Question about the SP4's

Well just cuz you have one alt doesn't mean that you can't add more batteries..

Or am I missing something? Cuz you could build up a bigger battery bank

not to thread jack, but i didnt want to start a new one..i've got a question also. Im looking for the actual outside diameter of the sp4 15". i see on the site that its 15.625, but does that include the rubber gasket or is that just the sub basket?
