Just curious. I am installing a stereo (cheap Pyle) , amp (150 watt X2 or so) and speakers(2 monitor marine 300 watt peak) and other than running the engine, fishfinder and tunes (maybe a couple lights at night) and charging two batteries will I need a bigger alternator? I am going to install another battery and 3 position selector switch to prevent starting issues after beached music time. I am considering rebuilding my existing Paris Rhone stock alternator also but need feedback before doing so.
Thanks guys,
