So I bought the rumble road speakers, i have a 2009 vucan 900 custom. Im going to install the speakers tomorrow or attempt to, im just a little confused about how to do it. Should i go straight to the battery with a inline 15a fuse? Should i use the acc port? And if i go to the acc port do i put a relay in there so the speakers shut off when i turn the bike off? seems like there is so many ways which is the easiest and best for the bike? THank you!
