Question about Audio Players & Recorders
I took the power board off the troublesome subwoofer and reattached another powerboard of another Jensen SPX-17 subwoofer and it worked perfect. So I knew it had to be something inside the trouble SPX-17's power board. I took it apart to see if any wires were loose or not properly attached to the laeds and everything was solidly in place. Why is my subwoofer only pumping out about 10% performance volume level. I even configured the sound level on the amplifier/receiver to a 10+ level and it made no difference. Any ideas Thx; Gary
Gary, If you have the subwoofer open, what did you keep from measuring the voltage of both power supplies? And while measuring, why not put a load on both, and see what current they can handle?
When the error moves with one component (power supply) the error must be there. Without a multimeter, (I have several, but I'm not close to the power supplies) you can't tell if the power supply is working to full performance. So start there.
Just try to find out, if a part of the rectifier is defect (one diode) It won't be possible to point out what is wrong, if you can't measure on the device yourself.
