Klh subwoofer keeps blowing it's fuse.


Most likely the amp in the sub has blown. It will need repair or replacement. I'd take it to an expert in repairing amps, it's not a job for you unless you're experienced in troubleshooting these things.

KLH ASW8 Powered subwoofer keeps blowing 3A-250V fuses


The transistors at the output stage of the sub amplifier circuit might be shorted so each time you power on, the circuit draws a very high amount of current which causes the fuse to blow. It's definitely a problem with the circuit so using a higher current rated fuse would probably just result in damaging the amp even more. You should ask a qualified electronics technician to take a look at it. I hope you can fix it.

Polk Audio PSW202 subwoofer. Replaced burnt fuse but blows the next fuse after connecting to amplifier and powering on. What else can I do?


Fuse probably went bad because either the large filer capacitors at the edge of the PCB went bad and or the final output IC mounted on the heatsink(15 pin) fried. Check the capacitors and all the semiconductor components on the board for burn marks or corrosion. You have to remove the heat sink clamp from in front of the output IC to adequately visualize its condition. In fact you might have to remove the large aluminum heatsink attached to the chassis to get a good view of the IC. If it or the heat sink clamp show signs of thermal burns you need to replace it. The IC is a TS TDA7294 mono audio amp available at Mouser Electronics. Replace the 35V 4700mF caps with 50V 4700mF caps. You will only have enough space on the top of the PCB for one of the larger caps. I mounted the other on the circuit side of the board. Note the polarity of the original caps and respect it in their replacements. The fuse is a 5 X 20 medium speed slow blow 250V 2.0A glass fuse.

Blew a fuse what kind dose it take is it a slow blow fuse or fast blow one,i took out the old fuse and it reads le.3a/250v is it a 3a or .3a


It is a 3A/250V fuse, also known as a 6A/125V fuse.

Power amps generally have slow blow fuses.

Fuse blows, replaced the two capacitors and it still blows fuses... sub is fine and not blown...what else could it be??


If your sub is made to be used in other countries check to make sure it hasn't been switched to a different voltage.

AR1 Subwoofer Keeps Blowing the 5 Amp Fuse


Well, so far so good. I reinstalled the newly repaired amp and fired it up and so far, so good. Ran it through about an hour of fairly intense break-in tracks and then ran it through about 2 dozen power up and down cycles to try to get it to fail (better now than a month from now and have to fight them on backing it up).
