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: Will be buying these again! - 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! ## Features - Bluetooth - Use your smartphone or MP3 player and get access to a vast library of your favorite music, plus plug into apps like Spotify and Pandora, wirelessly. The 3.5 mm Aux input is also compatible with the audio out of your devices. - Weatherproof - The MCBK425BA has been outfitted with the latest weatherproofing techniques for protection against the elements. Rain or snow, take your music wherever you go - Amplified - The great thing here is that the amplifier is built right into the speakers. This allows for less of a hassle and shorter times for the installation. - Speakers - The two 3-inch matte black full range speakers have adjustable brackets that will fit handlebars ranging from .75” to 1.5” - Auxiliary In – A 3.5 mm Aux-in is compatible with the audio output from smartphones as well as MP3 players.

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! ### ⭐⭐⭐⭐⭐ Honda Vt750 *by J***Y on March 14, 2025* 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. ## Frequently Bought Together - BOSS Audio Systems MCBK425BA 3 Inch Motorcycle Speakers – Built-in Bluetooth Amplifier, Weatherproof, Volume Control, ATV UTV Compatible - JOYROOM Motorcycle Phone Mount, [1s Auto Lock][100mph Military Anti-Shake] Bike Phone Holder for Bicycle, [10s Quick Install] Handlebar Phone Mount, Compatible with iPhone, Samsung, All Cell Phone - EXTRACTME Motorcycle USB Charger, 6.8A Quick Charge 3.0 Dual USB Motorcycle Phone Charger with Voltmeter & ON/Off Switch, Waterproof Quick Disconnect SAE to USB Adapter for Phone, Tablet, GPS --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/83406003-boss-audio-systems-mcbk425ba-3-inch-motorcycle-speakers-built-in](https://www.desertcart.hr/products/83406003-boss-audio-systems-mcbk425ba-3-inch-motorcycle-speakers-built-in) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-19*
