Buyer’s Guide for the Best Motorcycle Amplifier
Now that you’ve come a long way reading these reviews, let me guide you on how to successfully purchase the best motorcycle amplifiers. There are many key features and specs you need to look at. Amplifiers can be confusing, especially to newbies who often go for wrong parameters such as, for example, peak power rating instead of the RMS power rating. I will define some common terms worth knowing.
What to look for when buying motorcycle amplifiers?
Number of channels
The important to consider when buying motorcycle amplifiers is to match them with your speakers and subwoofers. You may be planning to power a single subwoofer, double subwoofers or 4 speakers. For each of these choices, you should choose the amp accordingly. For instance, the RMS rating and the impedance tell us how capacitated the amp is to power your system. Moreover, amps are classified according to the number of channels: 1, 2, 3, 4, 5, and 6.
Other channels can be bridged to offer the best power output to numerous speakers. Stereo amp (referred to as 2-channels), is the most common one on the market. It can be regarded as 2 independent Mono-channel amp with independent outputs. Alternatively, a single channel can be bridged and the other left unused in stereo amps. Ideally, the number of speakers to power depends on RMS power output and the channel type. With a 4-channel amp, you can build an impressive audio system.
Of foremost importance when making purchases is to differentiate between different types of power ratings. Oftentimes, amp cases are printed with the peak power as the maximum output, which is basically an instantaneous power increase for seconds. The RMS power rating is the real reflection of the continuous power the amplifier can generate consistently given a certain impedance.
The power rating gives a true reflection of the efficiency of the amplifier. For this reason, beware of inflated power ratings. Always look for the amps that comply with the CEA (Consumer Electronics Association) 2006 industry standards of power rating as the assurance that the figures are accurate.
And, when setting up your motorcycle audio system, check the compatibility of the speakers and the amplifiers. My first product, for example, comes with speakers that are already fine-tuned to work properly with the amp. Most amps require separate purchase of speakers.
Other features to consider include the low and high pass filters. Low pass filters are involved in the cancellation of higher frequencies whereas the high pass filters do the opposite. There are many features to look for, however, these ones are the most important.
If you ride mostly in unfavorable weather conditions, you may want to consider the weatherproof, waterproof, and water-resistant amplifiers. Some come with the conformal-coated printed circuit boards that protect against moisture. The amplifiers are sensitive to water damages. It is therefore important to ensure that they are weatherproof.
Furthermore, the amplifier has to be adjustable to make installations easy. Some come with mounting brackets or any other hardware to install them. Even more, the design and the compact size of the amp should be looked at.
Where is the right place to install amps on the motorcycle?
These amplifiers can be installed in any place where they can be conveniently accessible by the driver. Oftentimes, they are installed on the handlebars, saddlebag, and tank bag or under the headlight. Even under the seat provided, there is enough space they can be installed. As you install these amps, make sure you do not obstruct the audio inputs where you should connect USBs, smartphones or memory card readers.
What is impedance in amplifiers?
Impedance, measured in ohms, is a measure of resistance to current flow in the electrical network. These amps may have different RMS power output per impedance. The higher the impedance in ohms, the lesser the current flow.
We have come to the end of the best motorcycle amplifier. I have reviewed the best products on the market. When making purchases, make sure you familiarize yourself with the RMS power rating, impedance and the number of channels. Most of my products are 4-channels, which is the most common to plan a large audio system. The 2-channel amps also follow as the most common on the market.
The best way to enjoy motorcycle rides is to upgrade the OEM music system. These amplifiers can power numerous speakers including subwoofers. Others come with low and high pass filters, and so it should be easy to have control over the frequencies.
There are more features to consider before making purchases. For instance, the amp has to be waterproof, water-resistant, marine compliant and weatherproof.
