Default Can I use a powered sub woofer with an amp via XLR?

Hi all. I have a Harmen Kardon HK 990 and my mate has a Behringer powered sub woofer which I would love to hook up to my sound system for a party. I just realized the amp has XLR output which the woofer uses but I don't want to blow up his internal amp. Can I safely use his powered woofer using the XLR output on my amp?

what are the INPUT specifications of the receiver circuit.

what are the OUTPUT specifications of the transmitting circuit.

You can't expect yourself nor us to be able to guess without information.

The XLR on the amp is most likely a pass through from the line level input, so it should connect to your sub OK.

The XLRs on the Harmon Kardon are inputs not outputs, So my guess would be no.

the confusion you cause by asking the impossible to answer question.
One says "yes", the other says "no".

I am referring back to Jack.
He asked a question but gave no information.

Gets three replies, all different.

HK 990 has pre-out RCA pins, connect them to the Behringer XLR inputs: plus (+) RCA pin to XLR pin 2, minus (-) RCA pin to both XLR pins 1 and 3, for Left and Right channels respectively.

There's nothing wrong with the question.
It's the lack of information that causes the problem.

Some one else has to go and find the spec for those In & Out to see if they are compatible.
