ...
1. Your amp requires more power than it gets when you start your car, and needs to charge up before it can work. If this is the case, you should be able to give your stereo about 5 minutes to warm up at low volume and it should come on. This happens a lot with amps with built-in capacitors (capacitors give you stunning, instant kick when working, but require a bunch of power to initialize). If you wire a bypass switch for the power to your amp and bass components, you can turn it on separate from the rest of the car and allow it to charge before you start your car (just be careful to turn it off when you are going to be away from your car for a while since this will allow your system to drain your battery).
2. Your amp might be set incorrectly for handling the system you are running. If your Ohms do not match up exactly (8 ohm speakers with a 4 ohm amp -- it's the "Impedance rating") then the system should not work at all, or should burn out the amp ... but with a jury-rigged system it can work. If this is the case, I recommend getting a new amp that matches your speakers.
3. Depending on the amp, there might be a volume-based cutoff that is working improperly. Turn on the car with the stereo at low volume. While the speakers are still not working, check to make sure that the amp has power, and seems to be functioning correctly. If everything seems like it's on the up and up, but the speakers are not working, try changing the volume-filter options on your amp.
4. I put this last because it seems like you know what you are doing with the system setup, but it is possible that you have a bad connection between the speakers and the amp, or between the stereo and the amp. There could be a loose connection somewhere (either inside the amp, between the amp and the speakers at the jack, or between the stereo and the amp at the jack). If this were the case, everything would look perfect from a visual inspection, but there could be a tiny space, or corrosion in a connection. Turning the stereo up to a high volume could then bridge this short circuit, and the electric force could magnetize the connection shut, allowing you to then turn the stereo down with the working connection. The best-case scenario here would be an external wiring issue, where you can clean any corrosion off the connections with an eraser, and reconnect everything tightly fixing the problem. The worst case would be a short WITHIN the amp, which would have to be repaired by someone with a lot of time and a circuit tester -- in which case you might be better off trading the amp in for a new one.

Red Power Protector light


Hi, the only way i can see the amp resets the stereo is that power is dropping. The amp should have its own wires directly to power/battery so as to not affect anything else.

On the protect, try to disconnet all the speakers, make sure the power is OK. If it appears to work, the there could be a problem with speakers/cables. Try a different speaker to see if it works. If the problem continues with speakers off, a different speaker etc, then there is a problem with the amp. Hope that helps

Interior speakers cut out when the volume is turned up


You may have speakers of an incorrect impedance attached to the unit since the problem occurs when audio signal level is increased and the current goes up.The unit is shutting down to prevent damage. I would check the speaker connections and make sure that the speakers impedance are matched for the unit you are using.

No sound coming out


I often troubleshoot these issues via a stereo head set, modify the leads so you can "Touch" them onto the Speakers Output Terminals, connect the "Shields" together, thats "Earth" and the other Two, are Left & Right... with the Amp's volume turned to about 25% volume, connect up the Earth wires to the Chassis with a clip, under a srew etc, just make good contact... then touch the Left & right wires onto the output, ya should hear sound... if not most probably the Output device(s) may have gone faulty.
