Good chance a shorted diode on the other end of the pcb where the big wire harness connects.
Four little 1N4001 diodes (D10 through D13 I think) and Two diode bridges (the black sqares standing off the board on four legs).

You need a meter to check them. Any one of those six could be the problem. If it's one on the 1N4001's
then you should replace them all and upgrade to 1N4007's.

I just upgraded some some parts on my ADA880 sub pcb today. Love the sound of this system no longer use it with my computer - have it hooked up to a DVD player with digital out. So basic but so awesome.

ADA 880 subwoofer schematic diagram


Mounting is not so critical,


• If it is the same size of the original , replace as it was

On most, it is perpendicular to the PCB


• What important is the polarity,

positive side goes to positive, same with the negative.

Mission m-cube sub fuse keeps blowing


If you have replaced with the correct rating and the fuse blows off then you will need to check for higher current drain in the sub woofer or the network. After replacing the fuse load up the subwoofer slowly, reduce the bass and as you increase check at the point the fuse blows off. Now we need to analyse if the rating of the amplifier you are using is rated for the subwoofer. If your subwoofer has a higher rating you can increase the rating by about 25% and check again. Some amplifiers give a very higher voltage on full bass which could result in such a condition. Moderate this and check again. If the fuse stays Ok you can continue with this new rating.Otherwise the output of the amp at higher volume needs a confirmation. Hope this helps. Good day

My Ada 880 speakers work fine, but the subwoofer isnt making any noise....it doesnt seem like its getting power but if the speakers work id assume the fuse is good right? i cant seem to find alot of...


Hi there bud, this could also mean that something in the Subwoofer has blown or shorted, the best thing to do is too take it back too the shop where you bought it and ask them too replace it .its not worth opening it up yourself and losing the warranty...
Happy new year . Hope you come right :)

Fuse on subwoofer keeps blowing


Subwoofers draw a tremendous amount of power. With the amount of heat generated by amperage flow and the movement of the voice coil, you may have burned out the coil. Do a resistance check across the coil. Easy check? Temporarily attach another speaker to replace that one. Use LOW VOLUME and slowly work the vol up,and, if the fuse does not blow, it's the other speaker.
