Firstly, Bose speakers are fuckn brilliant. I have just purchased the Bose QC3 headphones, omfg they are amazing!
Also have the bose sound dock for my iPod also off the hook. Anyway its like holden and ford i guess.

Anyway I had Jensen outdoor speakers and they were fuckn awesome! they got rained on and everything and were fine. You could paint them so you could match your gutters or whatever you are going to attach them to.
I bought 5 of them from retravision for something like $800 and this was 5 years ago. To this day they are still going strong. They even put up with 3 years of fucked up pilbara heat and are still fine.
