I was just thinking about the speaker holes and thought if you had a standard, put them where the two guages go. That way if you were to remove them, you could put guages in, no holes! Also, for the guys who are worried about the fairing mount mirrors, this is a way to cover those holes if you remove the mirrors, if ya don't like the mirrors or bought a bike with them and wanna remove the mirrors!Vis versa, if you want to add tweeters and don't plan on mounting fairing mounted mirrors, borrow a mirror template and drill the holes for fairing mirrors. Then mount you tweeters. If you decide you don't like the tweeters remove them and install fairing mount mirrors, the holes are already there. Tweeters can come in handy! Just an idea..
