Back in high school, my rock band had a gig, and I decided to try stacking two speakers under my Peavey Centurion head, all 130 Watts into two 15" PA speakers. Of course I forgot that I was on a short leash, and pulled the head down onto the ground. It just kept working and I left it there until we were done.
Today, I just wrap an old bike innertube around each speaker, and use it to tie everything down: Amp, gadgets, etc. It's also handy for carrying everything into a rehearsal or gig. Of course the real way to tie down a Class-D is just to get a combo amp. I'd get a combo, except that I really like my DIY speakers.
