Ps-1200-A sub woofer will not power up


Probably a blown fuse. If there's not one on the face of the amp, pull the amp and check for one next to the power cable.

Mirage LF 150 Sub Woofer. sub not working


within the sub amplifier is an electronic amplifier, that is shorted and blown a fuse. This is all internal. If you can dismantle this module, I suggest do so and any electrical/electronic individual will identify the part needed. you could also check on a replacement module-complete.

Sub-Woofer blowing fuses.


You should open it up and look for a short. Usually, an exposed wire is touching metal. Wrap the wire with electrical tape and look for a ground wires that are loose. That will blow fuses too.

Keeps blowing fuse in woofer


Seems like the wires inside the woofers are crossed. Open the sub and make sure that there are no bare wires touching. If everything seems OK then the circuitry inside is blown.

Onkyo sub woofer


You will only blow fuses and resistors if there is a short of some kind you can change fuses, resistors and capacitors all you like if you don't find the short they will just keep on blowing. It maybe something as small as a bit of conductive material or fluff or dust on chip board wipe board down make sure it is clean (a clean toothbrush is perfect) and there are no signs of burns on either side of the chipboard befor you change anything. If there are burns or greenish build up clean them with some metho or water on a cloth not to damp though and make sure Burn or corrossion hasn't taken off the protective layer on the board.
Then try new fuses. Hope this helps you
