Sup y'all, I was just wondering if anyone knows if SC put different output alternators on boats depending on the type of factory stereo? The reason I'm asking is I ordered the basic system and upgraded as soon as I got the boat and now it seems as if the charging system can't keep up. If I charge the battery's it will play fine for an hour or two and then it starts to go haywire ( speakers clipping or turning off and on). By the end of the day it wont even work at all but when I get back to the dock and plug up the charger within 20 seconds everything comes back on and sound great. Thanks in advanced Bama Dude
