I have had the boat for 2 years with 4 in boat speaker, 1 woofer with 1 battery and everything has worked great. I just put in 2 tower speakers and took it out for a drive and the gauge said I had juuussst over 12 volts. I typically don't sit and listen to music more that say 20 minutes and always care and emergency start pack. Is the 12 volts alright or does it have to be higher?
