Couple small questions here. Whats the output on the stock alternator? The reason i'm asking is due to the fact that its starting to wine, or atleast right now thats where it seems like its coming from, and I'm running a system, nothing big, about 450 watts max, with a half fared cap. What is the max output with out overloading it. Also who sells a more heavy duty alternator so if I decide to go with a bit more powerful system? Thanks in advance. -Gary
