The alternator puts out ~14.4V when running.
You'll tend to see higher end companies rate their amps in the 12V range. They will generally produce significantly more power at 14.4V.
Companies that rely more on marketing like max power, etc... will tend to rate their amps at 14.4V.
This is why a 200x2 amp from PPI, MTX, etc... will cost significantly more than that 200x2 Jensen, Boss, etc... amp.
