What to Consider Before Buying a Class D Amplifier

For the best decision to be made on a class d amplifier, you need access to more information. This information will give you tips, hints, and valuable advice to help you select the amp you’ve always wanted.

Due to the need for more info, I’ve added a complete guide to help you make a better buying decision. Let’s take a look:

The power consumption of the amplifier:

Amplifiers have different rates of using power in your vehicle when operational. You need to take a look at the rate at which your choice amplifier consumes power. Separate ratings can be used to assess this, but the wattage and RMS are the right places to start.

Covering material:

The covering material of most amplifiers today is made from metal. The housing of your amp will determine how long the amp lasts and some other factors. There are amps that come with heat-sink and other protective tech. This tech depends solely on the covering of the amp. If your favored amp doesn’t have a defense against the elements and short-circuits, then you may need to make another choice.

Your sub-woofers power:

In your vehicle, the only way you can enjoy the best sounds through an amp is by adding a sub-woofer set. Apart from having a sub-woofer set, you have to consider if the amp exceeds the woofer too much. If your amp has considerably more power than your sub-woofer, you may be in the market soon for a new set of woofers. It’s also essential to know that a sub-woofer should have more power over an amp than the other way round.

Cover design:

Apart from the material used in making the amp, its design is also worth looking at. The design of an amp can go a long way in tipping the sound produced by your speakers. Also, the cover design could help in protecting your investment with a compact design. When your amp’s cover has a sleek design, it’ll be more difficult for the elements to have a direct impact on its performance.

Protection interface:

When selecting an amp, take time to check the packaging for what protection the circuit board has. Some people overlook this, but it’s a risky thing to leave out when making a decision. Amps today are made with various types of integrated circuit protection tech. Such tech is required for your amp, as you may need to use it for long journeys. When there is no IC protection for your amp, the chances of damage are increased multiple notches.

Peak power:

The peak power of an amplifier will go a long way in satisfying you if you’re an ardent lover of louder music sounds. Endeavour to check the peak power of the amplifier and also the RMS and impedance at which it performs. It will help you to know how you can tune your amp to the best position without causing any damage.

Your budget:

Money is a factor in many things we do in life. It’s equally important to take a look at your pocket when choosing an amp. There are amps that can be classified as being expensive for nothing. In selecting an amp, the price may not be equal to quality, so check out a cheap, high-performance amp if you’re on a budget.

Maintenance Tips for Your Amplifier

Keep the volume at an average level:

It’s surely tempting to floor the volume of your car sound system when a new amp has just been installed. No matter how thrilling it may be, you shouldn’t ever try doing this. If you only had a new amp installed on a vehicle with old speakers/subs, then excess power flowing through your amp can easily damage your appliances.

When you get a new amp installed, the best way to use it is to get a personal check. Turn on the system and determine where the sound volume of your speakers is just enough. It’ll help you protect the amp from damage, and you’ll enjoy the best sounds without any problems.

Place the amplifier on a flat, sturdy surface:

When installing your amp, it may be tempting to chug it off at any corner. It’s not advisable as you could impede the performance of the amp. The recommended spot for mounting your amp is on a horizontal surface, preferably deep inside your trunk area.

Keep your amplifier away from any liquid contact:

This boils down to where your amplifier is set up. If you have the amp set just right in the flooring of your trunk, don’t stack anything on it. If any liquid gets in contact with your amp, then the circuit boards will definitely get fried, and you’d need to spend extra cash in getting a fix or replacement.

Common Mistakes to Avoid

Trying to be a DIY when checking the rating:

We all know how enticing it is to be a DIY-guy every now and then. It may even make you feel powerful sometimes. But when amps are in play, don’t try checking the rating to merge with your sound system yourself.

The best option when trying to tweak the performance of your sound is to get help from a pro. No need to do any stuff yourself when you get such people to measure the power your amp delivers to your speakers.

When you get a technician to check your sound out, you’re also assured that you’ll not need to spend extra cash if you’d damaged anything during your DIY spell.

Poor maintenance culture:

Just like the other parts of your car, the amp also needs some form of regular maintenance. When you abandon your amp under a trunk or seat, it may accumulate dust and other particles that may cause faults to develop in your amp. The safest step is to clean the outer area of your amp with a damp cloth whenever you’re cleaning the interior of your car thoroughly.

Fitting your sound system in absorbent areas:

Your sound system will perform better when the fitting is just right. Speakers are mostly installed in-door panels nowadays. Some of these installations are plain wrong. If your amp is to perform well, your speakers should be installed without any padding or sound-absorbing material in the way. It’s a lousy choice to fit your speaker or subs underneath the seats of your car, as the sound will be absorbed by your car’s floor.

How to Maximize the Performance of Your Class D Amplifier:

Get the right sub-woofers and speakers:

Your subs and speakers can determine how well your amp performs. If you have underperforming, out-of-date sound accessories, then your amp’s effect may be significantly dulled.

What you need to do when hoping to get the most from your amp is to ascertain the performance of your current subs and speakers. If you don’t like how it performs with your new amp, then think about getting a new sub-woofer first. If the sound still isn’t as you want it, then you may need to get your speakers changed too. When making these changes, enlist the help of a pro sound technician to be sure of the choices you make.


The warranty of the amplifier will determine whether you enjoy the benefits of your investment if a fault develops. It’s essential for you to check your product’s packaging, whether it comes with a warranty. To be totally safe, check for the warranty online before you even make the purchase!

Also, know that there are sellers that render the warranty of an amp invalid. Ensure you purchase your amp from an authorized dealer. Such a step will make sure your amp’s warranty is intact, and your money well-spent.

Proper wiring:

The wiring of the amp to your subs and speakers will determine the depth of sound produced in some cars. When it comes to wire installation, price equals quality in many aspects. Get the best wires you can find and fit them with your amp-sub-speaker connection. This will promote a better sound supply, and it may be what your car has been missing.

FAQ Of Class D Amplifier

Q-1. Do I Need to Change the Speakers in My Car to Use a New Amplifier?

Ans: This depends on the type of speakers in your car. If your speakers have a combined capacity that can hold a good percentage of the total RMS supply of the amplifier, then you can use the old speaker. But if you want to be on the safe side, you can get a complete overhaul with new speakers for your car.

Q-2. Do I Need a Sub-Woofer for My Amplifier?

Ans: It is advised you make use of standard woofers at the least when looking to optimize your amp’s performance. Sub-woofers in the mix will deliver more bass to your car’s sound and will make the amplifier perform better. It is advised you install a sub-woofer for your amp at the rear of your vehicle.

Q-3. What Does Class D Mean on My Amplifier?

Ans: The class of an amplifier refers primarily to its design and specifications. In the design of sound amplifiers, there are Classes A, AB, C, and D amplifiers. A and AB amplifiers are of inferior quality based on their design and output. The most desired, high-quality amplifiers are class D amplifiers.

Q-4. Where Should I Set-Up My Amp?

Ans: There are many places in your car where your amp can sit comfortably. But the best place to put your amp is an area out of easy reach and where there’s airflow. Sites such as beneath your trunk should be considered if the padding of your trunk isn’t heat-absorbent. You can also choose to have it installed under the rear seat in your car. Any of these two positions will work just fine.

Q-5. What Does Impedance Signify?

Ans: Impedance simply means the amount of power required by the amplifier to perform. It can be measured using the resistance detected by the load.

The impedance is the determinant of the threshold for the amplifier’s load when you’re looking towards having a decent performance from your speakers.


It’s a fact that some amps are made to outperform others. But on the flip side, it’s necessary to note that the amp with the highest and most impressive specs doesn’t translate to being the best for your car. The best option for you is to do some research on what’ll work best for your vehicle. When making this decision, put your current speakers and subs in the mix to get the right choice. I’m confident that with this review and guide, you’d get the best jams in your car in no time!
