box not work anymore, (but I can hear woofer speaker in box). If it's due to a computer driver, how does it get to be fixed?
Previously used/connected larger older speakers just fine for years, now no speaker(s) work, even originals, connected to it. Capacitors? Drivers? How to fix?

Hi there,
First do a test on another device like a cell phone or walk man. You can also test the speaker with a battery. A sub with a different Ohms can also damage the amp. a 4 ohm speaker will drop lower than 4 ohms.the average is 4 ohms because the impedance goes up and down depending on frequency.
So if you say 4 ohms is the max. you don't want the 4 ohm speaker going lower and stressing/damaging the amp. Also have a look at 'impedance curve' and you will see the line changes from whatever ohm is in the specifications a 4 ohm speaker might drop well down to 2 ohms and some people would either destroy their amp faster, or cause their protect mode to turn on, or cause their protect mode to grow more and more sensitive until the receiver doesn't want to work with 8 ohm speakers ever again.
