AR1 Subwoofer Keeps Blowing the 5 Amp Fuse

No power going to one subwoofer on my AR1 Speaker. Took off Sunfire amp off back. Found three fuses. Bottom small 5 Amp 250V blown. Replaced it and it blew immediately upon turning on power. Tried again. Same result. Any ideas? Thanks.

    These subwoofer amplifiers were built by Recoton using Bob Carver's Sunfire technology. When Audiovox bought Acoustic Research, support for the AR1 and other HiRes speakers ceased. I have the same problem but haven't found anyone who can repair these amps. I'm hoping someone on Fixya can offer a solution. Mine spent the better part on two years in a repair shop before he gave up. His guess is a manufacturing flaw, but I have no evidence to back that up.

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).

I had the exac same issue. It started out with buzzing sound, but then quickly evolved into blowing the main 250V 5 Amp fuses immediately. I sent mine to ABTechservices.com and they found some blown resistors and leaking capacitors. I'm waiting to get it back (shipping to me now), but supposedly they have replaced and tested and all is working well. I'll let you know how it turns out.

The price they charged me, including return shipping was $187.50

My subwoofer keeps blowing the 3 amp fuse on the main power supply


There's an overload in either the power supply section or the amp part of the subwoofer. Overloads are mostly caused by a semiconductor that has shorted (acting just like a piece of wire). Transistors are easy to test with a multi-meter in this condition. For when you put the Ohm meter probes on each leg it will act like you are touching the probes to just one leg.

The fuse keeps blowing as soon as i power up jbl pb 12


You have an overload in the power supply or main amp of the subwoofer, often caused by short circuited transistor. Check this out by putting an ohm meter probe to each of it's legs. If it acts like you were touching the probes together you have found a guilty part.

Fuse blows


Both 3 or 4 amp slow blow fuses are suitable replacements for the 3.125 amp subwoofer fuse.

It could be that the subwoofer is blowing the fuse because the one you installed was not slow blow.

But, more likely is the subwoofer has a short in the power supply which is causing the fuse to blow.
