    • Highly recommend, great purchase
Style: (2) 3" Black Speakers + Class D Amp
So far these have turned out to be a great purchase. Instructions give a very clear guide on installation. Everything being labeled makes it super simple to understand. Connecting to the system is very easy. Speakers are clear and sound great even at highway speeds. Although there is almost no bass, so upbeat songs don’t exactly sound the same. The only minor cons that I could think of so far is that the instructions don’t tell you that you will have to have some kind of wire connector to connect them to your power/ground source. So if you don’t have any, be prepared to make a run for them. The other thing is the rubber pieces that come with this are either really thin or really thick, there is no in between. I had to use the thick ones and a locking plier to get the bottom nut onto the threads and it proved to be slightly challenging. ... show more

    • Easy Install, Good Sound, No Battery Drain
Style: (2) 3" Black Speakers + Class D Amp
The media could not be loaded. Installed on a Can-Am Ryker (stock exhaust) BOSS Audio Systems MCBK420B Bluetooth Speaker System Overall, this is a solid little setup—especially for the price! Installation was super easy. I wired it directly to the battery, and despite what some reviews say, I haven’t had any battery drain issues. The volume knob doubles as the on/off switch—just remember to turn it off when you’re done, and you’re good to go. I’ve tested it like this for several days with no problems. As for sound: you definitely get clear highs and mids, but don’t expect any bass—this is a budget-friendly system after all. Still, it’s way better than riding in silence. I can hear my music clearly at around 40 MPH. And when you’re stopped? It’s almost too loud—my ears were ringing a bit from the volume, haha! ... show more

    • Need to sell some of the parts separately so can buy when break
Style: (2) 3" Black Speakers + Class D Amp
Speakers sound great if the volume knob provided didn’t break I’ve had them on my bike a couple of weeks and had no trouble with them and all of sudden I have no volume when I turn the knob it clicks and sound's like they are connecting to my phone but nothing and then on top of that I can’t turn them off either so they are constantly giving out a bong noise so had to take them off the bike so great sound but waste of money all through the power knob provided is pretty silly and breaks ... show more

    • Great Quality & Even Better Sound!
Style: (2) 3" Black Speakers + Class D Amp
I bought these for my husband's motorcycle-- He installed them last night and we were BOTH blown away at the quality of the sound, the quality of the speakers themselves, and the volume of the music. These are 100% worth every penny!

    • Eh, Not Worth It *EDIT* Meh...Sure.
Style: (2) 3" Black Speakers + Class D Amp
I always wait for a bit before I write a review because I want time to use it. It allows me to be real and fair. This, for the price, seems pretty fantastic. From a looks standpoint, it fits the bill. I have a black motorcycle this is attached to, so the matte black option makes it blend right in. Appearance, it's a 5*. Now, the reason this gets only 2 stars from me is for a couple of reasons. First and foremost, I purchased this about 2 months ago, and already, one of the speakers is blown. I always treat new speakers the same way; I run them a variety of ways to break them in. Well, I guess I did literally break it in. I would have it on with the volume way down low and up high and ranges in between, and about a week or two ago, the right speaker is blown. So, from a quality standpoint, that knocks it down immediately. As stated in other reviews, the sound quality is ok at best. Volume, this thing can get pretty loud. However, it doesn't have a great range of sound, from bass and treble. It just gets loud. Now, you can definitely hear it at highway speeds with a full face helmet. Half shells, brain buckets, whatever you want to call it, you definitely hear, until the wind gets to be a bit much. But what stands out is the lack of quality sound. Installation wise, it really isn't terrible, but it definitely isn't easy. It contains what is needed, but it is bare minimum. I added an additional kill switch so it will cut off with the engine and not stay on all the time. That's more of an annoyance, especially with how motorcycle batteries work. So with all that said, I wouldn't recommend it. It's a cheap price for sure, so I guess if you want an easy starter kit, go for it. However, I feel like I'm already forced to fix/upgrade, so this $60 some odd could've went for something better. EDIT**** I updated it to three stars. I wouldn't say it blows you away by any means. I still don't like that the speaker blew within the first few weeks of having, and I didn't even have it on full volume. That said, it holds up well in rain, and replacing the speaker with an at least decent quality 3" speaker makes it decent. I wouldn't say it's the best ever, but for the price, ease of installation and compatibility, and look, sure. Go for it if this is your budget. ... show more
