## Description

BOSS Audio Systems MCBK425BA 3 Inch Motorcycle Speakers – Built-in Bluetooth Amplifier, Weatherproof, Volume Control, ATV UTV Compatible

Review: Good system for a good price - 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.
Review: Honda Vt750 - My bike isn't loud. The speakers are pretty loud. I can hear them going higher speeds. It does lack bass but maybe I can adjust that with an app on my phone. I just wanted some music more than anything, but other than the bass, the sound quality is good. I listen to all kinds of music genres as well. Install was easy. I ran the wires under the tank and hooked them to the battery. I also ran LED lights to my battery prior, and it's no problem at all. For the price especially, they're great. Edit: It's June 2026 and they're about toast. For at least 6 months, I've been having to mess with the wires like you do when it's time to replace them. It's about toast, and I'm probably gonna try another brand this time. Idk if that's good or bad. I'm just saying.

### ⭐⭐⭐⭐⭐ Will be buying these again!
*by L***Y on June 24, 2025*

They sound great and have a good connection for Bluetooth. I can hear them inside our house when my husband plays them outside and it’s pretty clear even in the house! There is plenty of cord length for hookup. They are on my husbands motorcycle and he wants some for our fourwheeler as well. They work great and are nice looking while feeling well made. These are nice, durable speakers for a good price!
