Speaker tube mounting options

I think I’m about to order the Boss ATV25B speaker tube system to have a little tunes out on the trails. Don’t need anything killer, I’m sure the quality will be good enough for me.

It comes with two velcro straps and HD zip ties. But we are very limited to how we can mount without a true front rack. What are you guys doing to mount speaker tubes and still be able to utilize the front storage / ice-chest. Any suggestions?
