which Cadence amp did you get? I've got the ZRS2002 and my pro80's ROCK! I've even managed to submerge it twice already due to stupidity and the amp is still kicking strong. Cadence told me even if I got it wet and it broke they'd still cover it under warranty. This is one of the brand names that Wet Sounds suggested and I called Cadence directly to find the right amp for the speakers and couldn't be happier with my decision.
