Are you sure you don't have the positive and negative power wires reversed?

Does the fuse blow without remote voltage applied?

Fuse apx200m


HI,
If the fuse is blowing of then there is problem with the inverter stage of amplifier. There is an inverter stage in the amplifier to boost the 12V to + or - 30 to 40V normally. Its a switching circuit normally uses Mosfets and ferrite core transformer and a driving IC. If the mosfet is shot then the fuse will blow off immediately after power is connected.

Check on thing remove the REM connection and then connect the power. If the fuse blows the there is fault with the Mosfet Its short.
If the fuse blows only when you connect the REM then the amplifier stage is faulty.

Also check by disconnecting the speakers. if any of the speaker is faulty then there is a chance for fuse blow off.

your inline fuse wouldn't blow if there was just something wrong with the amp. the amp fuse would blow if that was the case. something is faulty with your wiring. you probably have the wires touching somewhere or are in the wrong terminals at the amp or on the wrong battery terminal. or your power wire is grounding out somewhere. its not the amp. its your wiring

What do you do when your amp keeps blowing fuses


First off which fuse is it? The inline fuse from the battery or the amplifiers power supply fuse? Blowing the main fuse from the battery is caused by either the load (your amp) drawing too much current or you have a short to ground somewhere. Maybe there is a tear in the 12Vdc line and it is shorting to the chassis of your car. If the amps power supply fuse is blowing as soon as it turns on your amp has a shorted power supply. This will require internal component changes by a technician. If it is blowing after operation at high volumes I would say change the impedance that the amp is driving. If you are at 2 ohm try to rewire your speakers for four ohm. (go from parallel to series wiring then bridge mono or operate the amp in stereo mode)

Power fuse on amplifier blows as soon as the power cable is connected


you should check the fuses your using may be too small and make sure you connect the positive first then the ground cable and there are no shorts when you ground the amp.

the most common will be the fuse ampage is too low thats why its blowing when you power the amp

I have a 25 wat fuse in my power wire connected to my amp and i keep blowing it. should i put a bigger fuse in it?


Hello grabert205,

You do not say if the fuse blows immediately upon powering up or while the amplifier is operating. If it blows immediately, I'd check the power and ground.

If it is blowing the fuse while operating, I'd try a 30A and see if it holds. At maximum output of 100 watts times 4, the amplifier needs about 31 amps of current at 12.8V. So driving it hard could certainly blow a 25A fuse.

Hope this helps.

Help my fuse is blow!


If the amp blows fuses only AFTER you send remote turn-on voltage to the amp, the amp probably has blown output transistors. To eliminate other possible causes, read through the following page.

Amp keep blowing the 20amp fuse


There seems to be a short circuit inside your amplifier. It could be one of the amplifier mosfer/transistors or a diode that is connected nearby the power input.

AMp keeps blowing fuses


When any amp blows fuses, this indicates that something is drawing too much current. The most common cause are components in the output stage and driver stages that have become defective.

On the amp that is blowing the fuse with the volume being turned up, this means that the output stage is partially working. The short or over-draw of current must be in the output stage, or what is loading it. It is possible in this case that a crossover in a speaker unit is defective, and is drawing too much current. I have seen this with especially sub-woofer crossovers, and the driver itself. Subs pull a lot of current because of the amount of drive power required to have very strong bass sounds. Other than that, this still does not rule out the possibility of the problem being defective components in the amplifier.

Blowing fuses under hood but nothing looks smoked in the amp


Sounds like the amp is fried, most likley in one or both of the output sections. Good luck.
