twanj Posted July 2, 2015 Share Posted July 2, 2015 (edited) I have a KSW12 subwoofer that has been amazing but apparently no longer gets power (the green light by the logo never turns on). I didn't realize it, but there's a fuse on the back that can be replaced. Underneath the fuse hole, it says "1.2A 250V". The fuse is 1.25" long. When I was first searching for them online, I could only find 1A, 2A, or 1.5A fuses it seemed. If I google for them I see one "Slo-blo" fuse at Amazon http://www.amazon.com/Cartridge-Fuses-250V-1-2A-Slo-Blo/dp/B005T8M1Q4 Other results seem to be for 100 quantity orders. They don't have this fuse at my local hardware stores. Is the above the correct fuse/Does it have to be exactly that? What other specs do I need to be aware of? From reading another thread, it sounds like this may not be the issue & the fuse will immediately blow again? Is it worth spending $13 on a fuse or better to put that towards a repair or a new sub? (I'm paring down from a 5.1 system. It's only stereo right now & plenty powerful at my new place with terrazzo floors but I figured the sub would be nice). What repair options are there? THANKS!

derrickdj1 Posted July 2, 2015 Share Posted July 2, 2015 Welcome to the forum. I have had a couple of subs that I had to replace the fuse and both times the fuse blew. There were problems on the board. The question is why did the fuse blow? Quote Link to comment Share on other sites More sharing options...

twanj Posted September 14, 2015 Author Share Posted September 14, 2015 I found a 1.25A 250 volt fuse locally, can I try that instead of the 1.2A 250V fuse that the sub states on the back, or will that cause problems? Quote Link to comment Share on other sites More sharing options...

More than likely, yes. Thanks for the response! What's the next step? Is something like this worth repairing or is just buying a new one ($450 from Best Buy) a better option?

CECAA850 Posted September 14, 2015 Share Posted September 14, 2015 Y0uo can buy a plate amp and adapt it to that box or shop for new. If you're handy, there's building as an option as well. Quote Link to comment Share on other sites More sharing options...
