When installing my speaker system, I got the speaker cables the wrong way round, plus in minus, minus in plus. According to the manual, if you do this 'cd image will be lost'. Unfortunately, due to this error my system does not work, I get no sound at all. The computer does not recognise the system when it is plugged in, despite the fact It has a sound card installed. Has anyone got any ideas to get around this problem. Thanks.

From the plus(+) of the speaker output on the amplifier run a cable to the plus(+) on the voice coil of the first subwoofer then follow thru with the same cable to the plus(+) of the other subwoofer.
From the minus(-) of the speaker output on the amplifier, run a cale to the minus(-) of the first subwoofer then follow thru with the same cable to the minus(-) of the other subwoofer.
This will make your amplifier run @ 2OHMS and provide you with 350 Watt RMS which will work fine even if you run your subwooffers free air(without a box))
hope this helps
an easy way to identify polarity is with a 9 volt battery --connect the plus and the minus of the battery to the speaker terminals ---if the woofer pushes out--then the plus of the battery is connected to the plus of the speaker --if the woofer goes in then the plus of the battery is connected to the minus of the speaker and then mark it with a black dot on the speaker to indicate its the negative for the speaker and now you know which is plus and which is ground--enjoy
I assume this is an active sub. The amplifier has most likely failed. You have proved the signal source is not the problem, well almost if you can sucessfully connect the aiwa sub to another amp then we will know for sure. Usually amplifiers fail with an output device short circuit. The hum you here is the power supply direct on the speaker, I would not leave it on for long or speaker damage may ensue.
the plus is postive usually red and the minus is negative usually black. make sure you dont mix them up when you are connecting them to the acutal speaker or you will blow it and it would be useless then.
You can check Both Crutchfield's learning center on subwoofer wiring diagrams and www.the12volt.com with their wiring diagrams. The crutchfield setup will be more informative for this type of problem. Just go one of the + to one of the - on each sub then wire the other plus's together between the subs as well as the minuses like between the subs and use the open plus and minus that u didn't just bridge. Then there should be just 2 wires a plus and a minus to the amp. Then follow the amp bridge wiring which should be found right above the speaker terminals it will be left plus to right minus or the other way around
