Mechman high output alternators · Authorized dealer
The 2011-2012 Infiniti G25 brought the G sedan's looks and rear-drive feel with a smaller 2.5L V6, and it attracts owners who want a stylish car on a sensible budget. This Infiniti G25 high output alternator is the 400 amp Mechman unit listed for that engine, a solid foundation for a first amplifier and subwoofer.
G25 owners often buy the car for the design and then make it their own with sound. The usual first build is an aftermarket head unit, a mono amplifier and a single subwoofer in the trunk, followed later by a four-channel amp for the doors. Even that modest setup can dim the headlights on bass hits once the factory alternator ages. An Infiniti G25 high output alternator at 400 amps covers today's system and the bigger one you will probably want next year.
The billet unit here is listed for 2011-2012 G25 sedans with the 2.5L engine; confirm year and engine in the vehicle finder above. The same alternator is listed for the Suzuki Equator. Mechman high output alternators are the charging side of the equation. For the rest, start with a properly sized kit from our amp wiring kits and consider a new battery from our batteries collection if yours is more than a few years old. Other models are available among our Infiniti alternators.
