Sub turning off, co-worker's dilemma

[allstar780]

A co-worker of mine asked me about an issue she's been having... basically she has a denon receiver (doesnt have the model number, will update when she gives me it) and a sub she said only has speaker wire inputs (she doesnt know anything about it... obviously it's some type of passive sub... will update) and basically the sub output on the receiver is shutting off at a certain volume (i'm assuming that the amp doesnt have the power to drive the sub or there is some sort of short)

basically I need suggestions for what to try if she drags me to her house to try to fix it... obviously i'll check and re-check all connections, what else?

if you want to have sex with her, buy her a new sub.

I’m hoping I get the correct meaning from the information you (she) gave us – If the sub at loud volume is causing the receiver to shut down, that means the protection circuitry is doing its job of kicking in to protect itself. If it’s the sub that turns off, perhaps it has its own protection circuit. Look for a reset button or maybe even a fuse.

I would also wonder if she is running it off of a “b” set of speaker terminals, or how she has it set up. Does she have her “satellite” speakers running from the sub, and if so, are they shutting off too?

If the receiver has a regular RCA subwoofer out suggest a cheap used power amp she could dedicate to her passive sub. Use the receiver for the regular speakers then, and she should be set.

Well if she wasn't twice my age, married with children, and a soon-to-be grandmother, then maybe.
