BOSS Audio Systems ASK904B.64 Marine Bluetooth 6.5in Speakers & Amplifier

So far so good! Installed on 5/25/26. Sounds great. Straight forward install because all the wires in the harness are well labelled. Easy to connect my phone via Bluetooth. We will see how it holds up throughout the boating season.

After evaluating many options on the market, I bought this amplifier, read many reviews, and compare different options. I chose this one because it already had the speakers included. It is not easy to choose the right speaker for an amplifier since the amplifiers have RMS and nominal power, which changes if the speaker is 4 or 8. It is not easy to choose the right speaker, so I thought it was very good that already the amplifier will bring the speakers. Less task to acquire the whole set. I was surprised by the size of the amp. It is really small. I thought the sound would not be that good, but I was wrong. The sound surprised me! It is very good! My boat is a 21-foot bowrider type and with the engine running the old audio system just couldn't be heard, so I decided to change it for a better system, and this one works well. Pros: - The small size of the amp really makes it easy to hide it inside the boat - Bluetooth connection is extremely easy - The controls screen facilitates everything - It is a totally marine product - The speakers are easy to install and have the patterns to make the holes. - The USB connector is very good. Read MP3. - It is a very practical system and the sound is very good. Now my friends call it "the party boat" :) - the price is right. Cons - I don't have any for now.

A high-quality, precision item—in addition to its robust construction. 100% recommended.

I purchased this on the strength of the reviews I read, looking for a stereo system for my refurbished pontoon boat. Easy to install; the manual is straightforward and also can be downloaded from this site, which I have done as I have had to refer to it. However, much to my dismay, with my 30-year two-stroke Mercury and a single battery powering my boat, the stereo would work great with the engine off, but when I turned the engine on it would cut in and out. Not acceptable. I came back and looked again at the reviews and found some with the same problem, which I must have overlooked initially. I thought this stereo system was a lost cause after reading those reviews and that I would have to replace and be out the money. However, in the refurbishment of my used, 30 year old boat, I added a second battery and a new 4-stroke Mercury 75, and the stereo works great, as it is supposed to. No cutting out. I wonder if the electrical source from the old engine was not as powerful as the new engine's alternator, or if perhaps having two batteries available when the engine is on gave more sustainable power, or perhaps both or maybe there is another reason. So my 1 rating because it did not work has turned to a 4. I can't give it 4 because there is no mention by the manufacturer that there could be a problem, nor what causes the problem or how to fix it. I also installed a new custom-built console, and the stereo's controller is installed above the steering wheel. That is also where I mounted the USB-1/4" input jack. I am very happy now that it is all installed and works properly.

Well, you need to be fairly "handy" to install and fully enjoy this baby. Amazing sound once you get everything all hooked up correctly. I ran my power to a completely separate battery in the hopes of eliminating all the interference when the boat is running. So far, I haven't figured that out. When the motor is not running and I'm running this unit from the separate battery it kicks butt! The secret is to mount your speakers where you take full advantage of the bass vibration through the fiberglass body of your boat. I bought the four speaker version and it knocks my socks off although it's just a 16 foot bowrider. Overall very happy with this unit and the sound. I think the unit cutting out has nothing to do with this unit or the quality, it's just a wiring issue that seems to be very common on all boats. I will say this though: the key is to get a very solid ground. I did not have great success or great sound until I went straight to the auxiliary battery. Now it rocks. I've had no issues with the Bluetooth connecting other than normal Bluetooth issues. Keep it fairly close and it picks it up perfectly. I highly recommend this unit. I think my only issues are user error in getting the unit to perform at the same time that my engine is running.

Installed in my new 2025 Avid Rogue 20. Install was SUPER easy. I watched like 3 videos and felt like i had the jist of it. Mounted to the center console and it's pretty loud. I have a yamaha 150 and even WOT the music is easily audible. For the price, this is it. IF you're an audiophile, or looking for a better bass response, you're gonna have to add a sub and amp.

Does not work in a boat with a 2 stroke engine. The stater interferes with the bluetooth receiver. We tried a register and a filter. Neither will work. I later found this information to be confirmed by others experience. Had i known i would not have wasted my time and money on the purchase and install.

I was a little nervous based off of some of the reviews but man this thing sounds so good! we did order some bass speakers so we can have more base but they put out a surprisingly loud sound which is perfect for our boat and even without the subwoofers it still sounds pretty dang good ! Very impressed and easy to install! Haven’t had it long enough to know if is truly water resistant time will tell so I still have that a 5

Sounds really good for the price

El producto esta fallando ¿Que debo hacer? Falla: Sube o Baja el volumen a extremos, reproduciendo MP3, en ocasiones sube el volumen al maximo de forma autonoma, sin mando del celular, y los controles del aparato no responden; lo mismo hace pero en sentido opuesto, baja el volumen al minimo (0), sin respondeer. ¿Como pueden ayudarme para resolver esta situacion?

me fue de mucha utilidad, lo único es que si piensan agregar mas bocinas nos les servirá el amplificador ni el bluetooth. pero suenan muy bien.

Good sound, easy installation.

Ordered this not knowing what to expect for the low price. It delivered big, works awesome and sounds great on my 20' jet boat.
