Buyer’s Guide: High Output Alternators

Proper amperage is key to a good electrical system.  A High output alternator may be your next step in your car audio journey.

If using mutiple alternators you may need an alternator bracket.  Good practice is to upgrade to the “Big 3” when installing your new alternator.  The BIG 3 may sound intimidating but it breaks down to a few steps.

As always we recommend you consult a professional before you begin.

Start with a good wire, we recommend using 1/0 Gauge OFC Power and Ground Wire with anything electrical.  Better to start with a good connection rather than having to pull and re-run wiring everytime you upgrade.  Save up and just start right from the beginning.  You will also need a few Ring Terminals/lugs.

When adding any grounds to your electrical be sure to pick a good position and prep properly to ensure a good connection.

  1. The first connection will be adding wire to connect your High output alternator mount/bracket to the body/frame of your car
  2. then connect you engine block to the car body/frame
  3. finally, connect the battery to the car body/frame.


Find the right balance between quality and budget.  Buying products that are cheap and not quality could result in replacement and expenses in the future.  Best Practice is to start right and not have to do anything twice.
