The amplifier probably has shorted output transistors. If the amp only blows the fuse after remote voltage is applied, the damage may be minor. They generally blow two transistors. Sometimes that's all that needs to be replaced.

Let me know if you have any other questions.

Amp is blowing inline fuse everytime i connect the pos.&neg. wires


Hi thetexster74,
Blowing of fuse indicated of shorted parts inline with the supply voltage. Most common shorted parts is the sound output IC which is mounted in the heatsink. If your handy with electronics, have knowledge in soldering and desoldering technique, pull-out this IC to the board and then try the unit. If the fuse does not blow this time, you must replace this IC and your unit will back to normal again.
Let me know if the symptoms still persist after you've done the above solution.
Hope I helped you.
Thanks for using Fixya.

I just replaced an amp and now the inline fuse by the battery keeps blowing


Most likely you have your power and ground connections reversed on the amp. That will cause the fuse to blow immediately upon contacting the two sides of the fuse. If the fuse stays intact for a short while but pops after turning the amp/car on and your connections are correct then there's a problem with the amplifier and it either needs to be serviced or replaced.

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)

Hi. I have a Kicker amp KX1200.1 that doesn't seem to be working. I think it blew a fuse. Do you know how I can get that fixed?


You should have an inline fuse (external) at the amp and one at the battery. There are not fuses on the amp.

Keep blowing fuse under hood when i put power wire in to amp


disconnect the negative battery terminal, replace the fuse with all the wires hooked up to the amp and reconnect the battery terminal, that way the initial surge of power goes through the negative terminal and not your inline fuse. That should solve your problem.

You probably need to run 4 gauge wire if not already done so, and check the fuses on the amp, add the fuses together then buy the right fuse rating for the fuse connected under the hood

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.

Amp blows fuses "immediately"... HELP


for this to cause a problem with amplifiers there is something internally wrong with it. Most of the time the mosfets take a shit from the hot...cold....hot....cold atmosphere its put in by all of us audio people. If it still has warrenty that would be the easiest route to go. Send it in to them and have them fix it for FREE lol!! well sorta. Hope this helps you understand why you are blowing fuses.
