I've been trying to get a set of AR3 Hi rez Sunfire amp powered subwoofer speakers fixed.
One of them blows the fuse on my amp and both of them no longer have the STANDBY power feature, leaving the amplifers on all the time.
I can't find anyone with a schematic for the AR Sunfire amplifier or a parts source.
I've tried to contact Acoustic Research, Recoton, Thomson as well as several amplifier and speaker repair facilities in Florida with no luck.
Any suggestions or help would be appreciated.
I'm having the same problems but with the AR5's. If there has been any progress in this matter I'd really appreciate any help finding a schematic for parts order or in house fix. Thanks much

I had the same exact issue with my AR1s. Found ABTechServices.com that was able to repair it for about $187.50 with return shipping included. Apparently there were a couple leaky caps and some bad resistors. My guess is that when Recoton built these amps, based on Bob Carver's Sunfire technology, they used defective capacitors. These, in turn are probably blowing the resistors and possibly some of the other components.
It's not a solution but I have the same problem. I found two transistors shorted in the subwoofer amp, a 2SC3281 and an IRF640. I replaced them but there is still a large dc offset in the output, about 10.5 volts. Without a schematic I'm kind of just fishing.
Just wondering if you were able to get any more info on this problem. My house got hit by one of Orlando's famous lighting storms a few weeks ago and along with about $1,000 worth of other equipment, both of my AR5's took a hit. They blow the 5 amp fuse immediately when powered on. So now I'm looking for some help with these as well.

Check to see who the manufacturer is. The Acoustic Research name was sold a couple of times. I think yours may be Recoton. If so, you may be able to get some help from them.
hello, the reason for the this is because theres a dead short in the unit someware i'd check the diodes first with a multimeter then the transistors then the resistors then the capacitors
hello the reason for that is there's a dead short somewhere it could be a transistors also check the diodes as well but make sure the power's off good luck
Some subwoofers can sense the signal on their input and will only start when there's enough signal for long enough time for them to turn on the amp.
Try seting the "subwoofer signal out" on your reciever a bit higher, see if it does the trick, if not, try it with some other source (e.g. an mp3 or CD/DVD player) plugged directly into the subwoofer. If it still doesn't work, there's some other problem with your sub (bad connection inside sub, sub amplifier problems, maybe there's another fuse for the speaker itself, try to check it out).
If it works well with an alternate signal source, the problem might be either in reciever or the signal cable that you use, but could also be something else.
You can go to Walmart and in the stereo/speaker department they have dash kits for different vehicles.Just read the box to determine your vehicle. Also, they have amp kits for different wattage amps, but if you had rather buy each item you will need, a Power Wire (to the battery 4g or 8g), a ground wire (to the chassey), a remote wire that should run to a wire from your cd player saying remote (any size is fine), speaker wire (14g or 16g is fine) a set of RCA cables, and if your cd player dosnt have RCA jacks you will have to have a converter.
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).
The first thing to always check first is the fuse. This will probably involve some disassembly but it is alwayst the cheapest fix and a constant issue.
I'm having the same problems but with the AR5's.
