asked in category: General Last Updated: 21st June, 2020# What amp do I need for my sub?

**need**a total of 700 watts RMS. The last is too high a load to be practical, so you'll look for an

**amp**that can put out up to 700 watts RMS into either a 4-ohm load, or a 1-ohm impedance load: up to 700 watts RMS x 1 at 4 ohms, or. up to 700 watts RMS x 1 at 1 ohm.

Subsequently, one may also ask, do I need an amp for my sub?

The short answer is that everyone who wants a **subwoofer** in their car also needs a **subwoofer amplifier**. As to whether you **need** a separate **amp** for your **subwoofer**, that depends on the hardware you already have and the car audio system that you're trying to build.

Subsequently, question is, how many watts do you need for a subwoofer? 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. A system with 100 **watts** RMS per channel — having at least 1,000 **watts** RMS, or more for the **sub** is not uncommon.

In this manner, what kind of amplifier do I need?

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 hits harder 2ohm or 4ohm?

The **2**-**ohm** Subwoofers Hence, the **two ohms** subwoofers are louder than the **4 ohms** subwoofers. However, the **2 ohms** subwoofers may be louder than the subwoofers with more higher resistance; it is may also produce a low quality of sound because of its power consumption.
