# What size amp do I need for a 1200W sub?

## What size amp do I need for a 1200W 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 I need to push 2 12s?**

Then determine the amount of power your subwoofers can handle. RMS power handling of a 55 series 12” dual 2 ohm voice coil subwoofer is 400 watts. Two of these subwoofers would mean you need 800 watts of power at to the total circuit impedance.

**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 know what amp to get for car speakers?

For your speakers, use an amplifier whose top RMS output per channel is no higher than each speaker’s top RMS rating. For your amplifier, get speakers with top RMS ratings that are equal to or higher than each amp channel’s top RMS output.

**Can a mono amp power 2 subs?**

The 2 outputs of a mono block amplifier are there to easily connect multiple subwoofers. If you are not sure whether your amp is a mono block or a multi-channel model, look at the speaker terminals.

**Can a 1000 watt amp push 2 15s?**

Just make sure your 15″ subs have a rms rating of 1000 watts…. because under powering your subs is worse than overpowering them. And GUH. see less Yes, it will push two 15’s easily.

#### How many channel amp do I need?

In general, you need one channel for each speaker that you want to amplify. If you’re adding a subwoofer to an existing system, then a single channel amplifier will get the job done.

**How do I match my speakers to my 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.

**Can you use a 4 channel amp for 1 sub?**

You can’t unless you have a dual voice coil sub and put each coil per 2 channels bridged which I don’t recommend because the gain setting has to be exact. You can bridge 2 channels together for that one sub but you have to see what impedance your sub is at.

## Can you wire 2 subs to a 1 channel amp?

This setup is perfect for a mono sub amp. By wiring the two subs in parallel (see the diagram) you’ll show a 2-ohm impedance to the amp. Mono amps are built for just this kind of situation, so you’ll get maximum power output from your amp investment. Two 4-ohm SVC subs — a great place to use a mono amp.

**Are Class D amps good for subs?**

The very best amplifier for a subwoofer is a class AB or Class H amplifier. Class D amplifiers are too slow and cannot keep up with repetitive bass. Buy the power amp that matches the subwoofer.

**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.”

### What size subs do I need for a 500 watt amp?

Let’s say you choose to maximize the amp’s potential and want the system to put out 500 watts RMS. This means your subs have to be wired to form a total impedance of 2 ohms. Two subs on a 500 watts RMS amp will want about 250 watts RMS each. So you’ll look for subs each rated for 250 watts RMS or more.

**How do you hook up two subs to a mono amp?**

By wiring the two subs in parallel (see the diagram) you’ll show a 2-ohm impedance to the amp. Mono amps are built for just this kind of situation, so you’ll get maximum power output from your amp investment. Check the diagram below for how to hook it up. Two 4-ohm SVC subs — a great place to use a mono amp.

**How many DVC subs do I need to power 6 amps?**

Justin, Those subs are actually rated for 1600 watts RMS each and come in DVC 1-ohm and DVC 2-ohm models. Twelve of the DVC 1-ohm subs should work well with six amplifiers that could each power a pair of those subs with up to 3200 watts RMS at 1-ohm]
