You will need to install an in-line fuse or circuit breaker in the power wire within 18” of the battery. This fuse or circuit breaker protects your vehicle from fire in case the power wire shorts to the vehicle body. If you are only using one amplifier, use the recommended fuse rating. If you are using more than one amplifier, add up the fuse ratings for all amplifiers, and use this sum for your main fuse or circuit breaker. Use a power distribution block or fuse near your amplifiers with the appropriate fuse for each individual power wire.

The information below is a basic formula you can use to determine current draw. A 50% amplifier efficiency rating is used as an average. This formula is only a guideline. Using wire of a larger gauge can only improve the current transfer of your system.

Do not use smaller gauge wire.

Total 4-Ohm rated RMS output x 2 = Total Input Wattage

Total Input Wattage/Supply Voltage = Current Draw (in Amps)

Example: Your MA4100 has 4 channels at 100 watts per channel RMS into

4-Ohms (4 x 100 = 400). You would use the formula below:

400W x 2 = 800W/12.5V = 64 Amps Total Current Draw
