Frequently Asked Questions (FAQs)

1. Does a car amplifier power cord need to be connected directly to the battery?

The first three connections are necessary in order to provide power to your car amplifier. The battery power cable should be hooked directly to the positive terminal on your battery, which means that you'll have to route it through your car's firewall at some point.

2. Where does a car amp get power from?

Power source: Unlike home stereos powered by an alternating current (AC) electrical outlet, car amps work from a +12V direct current (DC) supply. You'll need a +12V AC-DC power supply with enough current to run the amp. Not just any AC/DC 12V adapter will do – I'll cover this below.

3. Can you wire an amp directly to the battery?

The best way to ground your car stereo components is to run a 10 or 12-gauge wire from the amp, and 12-gauge from all other components, such as head unit and active crossovers, to a central location. Then run a single ground to the best source of ground, the negative terminal on your car's battery.
