Earthquake mobile amplifier- fan overruns

When i hooked up my bass knob the amp made my subs hum i unhook the rca but still humming unhook bass knob still hummin

Your power supply is toast. Might be repairable at a electronics repair shop. But for an Earthquake amp I wouldnt waste the money.

the amp dose not have any such internal batery it is probly tosted call me 256-698-9903

if your amp keeps shutting off, it means that you r overworking it, and it's getting hot without minimal time to cool off. my solution is, and i've done this. i bought four mini fans and wired them to the heat vents, two of them to the vents on one side to **** in cool air, and the other two on the opposite to **** out the hot air. this does work, and keeps your amp cool, or buy an amp that comes equipped with a built in fan, you may pay alittle more, as they say you get what you pay for. hopes this works for you

If the amp is off completley it sounds like the fan is running of the incoming 12Vdc line that is constant, not switched. That would be an issue with the amp manufacturer. There is a comparator circuit that uses a Thermistor that is RTVd to the power transistors heatsink block. When that voltage reaches it's reference voltage the fan will kick on. The amp manufacturer is switching the fan supply in with a relay to the 12Vdc line (more current capability) and the relay contact is stuck closed even when you turn the amp off. Does the fan run indefinitley or does it shut off over time?

I would go with a 40 or 60 amp fuse, this should be ok, you will hardly every run the amp to full capacity so its better to be safe than sorry.

I want skimatic earthquake D mono amp

Cables are either shorted, or deck is putting out too much power for input on amp... many new head-units will put out up to 7v on the output jacks (RCA) the amp may only want to see up to 1v will need to consult head-unit manual for adjustment of outputs.

yes , it is normal for the fan on the amp to turn on when the internal tempature reaches 110 degrees the amplifier is not an intellegent device, all it knows is the temp threshold has been reached and its themostat will close the relay and try to exhaust the heat from the amplifier....I have this same amp, and I live in florida...thank goodness it is a very minimal draw,,,btw if it was a 100 outside it was well above 100 inside your car and even hotter inside the amp ,,the heatsink will conduct heat inside the unit when the unit is off....so the unit is behaving normally...Congratulations for buying a high quality piece of electronics
