I've been wondering where I could mount rear speakers in my convertible, and I really REALLY like where you've mounted your rear speakers Vikki -- so thanks for the idea, and the great photo's.
I'm going to have to wait a few years to do it though; my kids are just 3 and 1 years old, and I KNOW they'd be poking/pushing on the speakers non-stop , especially when they're vibrating.
