you are talking about a 'system'...a stereo system?
it's pretty normal with vented batteries. i suspect you are also cycling your battery fairly heavily with the addition of your system, but then again, i don't know what sort of wattage/amperage draw that your system has. clue to another problem? maybe.
clean the corrosion with a big cup of hot/warm water and baking soda. and just remember that you are dealing with ACID and that it IS corrosive, so using a brush or whatever is not as safe as using the hot water/baking soda. honestly, not telling you what to do or anything, but i hate vented batteries for the same very reason. after i switched to my Optima, i have NEVER had to clean corrosion off of battery terminals, or anything else that usually suffers. just my $.02USD.
