Things to Check Before Getting One 

Though you know about the Best 6.5 motorcycle speakers, you have to be careful to select the suitable product for you. There are a lot of products you can get, but there are some things that you should check to get one. Don’t worry. We will make that easy for you; you need to check the sound quality, durability, and hardware compatibility before getting one. 

Sound Quality 

All speakers have different sound outputs compared with the power handling known as RMS. The speakers with greater RMS give better sound output and crystal clear audio experiences and bass in any scale of volume. The RMS does not depend on the size of the speaker; the smaller speakers can have a good RMS value compared to bigger ones.

6.5 Motorcycle Speakers


The motorcycle speakers will get exposed to the outside environment. You don’t want your favorite speaker damaged, so the durability of the speakers is essential. You should buy speakers which can withstand the weather conditions. The Manufacturers provide some features which will increase the lifespan of the speakers. You can purchase the product by considering these features. 

Hardware Compatibility

Purchase your product that will be suitable for your motorcycle. It will be challenging to install speakers according to your bike hardware. The wrong speakers can cause lots of hustle, like cutting the bike frame or upgrading hardware to fit the speakers. It will cause more money and time.

Loudness Level

Hardware Compatibility

The groovy engine sound of your motorcycle might be one of your favorites. But you also need to hear the engine roar on the speaker system you install in your motorcycle. This is why the loudness level is very important.

You should go for a speaker system that produces loud enough sound for you to hear even at speeds more than 40 km/h. To determine the loudness level of a speaker system, a parameter called dB-SPL (decibel-Sound Pressure Level) is used. This parameter depends on the wattage of the speaker.

To clearly hear the sound even after the interference of engine howl and road noise, the speaker you buy should have at least 90-100 dB-SPL. These speakers usually come in 600 watts but some powerful speakers can even come in 1000 watts.

Mounting Locations

Mounting the speaker in the right place is key to having excellent audio while riding. As motorcycles don’t have an enclosed space like cars, sounds produced by speakers don’t circle around. Rather, they get spread too quickly and you hear only a bit.

This is why you need to mount the speaker on the front of your motorcycle. As the design of motorcycles is very compact, you don’t have much space for customization. These speakers are most suitable to mount on the handlebar.

Most of these speakers have mounting brackets with them. So, you can simply clamp the bracket on the handlebar. The main benefit here is the sound is projected directly towards you so that you can get clear audio.

Just remember not to block any control of the motorcycle in the process.


Both wired and wireless speakers are available for motorcycles. Wired speakers are a bit difficult to handle while riding. Connecting your devices with the speakers is a big hassle. Wireless speakers are great for having fun without any extra fuss.

6.5 Motorcycle Speakers

So, the speaker you buy must have Bluetooth connectivity so that you can connect to other devices effortlessly. But if the speaker doesn’t have wireless connectivity, you can use Bluetooth adapters to make them wireless.


Though we often ignore this criterion, this is quite important. As the speakers on motorcycles aren’t enclosed, they are susceptible to being exposed to moisture. So, these speakers should have a decent waterproof rating that will ensure the speaker takes no damage even after being exposed to such threats for a long time.

How to know if my selected speaker is loud enough for highway listening?

We can determine the loudness of the speakers with the sound sensitivity, which is measured in decibels. The higher the decibels, the louder the sound is. The speakers with a minimum of 81 decibels of sound sensitivity will be loud enough to listen to the highways. So get a speaker above 81 decibels and rock and roll at the roads.


Though we try to tell almost everything about speakers, you may have some questions moving around your head. In this segment, we will try to answer the most asked questions about the speakers that will help you to get the most fitting product. 

Q: What are the loudest 6.5 motorcycle speakers?

As we previously informed, the speaker’s output above 81 decibels is considered the loudest one. All the speakers who have broken this limit can suppress the highway noise. You can find many speakers with a higher decibels rate.

Q: Are these speakers plug and play?

Yes, all the listed speakers are plug and play. You just need to connect it with the power source, and your speaker is ready to play. For operating the speakers, you don’t need any manual configuration.

Q: What are marine grade 6.5 speakers?

Marine-grade speakers are specially designed for withstanding water and extreme sunlight exposure, and it is different from standard automobile speakers. These speakers are waterproof and UV protected and can survive in any environment. 

Q: Do I need an amplifier to use 6.5 motorcycle speakers?

Most of the speakers have a built-in amplifier, but that isn’t enough for getting maximum output. As the preinstalled amplifiers are not capable of delivering the full power, For having a maximum output, you can use another dedicated amplifier, and it will supply more power to your speaker. 

Q: Can I power the speakers with a power supply of 12v 2 amp? Any requirements in terms of amps?

The amount you will get from 12 v and 2 amp is 24 watts which will be enough for home speakers. But if we are talking about motorcycle speakers, it may not be enough because less power consumption will produce a less loud sound that can’t break through the highway noise. 

As you previously stated in your article, speakers with higher RMS ratings can influence highways. So we will recommend you to deliver higher power t by using amps. Every speaker has a peak power handling limit, and you should not cross that limit. otherwise, your speaker can be blasted away. 

Final words

We cover everything to find the best speakers, and you are ready for getting the best 6.5 motorcycle speakers. It’s totally up to you what you will pick up from the list. 

Before buying a new speaker, always check the sound quality and durability of the speaker. You may need a good amplifier to get the clear sound and bass at every type of road. If you are not an expert in installing the speakers go find a professional to install them. So get your speaker and enjoy the road trips.
