BOSS Audio Systems MC420B Motorcycle Speaker System MC475BA

Great sound and very easy to install. I put two on my handlebars and one on each side of my engine guard.

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.

Llegaron súper rápido, súper potentes y excelente diseño me encantaron

Segunda ocasión que compro esta marca, anteriormente tenia la configuración de dos bocinas esperando que la potencia de estas fuera significativa, pero no, suenan bien y mejor que muchas pero no es demaciado la potencia. el amplificador integrado en bocina es algo genial, montados en una boulevard M50 (sin fairing) son audibles hasta aprox 100 km.

Installation was pretty straight forward, didn't ever even open the manual. However, it took me about 4 hours with bike tear-down and cable management included. I removed the old 2-speaker system with amp to replace with this one. I mentioned cable management because there are SO MANY wires to manage. I will likely go back and cut/splice wires to remove the baseball sized nest I have now zip tied to my frame. Also switch placement was challenging. Finally, after install and road test, I am happy with the sound, but nor sure the 4-speaker system is any louder that the 2-speaker system.
