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.

My 1800w kenwood amp keeps blowing the fuses


there are 3 reasons your amp is blowing fuses. The first is that it is no good. If amp plays at all then that is not the case.

Then it is more likely 1 of or both of these 2 reasons.

  1. The fuse is too small for the load you are putting on it and needs a bigger one.
  2. You have the amp wired to an ohm load that is too low.
Try upping the fuse to the next size up.

If the amp just blows the fuse and will not work at all. It may be shot.

Kicker IX704 amp fuse blowing problem


Hiya, sorry to say it could be anything from the flyback diode at beginning to output devices at end of circuit and guessing would lead to a whole lotta frustration. you going to have to find someone who at least has some experience to test with a meter etc to locate the fault (but it is more likely to be one those, (protection diode or outputs). Anyone in the area with electronic experience should/may be able to assist there.

Amp keeps blowin the two 30amp fuses on the amp.


Make sure that the speaker wires are wired correct at both the amp and the speakers......otherwise it sounds like the typical death of a power acoustik amp (great amps, but prone to a premature death)

Blowing of fuses


The reason your blowing fuses is the amp needs at the least a 150 amp fuse on the wire that runs to your bat. There are fuse blocks that you can put 4 40amp fuse and theres the high dollor ones that you can put all the way to 200amp. When you trun up your amp its drawing to much current for the little 40 amp fuse that you have and will blow it everytime. I recomend Running a 4 gage wire to bat and ground with same. Get you a 150 or above amp fuse from a car audio shop somewhere. anyway sounds like from what you decribed, theres nothing wrong with your amp just the wires and fuse are not big enouf to handle the current that your amp pulls.

BLOWS FUSES


If it blows fuses only after the remote voltage is applied, the amplifier likely has shorted output transistors.


Let me know if you have any other questions.

Keep Blowing Fuses


Sounds like the amp is shorting somehow. You are obviously shorting out somewhere between the battery and the amp. Are you sure you grounding location is a good one? is the fuse blowing only when you turn the stereo on? Something is not hooked up correctly.

If the fuse at the battery is blowing then it's a short.

If the fuse on the amp is blowing then its probably a bad amp.

Disconnect all speaker wires and RCA cables from the amp. Replace the fuse with a 30 amp fuse and power up the amp. If the fuse blows, the amplifier probably has shorted/leaking output transistors.

40amp fuse blows


Measure the DC voltage across the B+ and ground terminals as well as across remote and ground. If you have less than 11 volts when the amp tries to power up, the amp could be shutting down due to low voltage.

If the voltage remains near or above 12v, disconnect all speaker wires and signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down or blows the fuse when you apply remote voltage (turn the head unit on), the amp likely has blown output transistors.
