Cheap amplifier for car speakers

In this article: We'll review everything you need to know to figure out whether or not you need an amp in your car to improve your sound. Instead, it is the head unit or speaker grills. Still, the car amplifier is one of the most essential components for high-quality sound. With premium audio systems, the amplifier might be more powerful, but is still nothing compared to what you can create with aftermarket equipment. In any system, the amplifier takes the audio signal and literally amplifies it. They might have a low impedance voice coil or another attribute that makes them incompatible with most aftermarket amps.

The Best Budget Car Amplifiers For Under $50, $100, & $150 + Amp Buyer’s Guide


In our view, an amplifier is an investment that pays dividends in the long-term since it can be enjoyed every day and they typically survive the longest among car audio components.

If you are customizing your own high-quality car audio setup, you should never consider a car amplifier as an afterthought. This is because the best car amplifiers can power aftermarket speakers , subwoofers , and other pieces of audio equipment that are essential for full range, loud audio playback. To help you put together the best car audio rig possible, we put together this guide to finding an excellent car amplifier for the money.

Below, you will find comprehensive car amplifier reviews to help you put together the best car stereo system for your ride. Not all amps are the same. There are two main varieties of car amps on the market: mono amplifiers and multi-channel amps. To begin, we will start by going over the best mono car amplifiers and discuss the various advantages of several models. Mono amps deliver power to a single speaker channel, usually a subwoofer.

Therefore, there is only one audio signal that is transmitted and, as such, this amp type is best suited for low-frequency system designs.

The Rockford Fosgate RX1D is one of the best car amplifiers on the market today with great sound quality. With this product, you will want to use a 75A alternator if you want to provide it with a safe amount of power.

Beyond that, the on-board Punch EQ system boosts the system up by 18 dB at 45Hz which adds a nice touch to the amplifier that others in its price range are sorely lacking. However, the input sensitivity is a bit on the low side at only mV to 4 V.

Thankfully, the RXD boats a fully aluminum heatsink with a stealth top mounted control panel which makes the unit appear sleek and minimalistic to the untrained eye.

The only drawback regarding aesthetics is that it comes with a wired remote which can be an eyesore and frustration at times the upside, however, is that you never have to change batteries. Regarding energy efficiency, this system performs quite well with your car stereo.

The amplifier is CEA compliant and reduces the energy load from the power source before transmitting to the loudspeaker or the subwoofer. Best of all, it takes up little space as it is only 8. The amps performs quite well given the modest price tag as it provides plenty of reliable power for a mono-channel system.

There is virtually no consumer-grade loudspeaker or subwoofer that this amp would not be able to power. Plus, there is 1-Year short circuit protection for added peace of mind.

The Boss Audio RM is a budget-friendly power solution for your custom system. The technical specifications on this unit far exceeded the expectations we had when we saw its relatively low price point.

An watt Monoblock, with the option to upgrade as high as watts, the RM is a reliable high-power amp for powering mid-to-high level sound systems. For those who love to have more power contribute to the bass or treble of their audio, this amp lets users tweak the power supply with a variable low pass filter crossover and switchable bass boost dial.

Aesthetically, this model is excellent. It features a crisp BOSS logo on the front that is backlit by a blue LED, and the metallic finish gives the impression that this is a premium-grade device. Although larger than most other units in its power range, this car amplifier is compatible with virtually all chassis types as it is less than Performance-wise, we were pleased with how the Boss Audio RM held up, even when powering a heavy subwoofer in the trunk.

Although the Boss brand is not exactly synonymous with high performance, this model has no problem powering a inch comp subwoofer without fail. Plus, the plug-and-play setup process makes installation a breeze. Providing 1,W at maximum power, the D is a compact car amplifier that is small enough to be installed in any car chassis. Versatility is the main selling point with this unit. A small-but-mighty device, the D is dramatically more powerful than its Class-D counterparts, and its speaker level inputs allow users to connect any OEM unit without having to buy an adapter.

Consequently, installation is easy since it has a basic plug-and-go functionality. Weighing only six pounds, you will be astonished by the lightweight form factor of the D But do not let looks deceive you, because this device can pump out W rms to a 2-ohm speaker and up to W rms to a 4-ohm. Overall, this is a great name-brand car amplifier. The Class-D technology makes good use of the amp load, which can be ground through eight-gauge power wire which we heartily recommend!

However, a sub-par warranty and a relatively short lifespan hold us back from giving this device a perfect rating. At 1 ohm this device can power an astonishing watts or watts at RMS power. Plus, an intuitive remote subwoofer controller makes adjustment simple without having to get up and deal with finicky dials. If you need an extremely powerful Monoblock amp , the RP may be the right option for you.

A high-speed MOSFET power supply and a neatly-organized 4-way circuit board ensure that short circuiting and other power-related defects do not occur. In our experience, the RP is a solid car amplifier for powering a pair of W subwoofers or loudspeakers. At this power level, you can expect zero clipping or performance drop-offs. The perfect addition to any system that needs serious power for loud output, the RD is as good as it gets at its mid-level price point.

Most of the mixed reviews online point to the fact that this products can sometimes put itself into protection mode if wired incorrectly. If you fail to ground the amp properly, you may also run into the same issue.

Therefore, we advise always taking extra care to ensure that the power wire is attached correctly. Luckily, Skar Audio has excellent customer support for wiring advice. Since most 2-channel amps can be bridged, they can also power a subwoofer. When we first opened the box and held this amp in our hands, we had a hard time believing that it could supply watts RMS to two speakers concurrently. But, after a brief test run, we were blown away by how clean and crisp the sound quality was at this power level.

In the one-channel mode, this amp provides up to watts RMS to a subwoofer, which supplies enough bass to rattle an entire house. For added convenience, you can use the wired remote to adjust bass levels from the front seat, which fine-tuning a simple, no-fuss process. At just over one and a half pounds, this amp is deceptively powerful for its size. For its size, you would be hard-pressed to find any other model that can supply W RMS at 4 ohms through a bridged output.

Unfortunately, there are no on-board fuses with this device. Consequently, you need to attach a amp inline fuse to the distribution block if you want to install more than one amp in your car sound rig.

Definitely consider this unit as you look for the best car amplifiers. An affordable 2-channel amplifier solution, the Planet Audio AC is one of the best W bridgeable amps on the market. Featuring an incredible 6-Year Platinum Online Dealer warranty and a sleek, blue LED backlit design, this amp is both beautiful and reliable for long-term use.

In 2-channel mode, this amp can supply W maximum power at 4-ohm. At its rock-bottom price point, it is virtually impossible to find an equally-powerful model in the 4-ohm range. If you like to adjust the output so that it perfectly suits your preferences, you will be pleased to find that this amp has variable low and high pass crossover and bass boost functionality.

Those concerned about short-circuiting will be glad to find out that this amp has short protection, making power or heat-related issues a non-factor. At a modest six pounds in weight, this device is more than capable of supplying a respectable amount of power at a low cost. While not the tops in our best car amplifiers list, this unit still deserves solid mention for what it provides in power output and overall performance.

Unlike mono or 2 channel amps, 4 channel amplifiers are designed to supply power to four speakers, one for each corner of the vehicle. These amps are ideal for heavily customized systems. Please refer to our guide on the best 4 channel amplifiers for more products. The MRV-F is a great-sounding amp that is housed in a beautiful dark-colored metal chassis that weighs less than five pounds. Using an eight-gauge power wire, it is easy to connect inputs to the amp since each connector is neatly labeled and feature hex-key screws.

At this performance level, the sound quality is excellent and adequate dynamic thermal cooling makes overheating at any power level a rare occurrence. The main benefit of this budget-friendly 4 channel amp is its small chassis.

At 72W per channel at 4-ohm and W per channel at 2-ohms, the PX4 is one of the best car amplifier solutions if you want serious power across four channels. If you want a hassle-free installation process and a sleek, professional-looking amplifier to power every corner of your vehicle, this might be the amp for you. Although it weighs 12 pounds, you will not be disappointed with the performance quality of this 4 channel amp.

However, users should be aware that this amp might not be suitable for powering a 4-way system with multiple inch subwoofers at 4-ohms. A 5-channel amp is a perfect choice for a complete audio system. If you only want to use one amp to power four loudspeakers and one dedicated subwoofer, a 5-channel amplifier provides a hassle-free solution. Please refer to our guide on the best 5-channel amplifiers for more products.

The Alpine PDX-V9 is one of the best high-performance 5-channel amplifiers if you want reliable, short-free power for a single subwoofer and two loudspeakers in the front and back of your vehicle. Installation problems are a non-issue with this amp, as its Quick-Connect setup system is among of the simplest when it comes to 5-channel amps.

At a lightweight 7 pounds, you would be hard-pressed to find similar performance in an amp of this size. Plus, its stackable chassis makes it perfect if you want to upgrade to a multi-amp setup. If properly wired, you should be able to supply five high-performance speakers with clean, clipless sound even at high frequencies in the kHz range. The Rockville dB55 is a full range and budget-friendly 5-channel amp for loud, car-shaking sound output.

If you want the best car amplifier for a highly customized internal sound system, the dB55 will likely give you the best value for your money.

Providing W or W RMS across five channels, this device is an excellent choice for serious enthusiasts. Instead, this amp features best-in-class sound quality for its price. While the setup process is simple, and short-circuiting is a non-issue thanks to an IC-Controlled Protection circuit design, there is still the possibility of overheating due to a lack of proper internal cooling. A pulsed magnet is used to cause the internal membrane to vibrate, moving the air in order to create a variety of pressure waves that are interpreted as sound.

The larger the membrane the quicker it will vibrate, resulting in the need for more power. The issue with this setup is that while a lot of power is needed for certain models of speakers, the same amount of power can also tear the membrane on a smaller set of speakers, a process which is referred to as blowing out your speakers.

And because of this common issue, the average stereo systems in cars will only offer a limited amount of power to the output, in order to ensure that the stock speakers are not damaged the moment you turn them on. If they do make sound it will definitely be at the expense of the speakers.

How to Build Your Own Custom Car Entertainment System


By: Patrick E. Let's say you've invested in a new set of upgraded speakers and a sleek new stereo receiver unit. You're on your way to hearing your music in superior ways. However, your car may not be doing your custom audio system justice -- and your radio's built-in amplifier might not supply enough power to the new components.

Amplifiers take a signal from the stereo and use an independent power source to change it into a more powerful signal for the speakers.

Your Shopping Cart

For years some car amp manufacturers have sold their products with outrageously large power ratings on the box. Sometimes these have been simply unbelievable for a budget car amp. Think of it like the example of a modest-sized car with a speedometer that goes up to MPH. Can most average cars really drive that fast? No way! I recommend at least a power rating of 50W RMS into 4 ohms per channel for driving full range or component speakers and W into 4 ohms minimum for driving a subwoofer.
