Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Definitely worth repairi .A thumbs up would be greatly appreciated if this answer is helpful to you.

Disconnect the speaker wires then the power and ground completly. Then power up the amp and if the protection light turn on the you have an interanl problem if not then you ohm is problably to low and causing the amp to go into protections.

My A8000t amps red protection light is on checked


When ever the amp stays in RED protection mode with out any speakers hooked up to it, YOUR amp has internal damage some where. Can't tell you how much to fix, Could be cheap or not worth it. Talk to your local electronic repair, would be a good start.

Amp not working


I had a similar problem with a pyle amp. try to disconnect the speakers and turn it on if the protect light doesn't come on then you might have blown something in your amp and it needs to be repaired. For my situation it was a blown resistors and only 1 channel worked. If you don't have soldering experience then I wouldn't bother trying to fix yourself, an unsteady hand can ruin your repair.

AMP.... question


12vDC
CFM is negotiable - as the higher RPMs the more air it moves. (also louder).
Audiobahn is out of business - and unless someone is willing to tear theirs apart for your info - get whatever they have in stock :)

Amp keeps cutting off


Do you have heavy enough gauge wire supplying B+ to amp.Big amps draw a lot of current and require very heavy gauge wire. The longer the run the heavier the gauge needed.

I have an audiobahn A8000t amp with the protection light on


There are many different ways that an amp can fail but the two most common failures are shorted output transistors and blown power supply transistors (< those are not blown). There are several types of protection circuits in amplifiers. The most common are over-current and thermal. The over-current protection is supposed to protect the output transistors. Sometimes it doesn't work well enough to prevent the failure of the output transistors but it will work well enough to shut the supply down before the power supply FETs are destroyed. If the amp remains in protect mode, goes into protect mode or blows the fuse as soon as the remote voltage is applied, shorted output transistors are almost certainly the cause. If the fuse protecting the amp is too large, if the protection circuit doesn't respond quickly enough or if the power supply is poorly designed, the power supply transistors may fail. If you see a lot of black soot on the power supply transistors (near the power transformer), the power supply transistors have failed. Soot on the board doesn't necessarily mean the transistors have failed. Sometimes, technicians don't clean up the mess from a previous failure.
In general, when a transistor fails, it will either short (common for output AND power supply transistors) or open (common for power supply transistors). Transistors act like valves. They control the current flowing through a circuit. A shorted transistor acts like a valve that's stuck open (passing too much current). In the case of an output transistor, the shorted transistors tries to deliver the full rail voltage to the speaker output terminal. If you've ever seen a damaged amp that pushed or pulled the speaker cone to its limits when the amp powered up (common on some Rockford amplifiers), that was almost certainly due to a shorted output transistor. When checking transistors, you most commonly look for shorted connections inside the transistor. You do this by using a multimeter to look for low resistance connections between the transistor's terminals.
Note:
I used the terms short and open on the previous paragraph. A short (short circuit) is a path through which current flows that should not be there. An open (open circuit) is a break in the circuit.

Audiobahn a8000t problem


If the protect LED is lit, the amp probably has shortedoutput transistors. To eliminate other possible causes, read throughthe following page:

Let me know if you have any other questions.

Protection Light On


Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you didn't fry speakers as well. Please check speakers impedance. A thumbs up would be greatly appreciated if this answer is helpful to you

Protection mode


Driver ICs or transistors,op-amps that create the idle bias circuit,the protection circuit, the power supply. You should have a schematic of this unit and know how to check the solid state devices for shorts. GOOD lUCK

Solution


Sounds like you have shorted output transistors or IC'S There is one test is to disconnect all the speakers and see if they still blow. If they do then you need to have the amp fixed or replaced. If they dont blow try connecting up each speaker till the unit blows the fuse asjust maybe you blew out a crossover or a speaker or two?? If you have an active type crossover then I would check that device as well. Good Luck
