Amp Class: D
Bridgeable: Yes

Judging from its price, you’d expect nothing short of phenomenal from this amp. True enough, it delivers just as much. The JL Audio XD700/5 amplifier brings a blend of the latest amp technology and a range of exciting features to the table.

Any audiophile would be pumped upon an encounter with this piece. Its NexD switching design simply takes its efficiency to a whole different level.

These and other features impressed us enough to make this JL Audio 5 channel amp our top pick in this section. The JL Audio is clearly not messing around in its effort to give the market a state-of-the-art car amplifier.

Its max power output falls at 700 watts at a stable 2 Ohms. While this may not be the highest RMS output in the market, it is enough to handle a top-level sound system. When bridged, its minimum impedance falls at 2Ohm and at 4Ohms unbridged.

JL Audio hardly ever disappoints; this includes their regard for safety and device durability. As a safety measure, this amp features JL Audio’s signature Advanced Rollback Protection. A really fascinating fact about this feature is that it rolls back peak power output when the amp gets to an alarming temperature; it holds the low power output until the device cools down. If that doesn’t keep the amp from substantial damage, I don’t know what would.

Additional features include its aluminum allow heat sink chassis, speaker level inputs, a differential balanced input section, selectable filter mode, and a fuse rating of 60A. It also supports an HD-RLC remote level control which is sold separately.

What does a 5-channel amp mean?

Now typically, an amplifier is designed to boost low output sound signals from an independent source to more elaborate, powerful, and cleaner signals. Usually, an entire sound system (inclusive of a subwoofer), requires you to pair up a 2 or 4 channel amp with a mono-block amplifier to adequately run it.

Sounds like one heck of a task, doesn’t it? Well, fortunately, that’s where a five-channel amp comes in. It allows you to run your entire sound system through a single device.

A 5 channel amplifier is a hybrid; a combination of a 4 channel amp and a mono-block amp in one package.

In other words, it is a fusion of both Class D and Class AB circuitry in one chassis. With it, you have four channels to power your front and rear speakers and a fifth channel specifically for the sub-woofer.

So, 5 channel amplifiers save their users the wiring nightmares that come with having multiple amplifiers.

We also did a review of 2-channel4-channel, 6-channel, and monoblock car amps.

Why A 5-Channel Amp Is A Better Option?

Amplifiers have seen quite the evolution in the past few decades. At one point, if you had any intention of setting up a full-range sound system in your car, it meant sacrificing a good amount of your cabin and trunk space.

Since their conception well over a decade ago, 5 channel amps have gradually gained popularity due to their heavily convenient nature. Naturally, this amp brings quite a lot to the table including a bunch of advantages.

Benefits of 5-Channel Car Amplifiers

More Power, Less Space

Instead of having two or more amps, a single 5-channel amp can get the job done just as well comparatively causing less havoc. This hybrid not only saves you a significant amount of space, but it also does so without sacrificing the much-needed amp power. By bridging it, it allows its users to boost its power output when the need arises.


You’ve got to admit, being able to serve a full set of sound components with a single device is remarkable. What makes it even better is that the prerequisites involved are very easily achievable. 5 channel amps are undeniably more favorable in terms of space, power, and even cost.

For people who would rather deal with a single amp than have to juggle around several of them in an attempt to get the desired sound blast, 5 channel is the way to go.

Top-Notch Delivery

By using a fusion of Class D and A/B amp technology, 5 channel amps give exceptional results. With a cleaner sound output, lesser background noise, and more defined music waves, it is impossible to deny its efficiency.

What Should You Look For In A Good 5 Channel Amp?

The market is flooded with different 5 channel amp models. While this is mostly a good thing, it can get rather confusing especially if you have limited knowledge regarding amplifiers.

Acknowledging this fact, we’ve come up with a list of features you should put into consideration when assessing a potential 5 channel amp buy.

RMS Power

RMS (Root mean square), usually measured in Watts, represents the total amount of continuous power an amplifier produces.

Most 5 channel amps are capable of running between 600-1000 watts RMS. Even so, there are several models capable of running more than the above-specified range of RMS.

Regardless, more RMS output always means more power. In simple terms, the higher the RMS the better the outcome.


This is basically the measure of electrical resistance. 5 channel amps come with an impedance measurement of either 2 or 4 Ohms.

However, depending on the nature of your sub, you may need to go slightly higher than this to a probable 8 Ohms. Needless to say, you should make sure the amp’s impedance matches that of your system for a smoother operation.

Peak Power

It refers to the maximum amount of power an amplifier can handle in a short period of time without burning out. This may not be as important as the RMS measure. Even so, the peak power can also make or break an amp.

In Relation To Your Car (Prerequisites)

When making this nature of the purchase, keeping your vehicle’s features in the back of your mind is very important. In as much as an amp may have all the right specifications, it may not be well suited for your car.

Additionally, it may not work as well for your own preferences. With that said, here are some additional factors you should consider before and during making that much-anticipated purchase.

How Big Is Your Car?

Normally, the size of the car determines the number of speakers or sub-woofer you can fit into it. On the brighter side, 5 channel amps come in considerably compact designs.

However, some models are still larger than others. That said, space determines the amplifier model that works best for the conditions in question.

Your Music Preference

Inbuilt car sound systems may not always work harmoniously with all genres of music. Seeing as much, you may have to add on speakers to achieve your desired output. Whether a deep bass or soft, delicate music, your amp should be capable of handling your music choice sufficiently.


Cost is a major determinant of the type of amplifier you eventually end up with. As you would expect, good 5 channel amplifiers don’t come cheap.

This, however, does not mean you cannot find a good quality one at a reasonable price. The market has an endless list of options at different price levels. Despite the fact that the search may be daunting, finding one that falls right into your budget is guaranteed.

With the much that has been said, it is about time we got the gist of this write-up. In a market where the privilege of choice is more of a headache rather than helpful, a simple guide goes a long way in informing any given amp shopping spree.

Hey there mobile audio lovers! My name is Vincent Talbot, founder and chief editor at 99carstereo.com. Ask any mobile audio fanatic, installer, or company rep what makes a good car speaker, sub or amp, or, better yet, why he or she prefers a certain brand over another, and be prepared to endure a litany of opinions, viewpoints, and passion-fueled perspectives. To be honest, mobile audio shopping can be a daunting task without a guide, so I’ve assembled what I feel are the best products to consider to make things easier for you. Welcome aboard!

Why you should trust me?

Mobile audio is my passion, so before I put anything in front of you I exhaustively research a broad range of products, review all the available information on them and ultimately make a curated list of recommendations. My goal is to recommend products that will serve you well so that when I extend this site to include more products, you will come back.
