How do I know what size amp I need for my subs?

Step 1: How much power? Find out the “watts RMS” rating of the sub. Then, multiply the number of subs you have by the RMS rating of each, to get their total RMS rating. You want to make sure the amp you choose will supply no more than the sub system’s total RMS rating.

What amp is needed for a 1200 watt sub?

A 1200W subwoofer will WORK with a 10W amp too, a 50W amp or a 300W amp as well. It just won’t be as loud as you might like it to be !

How many watts do you need for a subwoofer?

If you have: A factory radio — you won’t need more than 50 to 200 watts RMS of power for the bass. An aftermarket receiver — you might want 200 to 300 watts RMS of power. Amplified speakers with around 50 watts RMS per channel — 250 to 500 watts RMS is a good starting point.

How do I choose the right amp?

Generally you should pick an amplifier that can deliver power equal to twice the speaker’s program/continuous power rating. This means that a speaker with a “nominal impedance” of 8 ohms and a program rating of 350 watts will require an amplifier that can produce 700 watts into an 8 ohm load.

What type of amp is best for subwoofer?

How many amps does a subwoofer use?

A decent stereo setup will include subwoofers and a speakers that’ll draw about 5-10 amps.

What is a good RMS for a subwoofer?

Can a 1 channel amp power 2 subs?

You CAN run 2 speakers off of a 1 channel amp, just that amp is way too little power for your subs.

How do I choose the right subwoofer for my amp?

Getting the right sub for an amp, or the right amp for a sub, is like solving a puzzle. A subwoofer has impedance (measured in ohms) which represents the “load” an amplifier will sense on its output. An amplifier will put out different amounts of power (watts RMS) based on the impedance load it “sees.”

How many subwoofers do I need for a 400 watt amplifier?

For example, and amplifier that has 400 watts should be paired with one subwoofer that runs at 400 watts, or two subwoofers that run at 200 watts each. Regardless of the combination, the main goal is to equal out the power while running the products at their respective continuous power ratings.

How do you find the impedance of a 2 subwoofer?

Ideally, Bob want’s 2 x 250 watts = 500 watts for the two subs. From the formula above, we see that we can lower the total impedance of the two sub system if we wire in parallel. So we take the 4 ohm impedance and divide by two subs, which results in 2 ohms total impedance.

How do you calculate the volume of a subwoofer?

To calculate interior volume, first convert all fractions to decimals (½ = .5) before entering the width, height, depth, or diameter, and thickness into any of our speaker box calculators below. For additional subwoofer wiring options, please see our Subwoofer Wiring Wizard.
