#1 BOSS Audio Systems PV3700 – The Best Budget Car Amplifier

BOSS Audio Systems PV3700 – The Best Budget Car AmplifierWe have a WINNER!

This budget amplifier keeps on giving. It not only has 5 channels to power speakers and a subwoofer but it is perfect for all types of music.

Best of all, it works with a stock system, so there’s no need for additional drilling and what not you will be able to keep the OEM look.

This Boss amplifier is class A/B. So it might go a bit warm, and if you live in a hotter climate, you will need a cooling system for it.

Power Specs:

  • 550 Watts max power output x 4 at 2-Ohms
  • 275 Watts max power output x 4 at 4-Ohms

This is one powerful baby. Besides the standard systems, you can power two 12″ subs or even two 15″ ones. Because it’s a Class A/B, you will get the cleanest, highest quality music. This means there are no distortions even on higher levels.

Yes, this will be super loud; I didn’t go over 30% because it was too much for me.

Have you seen the glass and mirrors dancing to the music? This Boss will give the rhythm.

This is why it’s top of my list:

  • It will get stupid loud: This amplifier is just perfect for teens who like to listen to music insanely loud. For the rest of us, we can turn it down a notch
  • Compatible with Stock: The is amp has everything you will need to power the factory settings. Suppose you’re the adventurous type, then you can power two 12″ and even two 15″ subs.
  • Perfect for Those with Limited Resources: This 5 channel amp is just perfect for anyone who wants to have a rocking system on a shoestring budget

A few drawbacks to consider:

Since it’s a Class A/B amplifier, it will heat up during medium and heavy use. Make sure you have adequate space for ventilation, and also, maybe a few cooling fans won’t hurt.

The lighting is all cool, and it might be distracting during evening driving. So it’s a good idea to put some black insulation tape over it if it becomes a bother.

If you want to power your whole system without spending thousands on a brand new one, this amplifier will do the job nicely. You will be getting a ton of power that creates clean, crisp, distortion-free music.

The cats are out of the bag. Many people have heard about this amazing amplifier, so the rush is on. The supply is going down as the day goes by. You need to step on it if you want this great amplifier at a steal of a price. Grab one while there are still available.

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

  • For teens who like stupid loud systems
  • A monster system that’s worth every penny
  • The perfect solutions for those who have limited resources
  • It’s an overrated amp
  • The bright LED light might bother a few


#2 Alpine MRV-F300 – Best Cheap Car Amplifier

Alpine MRV-F300 – Best Cheap Car AmplifierNot everyone has thousands to spend on luxury amplifiers, and that’s perfectly Ok. This is why I’ve picked this Alpine 4 channel amplifier for you. This is perfect to power 2-6 speakers, and also, you can throw a subwoofer in the mix as well.

It’s also a Class D amplifier, so you know it’s small and efficient. The sound output is simply amazing for the price. The music is clean and crisp without distortions or clipping. Can you ask for more?

Power Specs:

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

This amp rocks on low volumes; you can feel the bass kicking. Let me assure you that you won’t be disappointed because we’re talking about Alpine. They are known to over-deliver. If you prefer SQ, then this is the winner for you.

Best of all, it’s half the price of a JL Audio amplifier. This Alpine sounds fantastic with no hum or distortion.

Here’s why it’s a must-buy:

  • Awesome Buy for the Money: This amplifier is a real champion. Especially it shines with the mids and highs
  • Quality and Performance: The sound that is put out is clean and crisp. I didn’t feel any distortion what so ever even no the highest settings
  • Built to Last: One of my earlier installs is more than 4 years old, and that system is still kicking and thumping as if it would be day 1

Here are a few drawbacks:

Why on earth would someone put mounting brackets out of plastic? Well, this is what Alpine did. I hope these things last.

For a faster and easier install, Alpine should change these screw terminals into fork ones.

All in all, this Alpine is the best cheap car amplifier without compromises. I mean, you’re getting a bunch of power and clean output without bleeding your wallet dry. It’s true that it has a few flaws, and these are not that bad.

Someone let the cat out of the bag, and now everybody is buying this particular amplifier. This means you need to move fast if you still want it. Since the stocks are low, there are no guarantees. You can always check back later to see if they are available.

  • 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


#3 Alpine S-A60M S-Series – Best Budget Car Amp

Alpine S-A60M S-Series – Best Budget Car AmpThis Alpine amplifier is the best budget ever made. Let me share with you why you’re getting the best deal of an unbeatable system.

First of all, this amp is underrated. This means that you will be getting more power than you have paid for. This extra power boost is free. Secondly, it will make your 8″ sub sound harder and harsher. If you happen to have a 12″ subwoofer, then it will sound like there were two 12″ ones. Talk about bang for your buck.

This monoblock amplifier is a Class D, which means you’re getting the most efficient amp class ever. Plus, it has a small footprint, so you can install it anywhere.

Power Specs:

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

After installing this monster, you have a choice to make. You can set it to deliver the best sound quality you have ever heard, or you can set it to massage your internal organs. The choice is yours.

There’s a lot of power hidden in this small package. It’s small enough to hide it under the seat, so it won’t take up valuable cargo space.

Here’s why it’s a must-buy:

  • The Output Will Blow You Away: Let me share with you a secret, by getting this amp, your 8″ sub might sound as if it were a 10″ or even a 12″ one
  • For the Highs and Mids: Simply amazing what this amplifier can do in this range. Plus, you’re getting more juice than advertised
  • It’s Loud: I couldn’t go over 25% because it was just too loud for me. Either way, the neighbours were hearing me pulling up down the street

Here are a few drawbacks:

I hate it when well-known brands cheap out on certain things. This is the main issue with this Alpine amp that there’s no bass knob included. The fact is that you have to buy it separately.

Even if this is a budget car amp, it would’ve been nice if they had a subsonic filter. That can make a big difference.

All in all, this Alpine is the best budget car amp you can go with. It’s a monoblock, so it’s ideal for a subwoofer; however, you can power some speakers as well. It has everything you will ever need to get great SQ. The drawbacks aren’t that bad either.

Since this Alpine amplifier is super affordable, people are buying them up, so no wonder the stocks are at a record low. If you move fast, you might just get one before it’s too late.

  • 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


Buyer’s Guide for Budget Amplifiers:

The old saying that what you get is what you have paid for rings true, and it doesn’t have to be the case. There are more than enough amplifiers for people on the budget, which are not lemons or duds. The list above proves the case.

There are plenty of hidden gems on the market that deliver amazing power to money ratio without the fear of frying.

Besides finding a great and trusted brand or picking an amplifier from the list above, you need to match the amp with your system.

These are the numbers that are the most important ones to check. The first is the power rating, and the second one is the impedance. If you get this right, you will have a great system.

Amplifier Power Rating:

Warning! This number is not the highest one that’s advertised. The highest number is the max power output which is typically inflated to grab attention. In most cases, the amp will never reach that. The real number you should be looking at is the RMS value. The RMS and all power ratings are measured in watts.

What you need to do is look at the power requirements of your system, and now you know that you have to look at the RMS value and find a matching amp for it.

Here’s the good news that RMS value doesn’t have to be on the dot. If you’re in the 70-100% range, that will be perfect as well if you happen to have more power that’s not a biggie because later on you can upgrade or the speakers will handle it.

The problem comes when you don’t have enough power and you risk destroying your system.

Amplifier Impedance:

This is the second most important number and this is measured in ohms. Good thing to keep in mind that the higher the number the harder the amp has to work and less power is produced. The most common impedances are 1,2,4,8 ohms.

What you need to do is look at your system and find a matching impedance amp for it. This has to be a match or things won’t work.

Amplifier Classes:

There are two important classes in the amplifier world. There’s the Class A/B and the Class D. Both have big advantages and both have a few drawbacks.

Class A/B is an older technology that shines by delivering the absolute best sound quality. However it’s not that efficient and makes a lot of heat. This means you will need cooling fans to keep it operational. Also it’s larger than its counterpart.

Class D on the other hand is super-efficient reaching 95% easily which means it doesn’t produce much heat plus it’s small. This gives you multiple options where you can install it. However, the drawback is that the sound is not that clean. Although with recent advances it’s getting there.

Typically Class A/B is used for speakers and Class D for subwoofers to get the best out. Now there are other classes and hybrid systems as well.

Put this newfound knowledge to good use.
