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.
***PLEASE NOTE*** All information on this site is for entertainment processes. Any guidelines, tips or recommendations are considered general knowledge and we strongly encourage you to consult with a professional before installing, adjusting, or altering a car audio system.
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.
AGM batteries differ from flooded lead acid batteries in that the electrolyte is held in the glass mats, as opposed to freely flooding the plates. Very thin glass fibers are woven into a mat to increase the surface area enough to hold a sufficient amount of electrolyte on the cells for their lifetime. The fibers that compose the fine glass mat do not absorb and are not affected by the acidic electrolyte. These mats are wrung out 2–5% after being soaked in acids just prior to finish manufacturing.
The plates in an AGM battery may be of any shape. Some are flat, whereas others are bent or rolled. Both deep cycle and starting type of AGM batteries, are built into a rectangular case according to Battery Council International (BCI) battery code specifications.
AGM batteries present better self discharging characteristics than conventional batteries within a wide range of temperatures.
As with lead acid batteries, in order to maximize the life of an AGM battery, it is important to follow the manufacturers charging specifications and the use of a voltage regulated charger is recommended. There is a direct correlation between the depth of discharge (DOD) and the cycle life of the battery, with differences between 500 and 1300 cycles depending on depth of discharge.
