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 a8000t amp with the protection light on, is the amp broke?


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.... 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 :)

Where can I find a cooling fan for a Audiobahn a8000t amp?


Hello fornda,

The fan looks very similar to a 3" muffin fan. The fans from most computer cases would probably fit. You may have to modify how it mounts, and perhaps the connector, but the voltage is the same.

Here's an online retailer. I'd look for the highest CFM at the lowest fan speed to keep the noise down.

Hope this helps.

Audiobahn A8000T has power but is not hitting


Check your cap, it prob went bad. That could be restricting the power flow now. Try it with out the cap. that just might be the prob.

Audiobahn a8000t problem


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

Amp has power, but nothing going to subs


did you check on the 'remote' terminal? It should have a +12 vdc to let the amp work. You can check this with a voltmeter. Or might be in 'protection mode' (speaker cut-off relay).
hope this helps

Amp protection light comes on when raising volume...


It sounds like you either have too low of an ohm load or the voltage is dropping at the amplifier's power terminal.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp 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 is below ~11 volts, you need to check the wiring feeding whichever line is too low.


If the voltage remains near or above 12v, disconnect one speaker and see if it shuts down. If it doesn't, disconnect that speaker and connect the other speaker. If it only shuts down with both speakers connected and the voltage is staying above 12v, the ohm load is probably too low and you'll need to rewire the speakers.

Amp cuts out and back on 30 or so seconds!! Volume has no impact


You need to check the B+ and remote voltage on the amp when it cuts off (assuming that you can recreate the fault).

With your multimeter set to DC volts and the black meter lead on the ground terminal of the amp, touch the red lead alternately to the B+ and remote terminals as the amp shuts down. If the voltage drops below ~11 volts, you need to check the wiring feeding whichever line is dropping too low.

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
