Hello,

I am preparing to put a basic sound system in my boat. The system is by Lowrance Electronics Lowrance SonicHub | Marine Audio Server - LOWRANCE | Marine Electronics

The system only has two speakers and each speaker is 4 ohm 200 watts. The system comes with a pre-installed amplifier but my hearing is less than great. What I am wanting to know is what amplifier size would best meat my needs? I know this is a rookie question around here but I know absolutely nothing about audio systems. If you have a product in mind that would work for what I am looking for, by all means post a link.

Thanks,
Brian
