Infiniti Q70 High Output Alternators

A quiet cabin exposes every weakness in a sound system, which is why many 2014-2019 Infiniti Q70 owners eventually add a processor and real amplifiers. This Infiniti Q70 high output alternator is the 400 amp Mechman unit listed for the 3.7L V6, built so a serious audio build in a luxury sedan never runs short on current.

A Quiet Cabin Rewards a Serious System

The Q70 is a midsize luxury sedan with a well-insulated interior, and that insulation makes it a natural home for high-fidelity audio. Typical builds keep the factory head unit and add a digital signal processor, component speakers in the doors, and an amplifier rack hidden in the trunk with a subwoofer behind the rear seat. Dynamic peaks from a system like that pull hard on the charging system, and voltage sag shows up as soft bass and distortion at volume. An Infiniti Q70 high output alternator keeps the supply steady, so the amplifiers deliver the output you paid for.

Matching the Alternator to the Build

This billet unit is listed for 2014-2019 Q70 models with the 3.7L engine; confirm year and engine in the vehicle finder above. The same alternator appears on our Nissan NV2500 page. Mechman high output alternators pair naturally with heavier power wire from our amp wiring kits, and a fresh battery from our batteries collection rounds out the charging side.
