Lighting Advice

I'll be shooting a project in a week or two and it involves staging a really large speaker stand. Speaker measures 5' tall by 3' deep by a foot wide. Kinda high end speaker stuff. Speakers are really heavy though (300+ lbs) and cannot be moved, so they're gonna be at a home where they've been installed.

Never having done any on-location product photography, I'm at a loss as to how to proceed. Any insight would be really welcome.
