if your interior gets submerged while crossing rivers/creeks/etc, you'll probably want to get marine audio gear....
all the major manufacturers make marine gear....mtx, kicker, infinity, clarion, sony, etc.
for the pioneer, you don't really need to worry about the microfuse problem if you have a competent installer that won't ground out live rca and speaker wires...
