I currently have two 12 lives at my bow, and one live 9 flush mounted in the dash. I have another 9 live loose right now and was pondering mounting it and the other 9 on a bbt dash mount, or just getting rid of the 9s altogether and putting one 12 at the console. From the current wiring standpoint, it makes more sense to just install one new 12 at the dash. Thought to get some opinions if there are reasons the two 9s, or the one 12, at the dash makes more sense. I am relatively new to Lowrance.
