Power amp for a passive sub

[blacksheep99]

Looking to help a family member. They have a sub and their old amp has failed. I'm after some recommendations for the replacement. I assume we could replace with a mono amp. The sub is a artcoustic Diablo compact sub. Any guidance would be appreciated. Thanks.

I believe this is the sub in question. 3 channel... presumably as it's got dual drivers. Slightly confused.

Nothing usual about that, it has one set of speaker terminals
Just look into a pro amp behringher a800 etc

Thanks. So how would it get the LFE signal from the AVR? Connect to the sub out and then amp to the speaker terminals?
