Re: replaceing internal fuse to mackie active sub woofer...
Hi There, you need to check the 3 fuses that clip onto the main amp board. You can access them by undoing the two screws that are on the top and the bottom of the sub. They have flat large heads and you will need a hex key to unscrew them. If it is one of the fuses that has gone it will either be discoloured as in burnt or you will see the metal inside has split. Simply replace these by pulling out the burnt out fuse and replace with a new fuse and hey presto you should be back up and running. If you need any parts for the sub or fuses then www.LondonSpeakerShop.com will be able to supply them (that is if you're in the UK). Also the offer a service of swapping them over for you if you really don't want to do it yourself. Hope this helps. Grant (from www.LondonSpeakerHire.com)

I am looking at the rear of a Creative sub as I write this. In general, the screws around the perimeter are the ones to remove but some others may have to be removed too. The internal electronics are mounted on a chassis which is held in place by internal hardware. Just proceed cautiously and remove only as much hardware as necessary to get inside
Did you find a solution? Dunno if it's much help, but I just today picked up some 501s - Series I I think - ugly heavy brown material grilles - but with a manual! No fuses in these, but booklet recommends installing your own in-line fuse holders (!?). Specifies a BUSS AGC-3 fuse for amps under 50wpc; or a MDL-2 fuse for amps over 50 wpc. Can be placed is series with either or the two signal wires. Very strange....
The fuse is internal. You'd need to take off the cover and look inside it. If you did that and took it to an electronics repair shop, they should be able to tell you where the fuse is by looking and help you find a replacement.
You could try disabling the auto-on feature or you could try a factory reset or firmware upgrade.
Swap the wires between subwoofers to see if its the wiring.
If its no longer under warranty you could try swapping the amp modules or the fuses, this will tell you if its a fuse or the amp or the driver... however by doing this you risk blowing up the second working amp or voiding warranty.
Last year I had an amp failure on my velodyne and it cost 250 for a 2007 replacement.
Open up the back of your gale 3080 and check the 2 fuses situated near the transformer.They look like 2 silver cylindrical shapes.Check that they have not blown if they have the will cost you around £2 to replace.Better than the 50 quid you will pay when you take it to your hi fi dealer to open up the back of it.
