[QUOTE="knil, post: 8445383, member: 667746"] Well I took the plunge and ordered a HO alternator and installed it the other day. I also took this opportunity to do my "Big-3" as well. I noticed that the factory wire coming off the B+ side was not going directly to the battery but was instead feeding into a fused/relay box in the engine compartment before feeding back to the battery and then another heavy gauge wire was running from the battery to what I guess would probably be the starter. I decided to run a new 4 gauge directly from the B+ to the battery as well as reconnecting the factory connection from the fuse box to the alternator. I just soldered the wire coming back out of the fuse box to the one that was running to the starter. It would seem to be fancy way of splitting the audio system power from the rest of the car's electrical system except for the fact that the new 4 gauge wire run between the battery and the alternator creates a direct short back to the factor connection going to the fuse box. I can see why some people choose to go with an inline fuse between the alternator and battery since it looks like the original factory connection was providing this protection previously. I already had 4 guage going between the negative battery post connection and the body and I made another 4 gauge jumper between the body of the car and the engine. I expect that will get a few virtual fist bump since I can now claim to have both feet in the "big 3" club as well as the HO alternator upgrade club. With all that said, back to my original issue that lead to the creation of this post. I suspect the stock alternator was in its final death spasm from about 5-6 years of abuse. After performing the upgrade above, I had forgot how bright the headlights must have been back before installing the system, and it is refreshing not having other drivers flash their headlights at you because they you were doing the same to them during loud bass hits, LoL.
