Mechman high output alternators · Authorized dealer
The A3 hatchback turns its cargo floor into a natural spot for a subwoofer enclosure, and its 2.0L turbo makes it a favorite for road trips with bikes on the roof and devices charging inside. An Audi A3 / A3 Quattro high output alternator from Mechman delivers 400 amps for 2009-2013 models, so the hatch build and the travel gear share plenty of power.
A hatch-mounted sub sits close to the cabin and gets pushed hard, and every bass note draws current. Add a cooler, an inverter or camping lights for a weekend away, and the charging system can fall behind. The 400 amp billet alternator listed for the 2009-2013 A3 and A3 Quattro with the 2.0L engine gives you a wide margin for those loads.
Many A3 drivers keep the car for years and add equipment gradually, so starting with a high output unit means each new addition does not require another charging upgrade.
This is one of the Mechman high output alternators that also fit related 2.0L cars like the Audi A4 and A4 Quattro and the Audi TT and TT Quattro. To be sure about your car, select your year and engine in the vehicle finder above the products.
An Audi A3 / A3 Quattro high output alternator should be paired with charging cables sized for it, which you will find in our amp wiring kits. For plug and regulator needs, check harnesses and regulators, and see the full Audi alternator collection for more models.
