Kia Optima High Output Alternators

Sharp styling made the Optima a favorite canvas for custom builds, and many of those cars carry big subwoofers and serious amplifier power in the trunk. A Kia Optima high output alternator from Mechman, in 240 or 320 amp form for 2011-2020 models with the 2.0L or 2.4L engine, gives loud builds the current to keep bass clean.

Feeding a Bass-Heavy Trunk

When an Optima trunk fills with subwoofers, the amplifier draw on long bass notes can pull voltage down fast, causing dimming lights and an amp that runs out of breath. The 320 amp unit is the logical choice for a multi-sub, high-wattage build. The 240 amp unit fits a single amp and sub setup with room for lighting.

Show cars also tend to run accent lighting and display screens while parked with the doors open, and the alternator has to replace that energy on the drive home.

Both are Mechman high output alternators for 2011-2020 Optima sedans with the 2.0L or 2.4L four-cylinder, using a single wire turn-on connection. Confirm your year and engine in the vehicle finder above the products.

Twin Platform and Wiring Support

The Optima shares these units with its platform mate, the Hyundai Sonata, as well as the Kia Sportage. A 320 amp Kia Optima high output alternator deserves heavy-gauge charging cable, which you will find in our amp wiring kits, along with a strong battery from our batteries.
