Car Amplifiers for Bass Buyer’s Guide
Finding the best car amplifier for bass tones can be a walk in the park if you know what to look for. But if you’re new to the world of car audio systems, you should read our guide below to know what factors you should consider. Otherwise, you might end up with an amp that doesn’t match your vehicle or something that could damage your system.
Power
Power ratings are all about numbers. However, one must know the difference between the peak power output and the RMS of an amp. This way, you won’t be fooled by manufacturers who advertise their products as ‘better’ due to the higher numbers on the specs sheet.
When buying an amp, remember that the max power or the peak power rating equates to the maximum amount of voltage the unit can produce without breaking down. Put simply, it’s the amount of power that an amplifier can handle safely.
On the other hand, the RMS (Root Mean Square) refers to continuous power handling, or how much power an amplifier can produce. The RMS power is typically lower than the max power output, but it actually is a better representation of how much power your amplifier can handle.
To make sure you’re purchasing an amplifier that won’t break down in a few weeks, choose something whose RMS power output per channel is not higher than the top RMS rating of each speaker in your car sound system.
Channels
If you’re only looking to power your subwoofer, a single-channel or monoblock amplifier is all you need. If you’d like to power your front speakers as well, a 3-channel amplifier will be a good option.
However, if that’s the case, we recommend going for a 4-channel amplifier instead. That way, you can configure two channels for the speakers and bridge the other two for the subwoofer. If you decide to have a full-range audio system down the road, then your amp will be ready for the upgrade.
On the other hand, you can also go with a 5-channel option if you want the full package. Each speaker will have its own channel, and the other one will be for the sub.
You can also find 6- or 8-channel models in the market, but expect to pay a premium for these. You’d have more flexibility, though, as you can have a double-bridged sub or have a multiple active system for every car speaker.
Mono vs Multi-Channel Amps
As you may have grasped from the previous section, it’s pretty easy to tell the difference between a mono and a multi-channel car amplifier. The most important thing is for you to decide how many channels you want to have.
Monoblock amplifiers like the Boss Audio R1100M and the Planet Audio AC1500.1M, which are both featured on our list above, are great for powering the subwoofer alone. Installing a mono results in a more powerful bass response.
If you’d like more flexibility in your setup, however, the 4-channel Rockford Fosgate R1200 or the 5-channel Rockford Fosgate Punch P1000X5 would be more suitable. They can provide amplification for your other speakers as well, and if there are extra channels, you can bridge them for an extra kick.
There is one caveat for multi-channel models, though. Because they share the load between speakers, the bass response is slightly compromised. However, they still work well for the bass and you won’t really notice the subtle difference.
Amp Class
When buying a car amplifier, you will often see Class A/B or Class D on the sheet and not know what it means. Each amplifier class is basically a design category that tells us how the electric circuits inside the amp combine power and signal for operation.
Class A is the most basic one. It just has one transistor in a linear mode. They offer great sound fidelity, but it has poor efficiency.
Class B amps use two transistors, and are more efficient than Class A. The drawback, however, is crossover distortion. [1]
Class A/B combines the best things about A and B. They produce great sound, no crossover distortion, and have good efficiency. This class is common in many low-cost options today.
Class D is the go-to type for many people. Its main benefit is its high efficiency of about 90%, which then allows it to be more compact without the addition of cooling systems and heatsinks. A Class D amplifier doesn’t offer the highest sound fidelity, though, but most people are okay with the compromise.
Compatibility
Of course, it’s important to purchase an amplifier that is compatible with the rest of your car audio system. Determine the right power rating, the number of channels, and the size of the amplifier itself. Remember that some amplifiers may be too little or too bulky for your car, so make sure you have the space first.
Our experts also emphasize the importance of matching the amp’s output power to your speakers’ required power. When these don’t match, you will either get weak sound or blow your speakers out.
FAQ
What class amp is best for bass?
Class D is the best class amp for bass. Not only are they highly efficient, they are also equipped with low pass crossover filters that minimize distortion at high volumes.
