How many amps do I need for my car audio system?

In most cases, you’ll want one amp for all the speakers in the car, which means you’ll need multiple channels on the amp — each channel drives one speaker. Since most cars have four speakers, four-channel amps are the most popular. Five- or six-channel amps will give you even more options.
How many watts do you need for a good car audio amp?
Answer provided by If the stereo you buy is the same as your car’s original factory stereo, you should be looking at 50 to 200 watts RMS of power. If you want to make your listening experience a little easier with an aftermarket receiver, though, you might want closer to 200 to 300 watts RMS.
How many amps is a car speaker?
The average regular car stereo draws from about 2 to 10 amps. If you really turn up the volume, you’re typically in the 8-12 range. However, if you look to upgrade your speakers, you’ll likely be closer to 30 amps! If you upgrade, ensure your battery can handle the additional power.
Can a car amplifier be too powerful for speakers?
Amplifiers can be too powerful for speakers. Speakers are limited by the electrical energy that they can convert into audio. As a general rule, if the amplifier produces more electrical energy than the speakers can handle, it may cause distortion or clipping, but damage is unlikely.

What if my amp is too powerful?
How do I know what amp to get for my speakers?
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.
How do you match speakers to amplifiers?
Speakers typically carry ratings between 4 and 8 ohms. Amplifiers generally operate effectively in a specified range: say, 4 to 16 ohms. Check your specs, but when that’s the case, connecting a speaker rated between 4 and 16 ohms will be OK.
