Hi all, quick question. I was just curious when it is necessary to put in a high output alternator? I have a 500 watt RMS amp powering two 12" subs which according to my math should draw about 60 amps. The alternator in my Yukon just died and the regular replacement is a 105 amp alternator. Should I go with say a 140 amp alternator? Also there is a possibility of me adding a 50W x 4 amp for the speakers so please take that into account as well. Thanks for any help anyone can offer.
