Can anyone tell me (or make an educated guess) how much extra power is available from the 2003 Sonata (V6) while it is running? I know that the alternator is supposed to supply 95A @ 13.5V and that the battery is 68 Ah but I don't know how much power is being drawn so I can't tell how much slack they built into the system. Thanks.

Yeah, I checked that out already. The problem is that not everything is marked so I can't get a very accurate measure of how much power, other than that for lighting and audio, is being used. Thanks though.
