Power indicator doesn't show power is available when plugged in
I've been using the subwoofer and speakers as an output device for my iPod. It just stopped working last week - when the unit is plugged in, the power light doesn't illuminate and there is no sound. Is there a fuse on the inside that I might have to replace?

There is no fuse inside, but, consider, a replacement, if you have warranty, but, unfortunally, there is no other way , beside take to a repair shop, and have it fix there.
you may have to secure your speakers with a UPS too, depending on the fluctuation on energy at home.

You don't say what make or type either of the appliances are, so I can only answer in general terms.
First look at the back of your stereo system and see if there is a dedicated subwoofer output. If there is you should be able to find the correct lead between the two units by looking at both the connections. If the subwoofer is a powered one. IE with a mains plug on it, you have to plug it into the mains before it will work at all. The connection points also then need to be hooked up to the amp. If it's not a powered subwoofer then your main left and right channels speaker wires need to be split into using the subwoofer terminals provided. Another set of terminals on the sub, then lead to the main speakers.
Lastly if it has a dedicated subwoofer output, then the amp might have a setting that turns this on or off. So you might need to switch it on.
Definitely need more info - such as type of amplifier or receiver, how many speakers you are running, whether the subwoofer is powered or not.
As a simple test procedure: Disconnect all speakers and plug in a pair of headphones. Get a strong audio signal? Good, move on. No signal or week signal, you have an amplifier issue before the audio even gets to the speakers.
Next: Disconnect all speakers, turn the volume down, and connect one speaker to the left output channel. Slowly increase the volume. If that works, do the same on the right channel. Everything OK? You're putting out enough gain on both channels. Sometimes one channel goes bad. You can still listen to your sound in mono moder, or drive two speakers from the single working output. Not stereo, but dual mono. Move on.
Connect left and right speakers but not the subwoofer. Repeat the test. Whatever is left is probably the problem. If the subwoofer is powered, check the power supply or incoming voltage. If the other speakers are driven off the subwoofer or powered from there, that's likely the problem.
Are you using a voltage adapter of some kind to convert the ireland standard 220VAC to the USA standard 120VAC that this device uses? Over voltage can deplete an electronics life very quickly.
By the sound of the "thump-thump-thump" noise emitting from the device, you may have a broken ipod dock connector, or a short somewhere in the connector/wiring/device itself, or the ground has failed.
By the description of having to "tweak" your ipod to hear it, it sounds like you've slowly broken the dock connector. Check to see if it moves easily, or if you can hear anything loose.
This is more than likely fixable, but it's probably easier to replace the device than to fix a broken connector.
Hi. Check your speaker system with a different audio device like iPod or any MP3 Player using the same jacks. If the speaker system gives out sounds then nothing is wrong with it... if no sounds come out, then you know what I mean...
Try to replace the speaker of your sub-woofer... maybe that can fix it!
If your receiver has a dedicated subwoofer line level output, we recommend connecting your subwoofer to this jack. Most receivers will have just one (mono) subwoofer output, while quite a few subs require two inputs. You can use an RCA "Y" adapter cord , which is a cable with one female RCA jack at one end, and two male RCA plugs at the other. Some receivers require menu settings (such as "sub-on" or "front speakers-small") that must be made before the sub output will be active.
check the power cables on the amp and the inputs.isome time when ground cable disconnect the lioghts will light up any way. depending on the way ur vehicle is ground ed .toyota chssis r usually posite un like the norm which is neg.rating please
