Blown away by the volume!!!
The media could not be loaded. I’m seriously impressed with this BOSS sound system. I installed it on my 2003 GSX-R1000 and wasn’t sure if I could fit four speakers up front, but I managed to get three up there and placed the fourth in the trunk next to my LED controller. Now my lights strobe to the beat—super cool effect.The video I posted shows it playing at the lowest volume setting, and it’s still loud. My bike is straight piped, so I was worried I wouldn’t hear the music while riding but I can hear it clearly over the exhaust even at 60 mph. At 80+ mph, you can still hear it well, especially if you don’t have an extremely loud exhaust.The sound is clean with no distortion at max volume, and the bass hits nicely. I tested it in an open parking lot and could hear it clearly from over 100 feet away. Installation was simple, just connect the power and ground to the battery; the rest is plug-and-play.Bluetooth connects fast, and the volume knob also acts as a power switch. I’ve washed my bike and the speakers held up perfectly—they’re definitely waterproof. I’ve run the system at full volume for over an hour and the amp stayed cool the whole time. The speakers feel solid and durable, and the compact amp (about the size of your palm) is easy to tuck away. Overall, the system looks great and performs even better. Highly recommend this setup won’t disappoint.

Great system works great. Straightforward install
First of all I want to say I am very pleased with this system. The system works well. And is plenty loud enough to hear on the highway. Bass is satisfactory but given that there is no subwoofer there is a limit to the bass. The mounting the speakers is very simple and straightforward. Mounting the amp is trickier since you have to find a safe spot on your bike but then it’s easy too. As far as wiring the system with some basic know how you can do this yourself because paying a shop to do it will get expensive. Think double to triple what the system cost to buy the system.If you are going to install yourself some things to know:First if you want to wire it directly into the battery you will need a rocker on off switch if not you’ll need to know where you can find a wire that is only love when the key is on. I personally wired mine to my headlight wiring at the battery.Second you may need to extend the wires depending on your vehicle’s size I personally added a foot to give me some slack on the wires. This means you may need to buy wiring and tools to link the wires.Third you will want some kind of zip or cable ties to keep the wires running neatly.Fourth you will want to be familiar with your vehicle. I have a Honda Shadow 750 I mounted this on and the best way to wire a bike is following other cables on the bike which means going under the tank. Typically this is simple and it sounds a lot harder than it is.Fifth this is not a tool free install you need a wrench to tighten the speaker nuts and any tools you need to get to your battery and wherever you want run the wires.Last don’t get discouraged. This is not a hard install just don’t expect to just plug in and go this will probably take you a couple hours to do right. But it’s worth it. Also there is a video on YouTube where a guy installs this exact system that may give you an idea

Almost perfect but still very much worth it
Sound Quality: I am loving the speakers. I own a HD Breakout with open pipes, no windshield and up to 70mph I can still hear the music. Of course that the sound quality decreases due to wind noise and when I throttle up but it is expected.Con: The installation brackets cannot be removed unless you detach the connection plug and it can damage the product. The kit should come with at least 3 different bracket sizes and they should be easily released from the wiring.Waterproof: So far no issues with that. Works perfectly.Volume toggle: not the best. Boss should develop a wireless control for the system. I went online and bought one for my phone. Fixed it on the handlebar and it works flawlessly.Installation: they’re fairly easy to install. I’ve managed to fit the amp Underneath the seat and it worked great. You’ll have to check the screw nuts once in a while for they become lose as you ride due to bike vibration. Only the brackets that were a little bit short for the handlebar so the nuts barely touched the screws forcing me to bend the brackets a little bit and I couldn’t use any of the rubber protectors, used a black duct tape.Price: Great speaker for the price. I had a GoHawk Halo before and there’s no comparison between those two. Strongly recommend the poduct.Hope it helps.
