Second Battery, Is it time?

Starting out or in a daily driver you may get by with stock power, but as the addiction we call car audio or “being a basshead” takes hold it wont be long until that 500 watt system just isnt enough.  Dimming of headlights and other common warning signs should not be ignored and puts your vehicle and equipment at risk.  You can make changes such as adding a High output alternator and a second car audio battery to your system.

Before jumping on that car audio amplifier upgrade you may want to start with a second battery.  Adding a  car audio battery to your system can prevent straining your system or equipment.   car audio Amplifier can produce bursts of power output while playing certain songs and tones.  As you continue to upgrade you may choose battery with additional amp hours, or even going as far as adding Lithium Car Battery.

Refer to the diapgram for proper wiring for adding a second battery.

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

After adding a second battery you may choose also to do what’s referred to as “the Big 3” and adding a High output alt.  This will also reduce the load on your system and common car functions.
