2013, wasnt moomba using the Kicker DX600.5 amp maybe for in-boats and woofer? At least a 5 chnl of some sort, right? If so, there is no fuse just for the woofer. Even then, the woofer amp will have a larger maxi fuse close to where the amp power wire terminates to the main switch or a BUB bar. Wont be a small automotive like fuse.
