BOSS Audio Systems MC420B 3 Inch Motorcycle Speakers and Amplifier Audio Sound System – Class D Compact Amplifier, Weatherproof, Volume Control, ATV UTV Compatible, For Stereo, Tweeters

Quality product! Sound is awesome for a $60 system, at 40mph and lower its great. It's plenty loud enough, but as you approach 60 mph and up truth is no stereo is going to sound like a home audiophile system. Bottom line is 'buy it'!Customer service is first rate, they are great! Also, I read some complaints about bass. When I first connected the speakers they too sounded a bit flat. I clicked onto my Poweramp music player and set it to large concert hall and max bass and presto... truly impressive rich sound!My install - I mounted the speakers on the handlebars just inside the windshield. Then, ran all the wires and the amp into a small, front fork mounted, 'tool bag' type pouch. The main issue is the red hot wire. I must have watched a dozen youtube videos on this subject. I usually ride with my high beam on. I know its obnoxious, but down here in Florida anything you can do to stay visible is a life saver. I unscrewed the chrome cover that holds the daymaker headlight in place. Sadly, Harley does not provide an auxiliary wire in the headlight wiring harness of Sportster's. At least not in mine. There are three wires entering the headlight assembly from a hole in the back. Black wire is ground, white wire is High Beam, yellow wire is Low Beam. I used a plastic splice connector from Home Depot to connect the red Boss power wire to the white High Beam wire. (AMP Splice Tap Connectors 10 pack).The hole in the back of the headlight assembly where Harley runs the headlight wires - Harley runs the wire harness though the hole with a rubber bushing that protects the wires and keeps water from getting in. I tried to slice the rubber bushing so that I could add the Boss red hotwire but it was cramped quarters and I couldnt get in there without taking the chance of cutting the headlight wires also. You may be able to do it, I couldn't. I ran the red power wire through the hole and at the point where it touched the metal headlight housing I covered the wire with an extra couple of layers of electrical tape to protect it from the housing wearing through the insulation and shorting the amp. Then, pushed the rubber bushing back into the hole. It wasn't a perfect fit, there was a slight gap because of the red wire I installed. It also wasn't a terrible fit - and then I put the headlight and headlight retainer back into place. After continual testing at every stage, and when I was sure all worked as it should, I used a dab of black silicone caulk and filled in the gap between the rubber bushing and the outside of the headlight assembly. This also helped hold the red power wire in place and reduce any chance of shorting against the headlight casing. I ran the ground wire outside the headlight housing for a few inches to a windshield mounting bolt and tightened it down. (I didn't want the ground wire taking up space going through the headlight hole, so I split the red power wire and the ground wire before the power wire entered the headlight housing hole. You may find it works just fine running both wires through, especially after using caulk to close up the hole where the wires enter.) Finally, I used zip ties to connect the volume button to the left side windshield mount, very close to where my hand naturally fits onto the handlebar grip. I believe you want the volume control where your left hand can safely get to it without too much reaching.Final result is my Boss audio system works only when the high beam is on. And when the bike is turned off there is no chance of the amp staying on and draining the battery. Also, my install required no drilling, no running wires under gas tanks and seats, and no toggle switch. I love having music now!!! Safe riding!

Finally a stereo i can hear over my life saving loud mufflers

Bought these for those slow relaxing cruising days.Sound is good, could do with more base.Easy setup and connects to my phone without issues every time.

I have bought several Boss Audio products and have always been satisfied with the quality and performance of Boss.

Easy installation and super loud love em

This system provides mediocre high/midrange sound for a "low budget" system. The amp certainly provides loud volume, the biggest downfall of this system is all the wiring is far too short unless you are mounting the amplifier on the handlebars or within a couple feet of it. In order to mount the amplifier behind the side cover of my VTX1800R/3 I had to cut and splice an additional three feet of 16ga speaker wire to each speaker (the amp has proprietary speaker plugs) and three feet of six-conductor 22ga wire into the hard-wired remote volume control wire so I could mount them to the handlebars.The amp features a 3.5mm auxiliary input cable hard-wired to the unit with the same "way too short" length, making it unusable if you mount your phone/iPod/audio device on the handlebars unless you use an extension cable. Why Boss Audio couldn't just put a 3.5mm female input jack on the unit so the user can plug their own correct length of 3.5mm male to 3.5mm cable into it is a mystery to me. Another negative is the unit does not feature a remote power wire, so if you wire the power direct to the battery it will always be on, draining your battery. To avoid this I had to add a 12v/30a relay with which I could run a remote power wire to the fuse box, allowing the unit to power on when the ignition is turned on. Once I spent a few hours splicing wires, running the speaker and remote volume wires, installing and mounting a relay and mounting the unit inside the tool box behind the left side cover (I drilled a series of 3/8' holes in the box to provide ventilation and cooling as the amp does get quite warm), I was able to power it up and take a test ride. As stated above the amp provides loud audio and could be heard at 70mph behind a 22" windscreen. While the audio quality with music is mediocre at best, the system sounded great when streaming news or other talk radio via the SiriusXM app on my iPhone. A big plus is that the bluetooth connection is great. Once initially paired it reconnects immediately upon powering up the system.The chrome speaker housings are nice looking as long as you don't let them touch anything... be very careful not to let them rub against anything when installing as the chromed plastic will scratch/mar VERY easily.If you're 1) looking for a low-priced system for your motorcycle and 2) you're not afraid to cut/extend the wiring to make the system usable and 3) you have several hours to run wiring and 4) you're not an audiophile who demands anything more than highs and midrange, then this system is for you.BOSS AUDIO MC420B Chrome 600 watt Motorcycle/ATV Sound System with Bluetooth Audio Streaming, One Pair of 3 inch Weather Proof Speakers, Aux Input and Volume Control
