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

The-Best-Amp-for-TweetersWe have a WINNER!

WOW! Listen to that pitch-perfect music. This was my initial impression when I started my system up. This 4-channel amplifier does a great job of powering my four 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, 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 a secret with you. You will be getting more power than listed above because this amp is underrated. In other words, you’re getting great value for the money.

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

Here is why it’s top of my list:

  • A Good Reason to Get Arrested: If tweeters could bleed, 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 configuration
  • Excellent SQ: Music will be on a whole other 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 at 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.

Finally, 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. But there are still a few units available, so 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, check out #2 on my list.

  • Underrated, you’re getting a lot more power than expected for the price
  • It puts the speakers on notice and cranks every performance out of them
  • Every music genre will sound amazing
  • Accessing the bass boost is difficult
  • EQ instructions are weak


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

Best-Value-Amp-for-TweetersTalk 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 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, clean, and very, very loud. There are no distortions, only a clean melody.

Here’s why it’s a must-buy:

  • Party Ghetto Blaster: Holy smokes, the amount of power in this baby! Once you pull up at a 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 four 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. Thus, 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, it will be an excellent choice. Yes, there are a few issues, but 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’ll risk waiting weeks on end for the next shipment.

  • An affordable, powerful Thumper system
  • Great for bragging rights and to show off your great system
  • 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 it’s the perfect fit for tweeters. It sounds fantastic, and you won’t be disappointed.

It’s a powerful amplifier that costs 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 installations 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 out this amp 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 high quality and it features lots of power amplifiers 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, 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 it is an affordable unit, people spread the word about it. Now, it’s almost extinct because people are buying it up as if it were the end of the world. The last time I 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
