6 Frequently Asked Questions about “Battery installed in the amplifier”

What size battery for car audio?

The size of the second battery for car audio depends on how much power your amplifiers need. As a general rule, you need a 100Ah battery for every 1,000 watts RMS of your car audio. The table below shows a few examples of popular batteries with the RMS wattage that can support on top of standard electronics in the car.

Can you add a second battery to a car audio system?

If you are adding a second battery, do not use old terminals from the acid lead battery, but install clamps with multi-connection points instead. Power and ground wires used for a second battery should have the same gauge as the other power wires used in the car audio. Remember never to use ground wire that is smaller (thinner) than the power wire.

Where should car audio batteries be placed?

Additional car audio batteries should be placed close to the amplifier, and the most common places are either inside the cabin or in the trunk. Batteries installed inside the car should be leak-proof and vibrations resistant, and this is another reason why you should not use standard lead-acid batteries for car sound systems.

Where should I Mount my amp?

Mount your amplifier in the location you've chosen. The power wire from your amp wiring kit (usually 16-20 feet in length) needs to run from the battery, through your car's firewall, through the car's body to the amp.

How do you install a car amplifier?

Start by finding a flat spot inside your vehicle and screwing your amplifier down to mount it. Run the wires from an amp installation kit along the sides of your vehicle so you can connect them to power and the stereo system.

How to wire an extra car audio battery?

How to wire an extra car audio battery depends on the type of battery used and if it is the same battery type as your primary or a different one. The simplest way to connect a second battery is when it is the same type as the primary one and is placed, for example, in the trunk.
