XD700/5 – JL Audio is one of the best amplifiers in the market currently. It will provide you the high value of money. This potent amp is smallish, powerful; provide clean sound with unprecedented efficiency. It has lots of features. It’s most important features are NexD™ switching technology, advanced rollback protection, 3way protection circuitry.

PWM (Pulse Width Modulation) design approach of NexD™ switching technology provides consistent power to the modulator. So that you will get the clean sound without distortion by power supply fluctuation.

By using this amp you don’t need to worry about the annoying thermal shutdown. Because It’s Advanced thermal rollback protection eliminates thermal shutdown to keeps the music playing, even in most demanding conditions. When this situation arises amp thermal red led light will indicate it. After amp gets out from this condition this thermal red light indicates revert to its normal state.

Moreover, this amp has automatic turn-on capability via signal sensing or DC-offer sensing. You can control amplifier level from the driver seat through HD-RLC remote level control. By the way, You have to buy this remote level control separately.


KENWOOD has reputation for providing performance, quality and value products. If you are searching a quality amplifier at the reasonable price, then

KENWOOD KAC-8406 would be the best option for you. It’s one of the best amplifiers in the market with reasonable price. You can setup it easily by their instructions. Its sound is so clean and loud. 

As like above amplifiers, it also has the MOSFET switching power supply which provides great impedance with low current consumption. It heats sink design control your amplifier overheat temperature.

However, it’s an AB Class amplifier and I recommended this class of amplifiers in buying guidelines. AB class provide the best efficiency than others class and it comes with both A & B classes features.


Rockford Fosgate R250X4 Prime is the amplifier which offers lots of features at affordable price. It’ gives you pure clean and loud sound quality. 

It will be pretty hard to find another amplifier like this because the features it’s offering at a low cost no one can beat easily.  

If you want to buy another amplifier with the features that it has, then it will be very costly. But this amp is far low price than others.

It’s over current protection, short circuit protection and overheats protection gives you peace of mind. Its variable low pass and high pass filter make your speaker alive, loud and clear. 

However, Rockford Fosgate R250X4 Prime also an AB class amplifier which gives you more benefits with low current consumption.



Rockford Fosgate is reputed mobile audio manufacturer company. Car amplifier is their prime services products. Rockford Fosgate R500X1D is their one of the innovative, sleek-looking, powerful performance amplifier product.

This amplifier is another great product of Rockford Fosgate in the market with the best value. The sound quality it produces is much better than others amplifier around this price.

It also has MOSFET power supply, as we mentioned before in first product review it has some advantage. Its best advantage is, it does consume low current for operating amp and produce high impedance.

However, this amplifier has overheat protection, short circuit protection, cast aluminum heatsink which help to keep cool your amplifier. All of these protections keep your amplifier safe and give you peace of mind.



If you want the best value-added amplifier with low price then I can say this is the best amplifier for you.

It comes with such a simple and lightweight design. You can connect your favorite subwoofer by one channel system. You can control subwoofer by remote. It can eliminate bass distortion and has ample power to produce great sound.


It will give you everything for installation including instructions. So that you can easily install it in your car. There is another good thing about this amp is, it has overheat protection system. That controls amp temperature. If amp gets overheated this system will automatically turn off it and don’t on it until it gets cool.

In addition,

if a speaker fails because of electric short then it’s protection circuit will cut off output and remain it until problem properly solve. These protection systems will give you peace of mind.

It MOSFET(Metal Oxide Semiconductor Field-Effect Transistor) is one of the features which need to must mention in this review. In today’s market, most of the good amplifier has this features.

This feature provides many advantages, one of the best advantage of this is – it produces high impedance with low current consumption.

This BOSS Audio R1100M” is the best choice if you want a great amp with low cost.


BEST BASS SPEAKER FOR CAR, best car speakers, car speaker review

Before going to buy the best amplifier for your car, it’s better to know about some terms which relate with car amplifier.

In order to buy perfect amplifier which suits for your car, you should know about these. These terms include the class of amplifier, channel, bass boost, RMS power and more.

It’s very important to know what each term indicate.

We described below 4 factors about car amp, which you must need to consider before buying any amplifier for your car sound system.

Class of amplifier is very important terms. It indicates structure and features of amplifier electronic circuit.

It’s related to characteristics of the amplifier, sound performance, and power dissipation.

There are 4 types of amplifier class.


  • Class A: Class A amplifier is one of the best and most desirable amplifiers. It provides best sound quality than others classes though it’s low signal distortion level. The problem of this class amplifier is high operating temperature. It happens because of its output the transistor does not turn off. It always has current running through them, even if there has no audio signal. For this reason, the amp gets heat up.


  • Class B: It’s invented with solutions of class A problem and It’s developed version of the class A. It’ has no efficiency and heating problem. Because It’ transistor turns off for half of every signal cycle. By the way, it tended sound distort at high frequencies.


  • Class AB: Class AB is the combination of Class A and B. It’s mostly similar to Class B amplifier. However, it’s also run current through output transistor but it’ allows much lower current than Class A amplifier.


  • Class D: This amplifier is the non-linear amplifier. You can control power distribution of output transistor by the switch. Comparatively class AB amplifier, it has tended to deliver higher distortion.

In order to make you more clear about Amplifier classes, we have given below a table about Pros and Cons of amp classes. 

Class A Highest frequency, sound reproduction Enegery inefficiency, high level operating temperature
Class B Low rate energy inefficiency, low temperature Tend to sound distortion at high frequencies.
Class AB Low operating temperature, Better sound frequency and sound reproduction, adequate energy saving Peak performance is lower than class A
Class D Save energy, low operating temperatures, low-frequency sound reproduction Humble high-frequency sound reproduction

So, which amplifier class will be better for you? What is our recommended amplifier class?

Well, our answer is Class AB will be better for your car. Its offer benefits of A and B both classes with maintaining the quality of sound.

Bass boost is a circuitry. It boosts the bass sound, improves the sound reproduction.

Some of the amplifiers keep this feature. So that, users could tune the bass boost by adjusting the center frequency.

Channel is the audio signal of the amplifier.

You can connect single speaker/subwoofer with the single channel output or more channels output with more speaker/subwoofer.

So, if you have the plan to connect more speakers and subwoofers then you must go this amplifier wich have more channel.


RMS power is a number of continues power that amplifier produces. RMS power indicates the sound quality of the amplifier.

If Higher the RMS Power, the amp will produce louder and clean sound quality.

So, you must notice it when you buy any car amplifier.
