Default Subwoofer (ED) not working correctly?

Last night watching a movie I noticed the Sub wasn't putting out sound. Also noticed several times it clicked back and forth.

Light showed green, but no sound. Tried a few things and it never came back on.
-Turned the auto/off switch to off and let it sit overnight.
-Flipped it on today and turned on the radio. Sub clicked on and seemed to work OK.

-Questions. Is this a sign that it's going bad? Could it have been overheated? Should I leave in "off" until I'm ready to use it and then switch to auto?

Thanks.

What type of sub is it?

Sometimes the auto on feature goes bad, and there needs to be a heavy amount of bass to get them to signal on. Not sure, maybe that's what's going on with yours. If it worked when you turned it off, then into the on position, I suspect the auto on is not working properly.

It does have an auto feature. It does not have an On feature. I'll try the eD post, but am skeptical on those endless threads.

When you say "clicked back and forth"....what exactly was clicking? The auto on/off circuit?

This might just be a case of the auto on threshold not being reached. If that is the case try turning down the subwoofer gain control a little and raising the bass level control in the receiver(which usually ranges from -12 to +12). Also, be sure you have all of your speakers set to small/80hz(or higher) as well.

I don't know what is clicking, but I hear an audible click. It does sound similar to when the sub initially activates, but I don't know if there might be another cause of the clicking.

I have not recently changed any settings to cause this issue, so I doubt it's the threshold not being reaching. I also boosted the sub level in the channel control to try and get it to register and click on, but no go.

I did some more tests and have discovered that it seems to work just fine, but only for a couple minutes. After this time it clicks a bunch and the sound eventually cuts out. The light remains green seeming to indicate that it's getting a signal and/or it thinks it's On.

Maybe my next question should be if there is a good replacement amp I can buy and what size I should try for.

I hate to keep bumping my own threads...but are just not that many active users here anymore? I was really hoping for some first hand experience/advice on this.

I think I've found a plate amp from parts express that might work....but am not 100% sure this is the problem or the best solution.

Anyone out there?

Try AVSForums, which has a larger active base of DIYers that have attacked just this situation with their old eD subs.

If this is all at low/moderate output levels I'd say its the amplifier. Which model ED is it? They had everything from 200w to 1200w IIRC?

Yes, this is at low/moderate levels. It's an eD A2-300, pretty sure it's 200w.

I was considering replacing the amp with this one. http://www.parts-express.com/dayton-...ifier--300-803

But, I've never done this repair before and am not sure what to expect. Probably have to modify the cabinet.

Doesn't that eD A2-300 have binding posts for speakers in, out? If so, another option could be to use an external amp and connect via speaker wire? Just throwing it out there in case it is a viable option.

Edit: If you search on this topic there are posts on other forums about amplifier failures, so chances are your amp is on its way out, if not so already. How much are you willing to spend to fix it versus buying something else? For example, BIC America F12 12-Inch 475-Watt $203 AMZ

It does have posts...would that option be better somehow? Cheaper?

That Dayton is $140 If you had a spare amp that you could use, then you could use that to drive your subwoofer instead of getting another plate amp. Not sure that you can buy a new amp for cheaper than the plate amp, not something I am familiar with.

I had edited my previous post with the BIC F12 option, but got interrupted in the middle of that edit and it never got posted until after your reply. So if spending that much money on a repair, perhaps you should just cut your losses and just buy a new sub? That BIC is a close match, 150W RMS and 475W peak.

Do you have any spare 12" woofers laying around? Maybe a friend in car audio that has one? If so, I'd try to pop that in first. Hate to see you spend $125 on an amp just to find out the problem is still there.

If you do replace the amp, you can do what the last poster suggests. Leave the current amp in place but modify it somehow so can get the signal (2 speaker wires) from the new amp THROUGH the old amp and to the woofer. This can be as simple as drilling an 1/8th hole through the plate and running a pair of 16g wires though it. Then just dab a little silicon over it for the air tight seal.

The PE amp has the added bonus of the back panel being covered. That is important as the backend of amps can over serious shocks when plugged into a AC outlet.

If you have any specific questions about any of this always feel free to pop into chat at powersoundaudio too. I'm usually in there from about 9am to 8pm 7 days a week.

I like the idea of going easy/new. But...what can I expect in performance from the BIC? It's awfully cheap, which isn't bad, just makes me nervous. I've had the eD for so long and really liked it I wouldn't want to drop down a bunch in quality.
