Best Monoblock Amplifier with Pros, Cons & Recommendations


Welcome to the Best Monoblock Amplifier Award Show!

After spending the last 14 days in semi-isolation installing amplifiers, heat shrinking, soldering, running wires and fine-tuning meanwhile skipping on house chores and on kid’s bedtime stories (sorry honey…), I’m ready to reveal the best monoblock amps on the market today.


Finding the perfect monoblock amp comes down to three things, your power needs, available size and your budget. As soon as you know these, it will become super easy to find the perfect fit.

For more than 20 years now, I’ve been tinkering in the car audio world. I’ve installed so many audio-related items that I should’ve gotten a degree already. Now I know how hard it is to find the perfect amplifier, and it takes so much time. This is why I’ve decided that I will help you with my knowledge, so the choice is fast and easy.

I’m ranking these 5 monoblock amplifiers on looks, ease of install, how hard they punch and, of course, power-to-cost ratio. Also, you can rest assured that picking any amplifier from the list above is a guaranteed winner. You can’t go wrong with it.

Let me see those amps already!




#1 Kicker 46CXA8001 – The Best Monoblock Amplifier Overall

We have a WINNER!

This Kicker amplifier is the best of the best. I loved this amp so much because it delivers a tight bass, plus it punches a lot harder. I mean, if you have a trunk, this will shake it to the frame.

I have tested multiple configurations, and while playing, a 10” subwoofer neighbor walked by and didn’t want to believe that it’s just a 10” sub in the back. Your subs will work overtime when they are matched up with this amplifier.

Power Specs:

  • 1600 Watts Peak Power output  (max power output)
  • 600 Watts RMS at 2 omhs (rms power handling)
  • 800 Watts RMS at 8 ohms (rms power handling)

What I love about this amp is that you will have more than enough bump in the car without disturbing the peace. You will be able to feel the bass inside, and the outside will be quiet. Since I brought it up, the installation has been quite simple.

I can’t get enough with this bass performance. It’s deep and hard, just as I like it.

This Kicker amplifier is a small unit, so you will have multiple install options.

This is why it’s top of my list:

  • A True Vehicle Shaker: Man, oh man, this is brutal the amount of power it puts out. No matter what kind of the previous system you had, this amp will make a night and day difference
  • Those Poor Subs: I feel for those unsuspecting subs you have. There’s no other way to put it than saying the subs will get a regular beating when you plug it into this amp
  • Versatile Configuration: While this amplifier is perfect for a single sub setup, it’s not your average amp because you can easily power two 10” or even two 12”

A few drawbacks to consider:

A few people mentioned that this amplifier shuts down when it gets hot. The best way to prevent it is if you have 6” of space for adequate ventilation.

Well, this rubs me the wrong way. The bass remote is an added expanse. You have to buy it separately. Come on, Kicker, you can do better than this.

Besides these minor inconveniences, this amp delivers. So if you want something that’s made by a well-known brand and you want some good bass, this is the Winner!

I hate to say this, and you have to move because these amplifiers are popular, and people are buying them up like crazy so if you don’t want to wait weeks for the next supply, grab one before it’s too late.

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

  • Tight and Deep bass that hits harder than you can imagine
  • Over-deliver since you can power two 10” or two 12” subwoofers
  • Sounds amazing, excellent quality in a compact package
  • If it overheats, it will shut down
  • The bass knob has to be purchased separately


#2 Taramp’s Smart 3 – Best Class D Monoblock Amp

This Taramp’s amplifier is on its league of its own. I mean, there are some JL and Rockford Fosgate amplifiers out there, and you need a second mortgage compared to this one. It’s simply a steal of a deal.

Warning! Don’t even think about letting this monster loose if you have some cheap subs. Even the best of the best subs are tortured by the power what this amplifier delivers.

When I’ve first started up, I thought the sub would jump out from the box. I’m worried that after extended use, the door panels might actually fall off. Most likely, it will flex your car. I’ve even managed to vibrate my windshield vipers.

Power Specs:

  • 1 OHM: 3000 Watts RMS power handling
  • 2 OHMS: 3000 Watt RMS power handling
  • 4 OHMS: 2000 Watts RMS power handling

My initial reaction was that this small Class D monoblock amp would not deliver 3000 watts. Think again! I was shocked to see that it’s not overrated. It really puts out 3000 watts.

This amplifier comes with a clipping indicator which is a welcome sight, and it delivers great sound quality.

Here’s why it’s a must-buy:

  • Beware it’s a Little Monster: Don’t underestimate this amplifier by its looks. This bad boy delivers insane power
  • It Makes the Subs Shine: I feel for those subs; they are pushed to their limits. Yes, the bass is stronger than ever before
  • Bang for Your Buck: Wow, simply just WOW. I can’t believe you can get such quality and insane power at a small price like this. I believe they made a mistake pricing it this low

Here are a few drawbacks:

You need a serious equipment upgrade to actually get those 3000 Watts. A second battery is a must and at least 150A alternator because it takes power to make power.

It doesn’t come with a low pass filter. It would’ve been nice, though.

All in all, this Taramp’s Amplifier is a rare gem. Not only is it a Class D monoblock amp, but it’s one of the best. It’s small efficient and delivers more juice than you will ever need.

Maybe it’s a mistake that they have priced it this low, or it’s temporary; either way, grab one while you still can. People are buying it up like hotcakes. Get one right now.

  • A small monster that delivers insane power
  • My subs never sounded this good
  • It’s a steal of a deal, and you can’t get anything better at this price range
  • Serious investment needed for the electrical system
  • There’s no low pass filter included


#3 Alpine S-A60M S-Series – Best Mono Amplifier For Car

This Alpine amplifier is underrated. You’re getting more juice than advertised. Also, make sure you don’t pass judgment on its size because it packs a punch.

How I see it is that this amp can be configured to get great sound quality or to rattle your internal organs. This comes down to your own preference.

Since the size is small, you can practically mount it anywhere. In most cases, under the seat is a perfect position. Also, it’s a Class D amplifier, so it won’t get hot no matter what.

Power Specs:

  • 330 watts RMS power output x 1 at 4 ohms
  • 600 watts RMS power output x 1 at 2 ohms

What I like about serious amplifier brands is that they come with a certification. In most cases, the certification shows more power than advertised. This means that you’re getting some extra juice without spending a dime.

As a matter of fact, the Alpine S-A60M is an investment in the best sound you will ever hear.

Here’s why it’s a must-buy:

  • Power in a Small Package: It’s insane how hard this little guy hits. I mean, the subs are way more powerful than they used to be
  • Better Performace without a Serious Investment: If you have an 8” sub, it will sound like a 10” or a 12” one. If you have a 12” woofer, it will sound like two 12”
  • A True Gem: With his amplifier cranking out the juice, people will hear you coming down the street

Here are a few drawbacks:

There’s no bass knob included. I mean, we’re talking about Alpine, not some cheapo brand. Alpine, you can do better than this.

Also, I miss the subsonic filter that’s a must-have in my book.

All in all, this amplifier is a masterpiece. It’s perfect for the highs and mids, and it makes all subs sound like they are bigger or better.

So no wonder why they are so few left in stock. People love Alpine and want to get the best amplifier for their car. This means that you have to move fast if you want to feel some bump. Grab one now or else wait for weeks.

  • It’s a tiny looking amp, and it delivers a hell of a punch
  • It will make your sub sound harder and more expensive
  • It’s the perfect choice for the highs and the mids a true gem
  • The bass knob costs extra
  • There’s no subsonic filter


#4 Planet Audio PL3000.1D – Best Monoblock Amp For The Money

Here’s my shameful admission. I was highly sceptical about this amplifier, and it turned me into a believer when it blew my speaker box.

If you want bragging rights, then this amplifier will deliver it. It’s so easy to shake the other cars at the red light. I only have to turn it down when I have my wife or the kids in the back. Other than that, no mercy!

Power Specs:

  • 3000 Watts Max power handling x 1 at 1-Ohm
  • 1500 Watts Max power handling x 1 at 2-Ohms

This amplifier makes the whole system bump harder as a matter of fact I’ve got to the point to vibrate my vision. I didn’t know that was even possible.

What you’re getting with this amp is crisp bass and the sound is loud and clean. The build quality is good and it seems to be durable. I had no issues whatsoever.

Since it’s a class D amplifier you know that it’s highly efficient and won’t overheat.

Here’s why it’s a must-buy:

  • Your Choice: You can set it to get a decent bass or go overboard and shake the other cars at the stoplight while vibrating your vision
  • Makes Long Drives Pleasurable: This amp delivers great sound with minimal fuss; once you’ve set it up the bass is great and the miles fade away
  • Ultimate Gift: This amplifier is the best gift for those who sound fans who love the feel of premium audio and amazing sound experience

Here are a few drawbacks:

That 3000 Watt output is highly optimistic. They have inflated that number significantly yet it doesn’t mean it won’t deliver.

A few people mentioned that in certain vehicles it’s a real pain to install

All in all this is a very good monoblock amp even though it’s overrated at 3000 Watts it still delivers more than enough juice for the sub. As a matter of fact my sub sounds way better with this amplifier than with a more expensive 5000 Watt one.

As you know this is a popular amplifier so people are buying like crazy. Do yourself a favor and get it right now or you risk waiting for a long time because shipments are slow these days. Get it now.

  • Perfect balance between being enjoyable and pissing people off at the red light
  • There’s only a minimal distortion at the highest level, it’s perfect otherwise
  • It will vibrate the mirrors and rattle the trunk
  • Overrated at 3000 Watts
  • Installation difficulties with certain vehicles

#5 BOSS Audio Systems R1100M Riot Series – Best Car Monoblock Amplifier

Boss has really outdone itself with this amplifier. I mean just look at it. This is one cool amp that delivers the power needed for a great bumping system.

I love how the logo lights up in red. It’s a real shame if you have to hide it under the seat. It’s a sexy amplifier.

In short this Boss amplifier thumps, bumps, booms, and pounds.

Power Specs:

  • 1100 Watts max power output x 1 at 2 Ohms
  • 550 Watt max power output x 1 at 4 Ohms

Warning! You might need to get two of these amps and it’s not what you think. While I was testing this amplifier my wife heard it and wanted one as well. Luckily the price is insanely low. And this is compared with a 6-year platinum warranty. It’s not a throwaway amplifier.

You can hate me as much as you like and I’m saying that this amplifier is as good as an expensive Kicker amplifier. It’s not for competition yet it will make your drive pleasurable.

Here’s why it’s a must-buy:

  • Heavy Duty Amplifier: To all the skeptics out there I have friends who are pushing it hard every day for months and years and it’s performing like it would be its first day
  • Great Bump: The reason why I love this amplifier is because it bumps the car without disturbing the peace
  • Bang for Your Buck: The price is a real steal. Damn, it’s insane how much power you’re getting at this price. Even though it’s overrated it’s worth it

Here are a few drawbacks:

A few people mentioned that this amplifier tends to overheat especially if there’s a carpet. The simplest solution would be adding spacers because the vents are facing downwards.

There were also complaints that the remote is not working. Well, there’s a trick to it you have to turn it up to max then you can use the remote and adjust it as needed.

All in all this Boss amplifier is a good one. The price makes it almost throw away yet it lasts for a long time and delivers on all fronts.

I hate to say this and here it goes by far it’s the #1 best-selling amp on the market. So you will be lucky if you manage to get one because they are flying off the shelves. Since the price is unbeatable it seems everyone wants one all of a sudden. Grab one before someone else does.

  • Build to last many friends are bumping to it for a long time
  • The bass delivered is nice you can’t go lower in price than this
  • Steal of a deal, you can get some good thumping on the budget
  • Overheating because the vents are facing downwards
  • There’s no subsonic filtering
