Hey guys. New seadoo boat owner here. Looking for your suggestions on what type of battery's and stereo to run. I bought a jl 700/5 marine amp and 10" jl marine sub. What's the best type of battery switch, type of deep cycle battery to run? Also, any of you guys fit another set of 6.5" speakers in your boat? It seems pretty tight. Any suggestions ideas would help. Thanks guys!!!!
