Blowing fuses under hood but nothing looks smoked in the amp

I am blowing 80 amp fuses when the amp turns on. I have disconnected subs, RCA's, and just have 4 gauge for power, 2 (or dual) 8 gauge for ground, and a remote turn on connected. If I disconnect the remote turn on and connect power and ground, it doesn't blow the fuse. Its not until it recieves a signal from the remote turn on. I have everything turned down on the amp, and like the subject says, nothing looks smoked in the amp.

You need a bigger fuse holder. Your amp is tryin to take more than 80 amps. Mine did the same thing and in theory it needs 180 amps at full power. Upgrade the fuse block and it will stop

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

Pdx1-1000 keeps blowing fuses

It sounds like you have either shorted output transistors or switching transistors. You would need a multimeter and knowledge of transistors to be able to check them.

THE AMP TURNS ON BUT THE FUSE UNDER THE HOOD KEEPS BLOWING and the sub wont turn on but the amp turns 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 have warranty . Please use volt meter to test correct voltage and ohm feas ng on speakers. .A thumbs up would be greatly appreciated if this answer is helpful to you. amp-turns-but-zb4bomd1rt4qms0dqd12kkt2-3-0.jpg

Well, sounds like you have an internal damage since it smokes, if it smokes as soon as it kicks on, and blowing the fuse right away, I would have it fixed. But my guess would be something with the ground that is making this happen, or some how your power is grounding on the amp. When ever smoke comes into play, thats never good any way at this point you gotta admitt that thiers internal damage.. blowing fuses can also be cause by over working your amp. along with the sub load at 1 ohm make sure your amp can do the same.. hope this was helpful in some way

I have a dual XIA3145 580 watt amp that keeps blowing fuses

Generally, this indicates that there's at least one shorted output transistor.

Disconnect all speaker wires from the 'amplifier's speaker terminals' and disconnect RCA/signal cables from the amp. If it powers up normally, the speakers/wiring need to be checked. If it still blows the fuses, the amp almost certainly has shorted output transistors and will need to be repaired.

I'd recommend using two 10 amp fuses. The amp will power up with 10 amp fuses if there is no problem. If there is a problem, there's less of a chance of doing more damage by using the 10 amp fuses.

Let me know if you have any other questions.

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)

Amp not working

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

You should confirm that nothing external is causing this by disconnecting the speaker wires from the amplifier's speaker terminals and disconnecting the RCA cables from the jacks.

What make/model amp is this?

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.

Amp blowing fuses

The amplifier probably has shorted output transistors.

Disconnect the speakers and RCA cables. Replace the fuses with two 10 amp fuses or a single 20 amp fuse. If the amp blows the fuse when it powers up, the outputs are almost certainly the problem. Don't try it with the two 30 amp fuses. The smaller fuses will provide more protection for the power supply. If the amp powers up with the smaller fuses and they don't blow, check the speakers and the wiring (for shorts to ground or shorts between wires).

Amp in protection mode

Disconnect all speaker wires and signal cables from the amp. If it powers up normally (doesn't go into protection), the wiring needs to be checked. If it still shuts down, the amp likely has blown output transistors.
