Tweeters didnt work so i took out the old dead fuses (312 3/4a 250v) and replaced with the same kind minus the 312, cause i had no idea what that meant. The tweeters now work! The new fuses were the fast blow kind so......if they work now, they should be good right? Also what the hell are the fuses for, just so you don't blow the tweeter?
