Power upgrade

[ryno1978]

Thinking of upgrading the sound system in my 2004 utopia 205. It has the mercruiser 240efi in it. It currently has 2 speakers and a head unit from factory. I would like to add 2 more speakers in the stern, a sub and wake tower speakers but obvious concern is power draw from an amp. Is there a way to get more production from the engine? Does it have an alternator? If so, do they make larger ones? Any thoughts or suggestions would be welcomed. I am looking at also putting a 2nd battery dedicated to the system but want to be able to charge it while under power without burning anything up.

I'm not sure what your alternator output is but my 2001 Islandia has the same motor, 240 EFI gen 1, and it has 6 speakers. I recently replace it with an up grade, blue tooth ect along with new speakers with led lights. I haven't seen any problems.
