Buyer’s Guide

Now that you’ve seen the top models, it’s time to talk about how to choose the best one for you. Here are some crucial factors to keep in mind when making your decision.

System Requirements

The reason most people buy an amp is to enhance their sound system. Amps specifically enhance volume and bass. While the objective is straightforward, you must ensure the amp has power ratings that work with your system’s requirements. The most critical power ratings are RMS and MAX. 

Though it may seem counterintuitive, overpowering your speakers is better than underpowering them. Underpowering can actually damage speakers and subs, so the RMS rating must be higher than that of your speakers.

Budget

In doing your research, you’ve likely realized that there are many amp options. Setting a budget can help you narrow the field if you’re feeling overwhelmed by the choices. 

If you don’t want to, there’s no reason to spring for a product way over your budget—especially if a cheaper one has all the features you want. There are many quality products at affordable price points, and class A/B units are an excellent option for anyone who wants to keep costs reasonable. 

Sound Quality 

Sound quality should be a priority, as any amp worth its salt should be capable of producing music with no distortion. High-quality amps should also cancel noise out, so pay attention to brands that have distortion-avoiding technology. 

Bridgeability 

You also want to keep bridgeability in mind when searching for the best 5-channel amp for your vehicle. Keep in mind that the best models are designed for five-channel systems, but bridgeability allows you to use them with three-way systems. 

Lots of people prioritize this feature for the flexibility it affords. If you think you may need to reconfigure your car’s audio system at any point (and even if you don’t), it’s worth getting a bridgeable model. Plus, there’s plenty of options, making them easy to find.  

Impedance

Lastly, it’s vital to check the impedance rating before purchasing a car stereo amp. 

The impedance rating tells you how hard the amp has to work to generate power, and it’s expressed in ohms. A low impedance rating means the amp doesn’t have to work hard to generate power. On the other hand, a high impedance rating means that the amp must work harder to produce quality sound. 

To work properly, the impedance rating of your amp should match that of your audio system. Most 5-channel amps have a rating of 2 ohms or 4 ohms. 

Conclusion

While any of the 5-channel amps on our list can improve your car’s sound system, I found that the Rockford Fosgate R600X5 had a slight edge on the competition. It’s easy to use with any audio systems, even factory ones, and the combination of class A/B and class D delivers superb listening quality. 

All of its channels are well balanced, the amp features solid construction, and it’s got excellent reviews. Many happy owners are pleased with their purchase from this well-respected brand. If you’re looking for the best 5 channel amp for your car, shop the Rockford Fosgate R600X5.
