# Question: What size capacitor do I need for a 1500 watt amp?

Contents

But for a 1500 watt RMS amp you should be good with a 2 or 2.5 farad cap.

## What size capacitor do I need for my amplifier?

The rule of thumb is to put in 1 Farad of capacitance for each watt of power. Many see benefits with 2 or 3 Farads per 1,000 watt RMS, and there is no electronic penalty for using larger value caps. The bigger the cap, the quicker it gets ready for the next hit.

## What size capacitor do I need for a 1000 watt amp?

A: The rule of thumb is to put in 1 Farad of capacitance for every 1,000 watts RMS of total system power. But there is no electronic penalty for using larger value caps, and in fact, many see benefits with 2 or 3 Farads per 1,000 watts RMS. The larger the cap, the more charge is available for the amp when it needs it.

## How many watts can a 5 Farad capacitor handle?

SoundBox SCAP5D, 5 Farad Digital Capacitor for Car Audio - 5000 Watts.

## Can a car audio capacitor be too big?

It really doesnt matter how big the capacitor is. In fact, a bigger capacitor can lead to bigger problems. Bigger capacitors have longer charging times. This means that they will draw more current from your alternator for longer periods of time.

## How do I know what size capacitor I need?

Multiply the full load amps by 2,650. Divide this number by the supply voltage. The full load amps and the supply voltage can be found in the owners manual. The resulting number is the MicroFarad of the capacitor you need.

## How do I choose a capacitor?

The capacitor physical size is directly proportional to the voltage rating in most cases. For instance, in the sample circuit above, the maximum level of the voltage across the capacitor is the peak level of the 120Vrms that is around 170V (1.41 X 120V). So, the capacitor voltage rating should be 226.67V (170/0.75).

## What is better capacitor or battery?

Batteries are high-density potential energy stores. Compared to caps, batteries require less space to offer the same amount of energy. Car batteries solve more serious electrical issues since they can provide energy for longer periods than capacitors.
