Whats the benefit of having a 90 Amp alternator, over an 80 Amp alternator? I changed mine to a TT, and I was wondering what the big diffrence is. Im sure the TT needs more charging power, but is there a benefit on having it in an NA in the long run. Long run meaning larger stereo equipment.

 

yep, that's pretty much it. Extra breathing room for your larger stereo system.
