At my wits end. Not having a sub is the worst. I have a Sony SA-WM40. I couldn't get any sound out but the speaker does move slightly. It does come on but very rarely and then quits. Used a different cable, no change. The sub does get a signal because it comes out of hibernation. Tried the level and crossover knobs as well as turning the hibernation off.
I have taken the speaker out and measured 7.21 ohm's so the speaker is still good I guess. Solder joints look good. Free movement of the cone. Circuit boards look good. No obvious discolored components. Fuse is fine. Is there any further checks I can Make? I've been to the end of the internet and back for help.
If all else fails, can I use the enclosure and speaker and replace some/ all the electrical components and save some $$$? If so how do I know what to get? Can't afford a new sub at this point.
Thanks, Frank
