Different Types Of 4 Channel Amps
Several brands produce 4 channel amplifiers for motorcycles. However, the better-known brands have made a name for themselves from the top power you can expect from their products. To get your hands on these, you would have to pay a little bit more – although the extra cost is worth every penny.
Most of the best 4 channel amps you will come across are so small that they should fit perfectly on your motorbike. However, a couple of brands produce relatively large amps. As such, you might want to check that the option you have your eyes on will fit perfectly on your motorcycle.
The watts your amplifier produces will determine the volume you will get. To this end, you need to consider the wattage of the speakers on your bike, as well as the subwoofer, so that you can choose the right amp.
Benefits Of Getting An Amp
1. Enhanced Sound Quality
Adding an amplifier to your motorcycle means that you will get to enjoy crisp, clean sound at every volume level. In fact, your external amp will take the clear pre-amp signals from your bike’s stereo and amplify it to the right RMS levels your speakers need without distorting the signal.
2. Power Aftermarket Speakers
If you choose to upgrade the factory system that your bike came with, one option would be to invest in high-quality speakers. However, this decision might disappoint you especially when you discover that the new speakers haven’t done much to change the quality of the signal from your stereo.
The best solution, therefore, would be to buy the right 4 channel amp. By so doing, you will get the right RMS – which will perfect the sound quality even after you’ve decided to raise the volume.
3. Amplified Subwoofer
Even if you buy a small subwoofer, you still need to get the best 4 channel amp if the factory stereo that is attached to your bike is to sound any good. The most potent of these amplifiers will produce better sound especially if you choose to bridge them to power the subwoofer.
Choosing The Right 4 Channel Amplifier
While shopping for the other audio components for your bike, you should think about the price. Of course, you certainly don’t want to invest a lot on a 4 channel amp for speakers that are only going to give out horrifying sounds.
Needless to say, you might also think about going for something that is a bit on the higher end of the spectrum in terms of pricing as you shop for the best 4 channel amp. In fact, this is one of those add-ons where the price is directly related to the quality of output.
However, we would advise that you balance quality with the price you are willing to pay. Otherwise, there’s no point wasting your money on a product you apparently can’t afford.
b) Peak Power
Peak power, where the best 4 channel amp is concerned, refers to the maximum power output that you can run on an amplifier. For instance, if the amp you wish to buy comes with a peak power of 400 watts, you shouldn’t hook components with a total of 600 watts to it – you will only damage the system.
Our advice: buy a 4 channel amplifier that comes with enough fuel to power all your components.
Like with any other electronic device, even the best 4 channel amp is bound to fail at one point or the other. However, you certainly don’t want to buy an amplifier only for it to stop working after a couple of days or weeks.
To protect yourself from this eventuality, only buy 4 channel amps that come with a warranty from the manufacturer. Lucky for you, most of the best 4 channel amps – certainly all of the ones we’ve added to this guide – carry manufacturer’s warranty.
As we mentioned above, you should not buy an amplifier until you are sure that it won’t take up too much space on your motorbike. While shopping for a 4 channel amp, therefore, check the size to make sure that it is the right fit for your bike.
Overall, finding the best 4 channel amp should not be hard – especially now that we have supplied you with our top 5 recommendations. Irrespective of the choice you make from the suggestions above, you can be sure that you will get the quality output you are looking for.
Our best bet, however, would be the Kenwood KAC-M3004 Compact 4 Channel Digital Amplifier. Durable, stable, reliable, and complete with manufacturer’s warranty, this product comes from an established brand in the sound market. Therefore, you can never go wrong with it.
