BOSS Audio Systems ASK904B.64 Marine Boat 6.5 inch Speakers and 4 Channel Amplifier - 500 High Output, Bluetooth Remote, USB and Auxiliary, Waterproof Pouch

The media could not be loaded. 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.

When brainstorming to add a stereo to my Yamaha Waveventure PWC, I came across this system and it seemed to fit my needs and the size of where I intended to put it. I wanted a way to listen to some music when floating or beached and didn't want to permanently modify my ski. So I installed this complete system in a spare front storage compartment. I'm also adding 2 3.5" speakers into a set of spare mirror housings.The system itself is small, light, and came with everything and seems to be well made, I'll update after use for some time and see how it holds up. For the price, I don't expect it to last forever.I tested it hooked to a YB14 series battery which is smaller than the one in my ski. I didn't hook up an ammeter, but this seems to draw very little power. I ran it on the bench via Bluetooth from my phone for 3 hours. Battery still showed 12.7 volts and charger said battery was still 95% capacity after the test. Battery drain being a concern, I'm very happy with this.The included speakers sound good. Not great, but as expected or better. For my needs, quite acceptable. The controls are easy to use. Blue tooth range is great. I tried it at up to 40 ft away and it worked fine.I'm pleased so far and have no complaints.Update 7/18/2017:One year later, still going strong and works as well as the day it was installed!Update 5/10/2018Almost 2 years later and still works as well as it did when new. And it lives a rough wet life in the front of my Waverunner. It has been moved to my 98 XL1200 which uses the same front storage tub and gets a lot of looks, listens and thumbs up for having a stereo in my ski. I also put the small Polk audio 3.5” speakers I had in the mirrors of my wave venture in the mounting plate. Still love this setup!Update: 10/25/2018Still working like New after another season in the ski. And in the off season I use it in my shop for a stereo. Still very happy!Update: 4/12/2019Still going.............All winter in my shop. And now back in the ski for another season on the water. Still works perfectly!Update 7/29/2019You guessed it.........still working perfectly.

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.

Great product for the money! Connect everything, turn it on, and great sound! Hope it holds up.

I thought buying the all in one kit for the boat would be an easier route. Unfortunately it's by far the worst sounding system I've ever spent the time to install. The second I opened the box I could tell by the tiny speaker wires included. All in all, it's better then no stereo at all. No way id buy this again.
