John,
It's hard to say what caused the failure. Could be customer abuse or
underated speakers, especially since it is my understanding that the
audio circuit still works--just open voice coils. Check out the specs on
the amplifier IC and the voice coil ratings. Ask if customer hooks up to
external spkr jacks, if so equiped. (Not worried about an external
load--just an external amplifier, perhaps.) Sounds to me there is a teen
involved and the speakers just got tired and turned in their resignation
after 8 months. To be honest, I would be tempted to put a resistor,
about 2 ohm, 10 watt, in series with the voice coil on each channel.
Would limit the power, but, oh well...
