Speakers for Harley Street Glide – Buyer’s Guide!

Why does your Harley stereo system sound bad? Good question. Speaker quality and lack of power at speed are the first thoughts that come to mind. Poor SQ or lost signal going down the road, bass loss at speed with all that engine/wind/road noise is making it even worse.

Low efficiency, weak factory head unit, constantly hot amp that keeps shutting down… Who needs that?

Another issue is that factory speakers are 2ohm and most aftermarket are 4ohm. Also, on most 2way aftermarket speakers, the center-mounted tweeter sets too high and hits the factory speaker grille.

The thing is that a manufacturer looks over every single part of a vehicle with a cost in mind because saving a few bucks here and there adds up to lots of money when you sell thousands of vehicles. Unfortunately, it’s your sound system that pays the price.

Harley speakers were not designed to sound great. True story. They were just a means to an end. When you’re at a standstill that may be fine. But is that supposed to be enough? You don’t want to just listen to the music with your engine off, right? And you don’t need some noisy speakers just because they’re loud at speed. This means you need quality, so here comes the aftermarket.

Fortunately, there’s always room for an upgrade to make the sound of your bike exceptionally good with a set of great-quality speakers and/or an amp while keeping the stock look. Find the benefits of the top 5 speakers to find the best solution for your bike from the list below.

  • Certificates and warranty availability.
  • Reliable protection against vibration, rain, and moisture.
  • Really wide frequency range.
  • Surround and clear sound.
  • Simple controls (switching functions, track selection, volume control).

How to Choose Harley Speakers?

Decided that you need to buy a sound system for your bike, you should understand the features of acoustics for such a vehicle.

  • Don’t forget about the size. For dynamics especially, size matters.
  • Pay attention to the built-in power. The sound system should be powerful to interrupt the roaring sound of the engine + absolutely hermetic.
  • Make sure that the controller is located in a convenient place. Most modern audio equipment can reproduce all common audio formats and radio stations.
  • Make sure that fastenings are reliable and all mounts are fixed.
  • Make sure the body material is resistant to corrosion / abrasion / moisture and does not fade in the sun.
  • The audio intensity of the audio system should be at a very low level. Otherwise, after a noisy disco in the wilderness, you risk simply not starting your bike.
  • Sound system must withstand overloads and shakes, be resistant to strong vibrations and harsh weather conditions.

Otherwise, it will be enough for a couple of trips in good weather. Dust, water, and dirt will spoil even the best sound. And in the end, the system simply stops working. It will be extremely difficult to restore it.

It is also worth paying attention to possible noises and crackling when checking your speakers. To achieve high-quality sound from audio systems on such a vehicle can be quite difficult sometimes.

Most of the necessary elements are already included in a set, which you can buy with a sub:

  • Speakers
  • Bases
  • USB cable
  • AUX cable
  • Power cable
  • Set of clamps
  • Fastening rings
  • User manual
  • Box for reading off audio from a drive
  • Set of tools for high-quality system installation.

The most common coaxial speakers’ options go with three heads: for bass, midrange and high frequencies. The advantages are a compact and extended range. 3 loudspeakers are installed in the same place, which makes a more powerful and richer sound.

For clearer surrounding sound, you can always add a sub, which will also make a better bass.

  • This is a great article and has been very helpful in my decision, but I have one more question… Are any of these not ok in wet conditions. I get caught in rain sometimes, wash bike occasionally… I certainly wouldn’t be playing music in wet conditions, but can they handle moisture from time to time?

    • Thank you for your question. Well, first of all, no Harley speakers are 100% waterproof, no matter what they say. Some parts may be well-protected, but others remain exposed. They can be water-resistant, but it’s not like you can ride your bike through heavy rainstorms without consequences. Having speakers installed on your bike is a responsibility in a way that you have to check those weather forecasts more often. Otherwise, chances of getting poor sound or totally wrecking the speakers are huge even if you don’t turn them on in the rain. They can survive a few rides under the rain but will suffer the consequences for sure. No matter how expensive they are – that doesn’t mean anything when it comes to protection from water. So whatever you are going to buy, it’s best to keep your speakers dry and avoid humid conditions. You don’t want the water to get into the electronic components and cause shorting out.

    • Yes, they can. Reasonably. None of these speakers are fully waterproof. However, most of them are moisture-resistant (e.g. Rockford Fosgate, SPS-510). But you better keep them from contact with water and avoid moisture from getting inside the speakers if you want them to live long.
