Two questions guys: (1) Could somebody please inform me what a 355 alternator's ampere rating is? I'm thinking of installing a 500W x 4 channel amplifier as part of a stereo setup, and I wanted to know how much reserve current capacity the car has, so as to determine if it can support the amplifier output. (2) parkerfe had posted the following comment, when discussing the rebuilding of alternators: "The two rebuilt alternators made such a difference in the power delivery on my Boxer, it's like driving a different car! It just revs and revs with no end in sight where before it starting getting flat at 6k rpm or so..." Can somebody explain the connection between alternator capacity as it relates to effects on the power curve? In other words, how can I expect using up 'excess' alternator capacity to affect performance. Many thanks.
