No it's pronounced BASE, but spelled bass. I was talking with my sister on facebook about me getting my system in and I said bass, and she was like huh? then I said you know makes boom boom in the car??? And her being the blonde that she is was like "ohhhh you mean base cause bass is a fish."
I tell ya I bout pissed myself on that one.
So um yea spelled like the fish, but pronounced like the board.
