Questions & Answers

Are these weather-resistant and suitable for use on a motorcycle?

Yes, the marine certification is ideal for motorcycles, as it ensures that they will perform well in wet environments. In my boat, they sound fantastic as well!

What is the maximum output of these speakers?

Good day, Floyd, and thank you for contacting us! I double-checked these speakers on our website and discovered the following in terms of power: handles up to 100 watts RMS (300 watts peak power) and has a frequency range of 10 kHz to 20 kHz. 55- sensitivity: 22,000 Hz, frequency: 22,000 Hz Impedance - 91 dB, 91 dB, Ohms: I hope you find this information useful, and please let us know if there is anything else we can do for you!

Is it compatible with 2008 flhtcu ultra classic rear and front speakers?

They fit perfectly on my 2008 Ultra Classic Harley, are waterproof, and have a great sound. These are an excellent choice if you simply want to replace your stock speakers. br>Instead of replacing the front batwing, upgrade to a speaker kit that will allow you to use a larger 6. (waterproof) 5 marine speakers Easy to install, and for someone like me who doesn't want 300 watt amps or to change wiring, the upgrade from stock is fantastic. Ride on !

What is the outside cover's size? My existing speakers have a 6" cover on them. ?

Selected User Reviews For Polk Audio DB522 DB+ Series 5.25" Coaxial Speakers with Marine Certification, Black

Range and performance are fantastic! These were purchased as a direct replacement for the ones that came with my 2018 Coleman Travel Trailer
5/5

Most RV audio components are subpar, but these Polk speakers brought them to life! We've had some pretty bad storms and snow this winter, and the speakers are still working perfectly. I strongly advise you to purchase them.

On my motorcycle, this is exactly the sound I was looking for
5/5

These speakers have a great sound! These speakers, along with my new Slipstreamer windshield from Amazon, are providing me with the sound I was hoping to hear when I purchased my bike; unfortunately, the stock speakers on the Vaquero are CHEAP! At 75 mph on the highway, these speakers sounded fantastic and I could clearly hear my music!.

TJ Wrangler Front and Rear Speaker Replacement For TJ Wranglers, factory replacement speakers are available at a low cost
5/5

In my 2005 Jeep Wrangler Unlimited (LJ), it's been installed. No sound bar modifications are required because the rear speakers fit neatly within the sound bar. Front dash speakers are installed with an extra bracket that must be purchased separately. You can install the supplied wires and connectors by cutting into your factory speaker wires, but I recommend purchasing additional wire connectors/adapters to ensure a clean speaker plug-in. The factory speaker wire harness is preserved during installation. With the factory stereo, the speaker loudness and output are adequate; an amplifier is not required. These speakers are also waterproof, which is important for Jeep Wranglers.

Outstanding communicators
5/5

On my Harley, it sounds great. 2009 is a vintage year. Mids and lows are particularly strong. I'm going to order two more for the Fairing speakers.

The ideal accessory for Harley-Davidson motorcycles
5/5

These were ordered to replace the speakers on a 2003 Harley-Davidson Electra-Glide. I've gone through three pairs of "harley direct replacements" so far. "These are far superior in quality and fit perfectly. Compared to the original "oem" speakers, these speakers are significantly louder. It comes highly recommended!.

The Travel Trailer has received a significant upgrade
5/5

On my travel trailer, I needed to replace the outdoor speakers. I couldn't be more pleased. The audio quality is excellent. The bass is adequate (in fact, it's quite good for such a small package). We listen to these at a lower volume at our campsite and are very pleased with the sound quality.

As if it were night and day! Get them! These speakers were purchased as a replacement for the factory speakers, which were lacking
5/5

We set up a projector screen for movie night camping in the quiet woods with family using the old speaker setup, but the audio was difficult to understand and hear even in front of the speakers, causing the kids to lose interest, which was not fun. br>However, with these new speakers, the audio was crisp and clear, and we could actually understand what was being said; we listened to audio books and the difference was night and day. We still need to upgrade the speakers on the inside, as they have the same problems as the old speakers on the outside. It could be extremely quiet with the speaker volume turned up, and I could sit right next to the speaker and not understand a word being said, which is extremely frustrating! We simply turned off the inside audio and turned up the new speaker audio, and we were able to hear and understand the audio words from outside much better. br>As a result, I strongly recommend these speakers! Go for it! They'll make you so much happier than the stock speakers' blurry, terrible audio. br>It took my husband about an hour to install it, but he was working on other things at the time. So there's a chance it'll take a little less time to set up.

Speakers who are excellent
4/5

Outstanding communicators. The treble and midrange are fantastic. On the bass, things aren't looking so good. The treble appears to be a ten, the mid-range is a ten, and the bass appears to be a five. Nonetheless, it was a wise investment. When I turn it up to 25, you can tell the difference between it and factory. On my motorcycle, it was very simple to install. I didn't use an amplifier when I put it together. PROS: br>br> As you increase the volume, the sound becomes louder (factory speakers appear to reach a limit). br> All of the cymbals and high hats are audible. Not to mention the words themselves. CONS: br>br> There isn't enough bass (there is some, but it's a little low). It's drowned out by the high treble. My 2015 XC's speaker grille did not fit.
