No long interconnects, sure. There seem to be number of wireless devises that would make a crawl tested location for a single sub very easy. You’d still need a nearby VAC receptacle.
Over years of home and pro subwoofer use I’ve never heard a sub slow to react to signal even with 100’ XLR. I have experienced poor subwoofer presentation.
Consider you’ll be subjecting the source signal the time it takes to pass through the additional amplifiers I/O stage as well as any of that amplifiers frequency limitations.
All the best with your search.
