Email straight from Mike Singer.

The upgraded unit that I offer for your vehicle is a 275A. This alternator is a direct bolt on design for your vehicle and would be plug and play (the factory plug would go into it like the OEM unit) This alternator includes my overdrive pulley to boost the idle output (this will spin the alternator faster at low RPMS to boost idle output by around 30 to 40A more (170-180A idle). This sized model would be more then suffice for your current draw of the sound system you plan on running.
