Best Amp for Tweeters with Pros, Cons & Recommendations


Welcome to the Amp for Tweeters Award Show!

After spending the last 15 days in my garage tinkering, installing amps, soldering, heat shrinking, fine-tuning, and driving around while skipping on my favorite TV series (which was heartlessly spoiled by my wife, don’t you worry, missy, we will get even…) I’m ready to reveal which are the very best amplifiers for tweeters.


Finding the perfect amps for tweeters comes down to two things, your current system, and your budget. As soon as you know these, it will be super easy to find the right fit.

There are 20+ years of experience under my belt. I’ve been installing car audio for more than two decades, and I love every minute of it. This is why I’ve decided to share my knowledge to help you cut down research time and find that perfect amplifier.

I’m ranking the top 3 best amplifiers for tweeters on ease of install, their actual power, clarity, accuracy, and value for the price.

No matter which amplifier you choose, you have a guaranteed winner by your side. I have personally vetted them and tested them, so there are no lemons here. You can rest assured that these are good ones.

Let me see those amps already!



#1 Rockford Fosgate P400X4 Punch – The Best Amp for Tweeters Overall

We have a WINNER!

WOW! Listen to that pitch-perfect music. This was my initial impression when I’d started my system up. This 4 channel amplifier does a great job of powering my 4 tweeters.

Brace yourself because this will get loud. In most cases, I had to turn it down because my ears were ringing. The best way to describe this amp after unboxing is that it’s a little tank. Oh boy, oh boy, it delivers.

Here’s what you’ll find under the hood.

Power Specs:

  • 50 Watts x 4 @ 4-Ohm
  • 100 Watts x 4 @ 2-Ohm
  • 200 Watts x 2 @ 4-Ohm Bridged

Let me share with you a secret. You will be getting more power than listed above because this amp is underrated. So you’re getting great value for the money.

People highly recommend this amplifier because it produces clean, crisp music that’s loud.

This is why it’s top of my list:

  • A Good Reason to Get Arrested: If the tweeters would bleed, then you would be charged with assault with battery. It really pushes the tweeters to the limit
  • It’s a Beast of an Amp: The power hidden under the hood will be more than enough to run any system or any configuration
  • Excellent SQ: Music will be on the whole another level. The SQ is out of this world, and you will enjoy clean, crisp sound like never before

A few drawbacks to consider:

Well, it’s not a big deal if you’re using this amplifier to power only tweeters. If you plan to power a subwoofer as well, then this will be a minor issue. Since it’s a heavy amplifier, you most likely will install it under the seat. This will limit your access to the bass boost.

Rockford kinda dropped the ball with the manual. I mean, for a beginner, it will be nearly impossible to configure the equalizer following the manual alone.

All in all, this Rockford Fosgate subwoofer will do an excellent job powering your tweeters. Yes, it has a few flaws which can be easily forgotten when the system is powered up. The tweeters will deliver the best highs you have ever heard.

I have some bad news. Since this amp is so popular, people are buying it up as if it was toilet paper before the pandemic. There’s a real shortage of these amps. There are still a few units available, and if you move fast, you might just get the last one. There’s no time to waste; get one now.

If you want something cheaper, then check out #2 on my list.


Underrated, you’re getting a lot more power for the price

It puts the speakers on notice and cranks every performance out of them

Every music genre will sound amazing


Getting access to the bass boost is difficult

EQ instructions are weak


#2 MTX Audio THUNDER75.4 – Best Value Amp for Tweeters

Talk about value when it comes to an MTX amplifier.

You will be getting the best amplifier for your tweeters, period. Since this amp shines in the highs, tweeters are the right choice for it. The sound quality is loud and clean. I’m ashamed to admit it, but I couldn’t go over 30% of the volume because I was afraid that it would make my ears bleed.

What you’re getting with this MTX unit is a 4 channel amplifier, and it’s a Class A/B. Here’s what’s under the hood.

Power Specs:

  • 75W x 4 Channels at 4 Ohms
  • 100W x 4 Channels at 2 Ohms
  • 175W x 2 Channels Bridged 4 Ohms

Sound enthusiasts swear by it. The music is crisp and clean and very, very loud. There are no distortions, only a clean melody.

Here’s why it’s a must-buy:

  • Party Ghetto Blaster: Holly smokes the amount of power in this baby. Once you pull up at the party and let this monster lose, you will become the center of attention
  • Concert on Wheels: Once you have your system up and running, the music will be like an authentic concert. Maybe it’s time to charge for the lifts?
  • Perfect for Tweeters: This amp produces the very best highs possible, so it’s well suited for tweeters, and it has 4 channels so you can power your entire system with it

Here are a few drawbacks:

This is a class A/B amplifier, so it will be bigger than its class D cousin. So you will have fewer installation options. Plus, it’s not that efficient. Even though it delivers the very best sound quality possible, it produces a lot of heat, so you might need a cooling fan or two.

Also, MTX might’ve messed up the filters on the rear channels. There are two numbers, 50 and 750, so it will be a shot in the dark if you want to get the right amount.

All in all, this MTX amplifier offers a lot of value for the money. If you want to power your tweeters, this will be an excellent choice. Yes, there are a few issues, and it’s nothing compared to all the perks you’re getting.

The cat’s out of the bag people know about this secret gem of an amp. So brace yourself because the stocks are depleting as we speak. The only thing to do is buy it right now, or you risk waiting weeks on end for the next shipment.


An affordable, powerful Thumper system

Great for bragging rights

The perfect amp if you value distortion, static, hiss free music


It’s a Class A/B amp, so you will need cooling fans in hot areas

The blue LED light might be distracting for some


#3 Alpine MRV-F300 – Best Affordable Amp for Tweeters

Wow, this amp really shines in the highs; no wonder that it’s the perfect fit for tweeters. It sounds fantastic, and you won’t be disappointed.

It’s a powerful amplifier and cost less than JL with similar specs.

This Alpine amplifier is a 4 channel Class D amp that is suited for tweeters. Here’s what’s under the hood.

Power Specs:

Besides all these features and benefits, it’s a keeper. One of my earliest installs has been running for more than 4 years, and it’s as clean and clear as if it were day 1.

  • 75 Watts RMS X 4 at 2 Ohms
  • 50 Watts RMS X 4 at 4 Ohms

I loved testing this amp out because it handled like a champ. There are no distortions or clipping, only high-quality music output.

This amp is a silent one and perfectly fits under the car seat. It’s top of the line.

Here’s why it’s a must-buy:

  • Super-Affordable: This is a high quality and lots of power amplifier to power up your tweeters. You can’t go wrong with it.
  • Just what the System Needs: This amp shines in the highs, so it’s the best fit for tweeters. It’s more SQ than SPL, and even so, it’s a keeper
  • Amazingly Clean: Even if this is a Class D amplifier the there’s no static, hiss, hum, or any type of distraction. There’s only clean sound

Here are a few drawbacks:

It seems that Alpine has cut some corners with this amplifier; otherwise, I can’t explain why on earth they would be using plastic mounting tabs. I bet they are saving a few cents with it. Also, I hope these last.

The installation isn’t that streamlined and straightforward. If they would’ve used fork terminals instead of screw terminals, things would be a lot simpler.

All in all, this Alpine amplifier offers a lot of value. If you’re willing to look past its shortcomings, you will have an amazing sounding system. Best of all, you’re getting a ton of bang for your buck.

Since this is an affordable unit, people spread the word about it. Now it’s almost extinct because people are buying it up as if it would be the end of the world. The last time I’ve checked, there were still a few units left. This means if you move fast and buy it now, you might just get the last one before they run out.


Like a champ in its prime, no distortions or clipping

The perfect amp for the mids and highs

Exactly what your system needs for clean, crisp music


The mounting tabs are plastic

Fork terminals would’ve been a better option

What do I hook my tweeters to?

You hook the tweeters to your car’s stereo crossover. All this after you have placed the tweeter inside the base cup. It’s quite simple.

Do I need crossover for tweeters?
