Best Car Amplifier 2018

Rockford Fosgate Punch P500X2 2-Channel Amp

Best Car Amplifier

Amps, they power your subs and speakers. The speakers can take so many watts, and your amplifier cannot put out more watts than that. If you’re just an everyday consumer looking for good sound and know little or nothing about car audio electronics, I will show you how to buy the best car amplifier for your situation.

You can go right to what type of amp you’re looking for
2-Channel Amplifiers
Mono Amplifiers
Multi-Channel Amplifiers – Good for everyday people who want a good sounding system like they do at home.

You need to know or find out, how many watts your speakers can take. Speakers have an RMS rating, or what is the manufacturer’s suggested watts. If your speakers are rated at 100 watts, then your amp cannot exceed that. That doesn’t mean you need an amplifier that’s a 100 watts to each speaker, you could have an amp that’s only 50 watts x 2(each speaker getting 50 watts), and you will get amazing loud sound quality still. They same goes for subwoofers and speakers. Do not concern yourself with peak ratings of either, like a sub has an RMS rating of 300 watts and a peak rating of 600 watts like all speakers do. Just buy your amps, subs, and speakers around the RMS rating and don’t exceed that. I was a professional car audio installer for many years, I know what I’m doing.

Amplifiers are rated at different impedences(ohms). 4 ohms being the normal rating everyday consumers should be concerned with, and yes it does honestly matter this isn’t like home audio and you just wire the speakers. Most car speakers are 4 ohms, subs, come either 2 or 4 ohm and you would buy them accordingly like from Amazon. There are many ways to wire amplifiers and speakers so you would have a 2 ohm load or up to 8 ohms. It’s not of any importance to most of you, but the speakers then get a different amount of watts at different impedences. So the average consumer will just be concerned with 4 ohms, unless you have an amplifier that’s bridgeable and rated at like 500 watts at 2 ohms. In that case if you don’t know how to wire your speakers or amps, look it up online or call your local car stereo place and they will help you.

If an amplifier is rated at 100 Watts x 2 at 4 ohms and 200 Watts x 1(mono) at 2 ohms, you can either use it for two 6.5″ speakers that will both get 100 watts, or use it mono to one or two subwoofers. It then gets both channels power to make it 200 watts. My example amp is rated 2 ohms mono, if you wire two 4 ohm subs in parallel, 4 divided by 2 = 2 ohms. Now you have a 2 ohm load and each woofer will get 200 watts. I’m not gonna get into how to wire speakers and subs in series or parallel, you’ll have to learn from searching on the internet, read here, or have a local professional help you.
