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?

PA Amplifier blows fuses


The fuse is blowing due to an overload. It's often and very likely caused by a transistor or ic that has gone short. The main culprits are the power transistors of the amp or whatever is on the big heat sink. Transistors will show the fault when you connect an ohmmeter to the terminals. It will be just like you have touched the test prods together! I don't think in your case it will be in the power supply. It's often caused by speaker cables that touch together.

I have a 97 galant that keeps blowing the 100 amp fuse? alternator tested good twice checked wiring reads good is there another fuse ?


Usually that fuse powers the alternator and the fuse box.
It would have to be a big short to ground to blow that fuse.
Its possible the main wire to the alternator is touching a metal spot, or the alternator is shorting out inside when it is running.
What is draining the battery may be something else, or the battery could be discharging after the fuse blows if the alternator is not charging it.

I have "cooked" (i think)


When the fuses blow like that suspect an overload in either the power supply or main amp stages. I think you might have damaged one or more of the output devices. They can develop faults quick if you're using the wrong type speakers or have faulty wiring to them. The main cause of fuse blowing is a semi-conductor device that is acting like it is a piece of wire. For instance an output transistor when connected to a multi-meter on the ohm scale, will show a full scale deflection, just like if you had touch the two test probes together.

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)

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.

Have a kenwood kac849 600w amp keep blowing fuse on amp as soon as power is too it power wire got wet and now this can i bypass that fuse some how


It would be very dangerous to bypass a fuse. If it keeps blowing, bypassing the fuse will only create lots of internal damage and maybe a fire as well. The fuse is blowing for a reason, the amplifier is not going to somehow start working because you bypassed the fuse. You also need to stop trying to turn it on, every time it blows the fuse, it keeps stressing the components inside. You have a shorted power supply, probably water damage as well since the power wire got wet.

I repair car amplifiers for a living, and can tell you with all honesty that bypassing the fuse would be a terrible mistake to make, the amplifier would end up being un-fixable with holes burned right into the board.

Please, just take it in for service or get a new amplifier. That is the only sensible thing to do. The amp will not start working bypassing the fuse, it will only start smoking.

Since it's an intermittant problem and a relatively expensive amplifier, you should have it checked by a qualified tech. If you keep trying to power it up, it will eventually blow out the power supply transistors which will add as much as $100 to the repair bill.

Fuse keeps blowing when sub volume is turned up


the amp draw rating on the amp is 100 you need to put a larger fuse in, such as a 150 amp, it would be a good idea to go to 0 ga but not needed. you might also want to upgrade your altenator.
