If you are looking for some really good thumping bass, these aren't the speakers for you. If you want clear-sounding music that is loud enough to hear over the wind and your engine, these are for you. They are hard to beat for the price. If I'm going to nitpick, there is a lot of cable to deal with. But, again, the price was really good compared to everything else. Would I buy them again? Yes.

Can't beat it for the price had em on for a year no issues at all love em.. only concern is you probably could not hear them going full speed IF you have straight pipes, that needs to be taken into consideration.

Nice, easy install. A lot of extra cord for a rebel. Had read sometime saying they didnt have enough length for their harley softail but that would honestly surprise me. Biggest criticism is like no bass but I'd seen other reviews saying the same. Nice and loud to cut through the wind at higher speeds. The 1st one I bought had a defective Amp or dial because when you turned the knob, it did turn on but as you kept turning the knob, the volume did not increase as it should. Called Boss and they were willing to just send the left speaker replacement (w/ the internal Amp and dial attached) however after further looking into it, they supposedly didn't have any left ones in their warehouse anymore so not sure if that means it's a common defect or not. Anywho... I got an entire replacement set and it works fine. You get what you pay for though as far as no bass. Otherwise nice enough.

Good price, works great, nice and loud. A little difficult to install alone but with an extra set of hands we got it done. Definitely recommend and actually bought another set.

Great little speakers pretty good even on the hwy. No bass but your on a motorcycle who cares. If I want to hear perfect sound I can at home. For the price you can’t go wrong.

Empezó a fallar las bocinas, no suena como lo hizo hace unos días. Perdió potencia de volúmen y tiene altas y bajas solo, anda fallando. Solicito garantía del artículo

EDIT 5/19/23:Over a year later and these are still functioning exactly the same as when I installed them. The sound and volume remain the same, as well as the speed of connecting to my phone. All wiring and physical connections are good. No issues. Still 5 stars for me.ORIGINAL REVIEW 4/22/23:I'm not sure if other reviewers received a different unit, but the one I got is great. The one I received had an inline fuse and power switch, and seems to be robust, although I've only riden with them for two days, so time will tell and I'll update this review if anything changes. The installation is very simple, and I was glad to see that the speakers fit on my risers and nested pretty well in the speedo and tach humps in my t sport fairing on my fx softail. Like I said, I'm not sure if other reviewers received a different unit, but this one is plenty loud at 70mph with my 96in motor and short shots. In fact I don't need to turn it up all the way to clearly hear it, maybe 75%. The sound is fairly flat eq wise, and at lower speeds it has okay bass, but the limiting factor is the size of the cones. But here's the thing, when riding a bike, your ear has trouble hearing bass frequencies anyway, and the loudest sounds will be mid-high. It's not that the unit is bright on the top end rather that the signature is flat, and higher frequencies can be piercing at high volume depending on the track, but I don't find it fatiguing if the volume is adjusted accordingly. I think these speakers are a good value for the cost and sound, I'm happy with my purchase, and I'm glad I bought these over the cheaper options.

Installation:Yeah, there are basically almost no instructions -- nothing but a picture, but you won't need more than that if you can put up Christmas lights. Took me 2 hours while talking on the phone and getting distracted a couple times. Hardest part is deciding where you're going to place the speakers and zip tie the wires, which is really a preference thing. ON THAT NOTE, kuddos for a fellow reviewer for posting their idea of clamping the speakers to the engine guard instead of the handlebars. Shyte looks tiiiiiiight. Way better placement in my opinion.Tip on installation -- buy some extra zip ties if you don't have them already. This only comes with 5. The answer to the question "Did I use enough zip ties?" is always "One more." Also take your time with planning the placement of the extra wiring. It'll be worth it.Sound:Other reviews about no bass = truth, but honestly I don't feel like I'm missing out. I've felt more like Ralphie with a new red rider bb gun on Christmas. (Have NOT shot my eye out.) I've heard of some people getting a kicker to pick up the slack, but I'm good. Volume does the trick. Not sure how much bass I'd hear over the bass of my bike anyway. Can def hear over the engine and if you need more volume than this provides, f**k off mate, you annoy all of us. When I get into my neighborhood I drop to about 10% volume and can hear it just fine. Only downside I'll give it, and it's a picky one, is that it's SLIGHTLY distorted at full volume, but you can't tell unless your engine is killed.Looks:They may not feel like much (chrome looks good but on a lot of components are plastic - this is one of them), but they look great. I was afraid they'd make my bike look clunky or cheap or silly -- nope -- looks friggin dope.Longevity:I dunno, I just installed yesterday, get off me. I'll come back if they crap out.Overall:If I had a second bike I'd reorder. They're cheap enough to where I know when I sell my bike with them on there, I'll get the money back or more after a year or two of use, so in that sense, I'm betting they end up free for me. Do it, Doug.
