[This review was collected as part of a promotion.] I recently installed this Audio System, and I'm impressed with its performance. The installation process was fairly easy, and the compact footprint is a plus. The 4-channel design and 4-ohm stability ensure a robust and reliable output. With features like weather resistance, thermal protection, and zero current draw, it's a solid choice for various applications. Overall, it works great, and I'm satisfied with the performance. I think it's a great brand and durable quality.

[This review was collected as part of a promotion.] Thank you to influenster for sending me such a cool product to try! If it wasn't sent to me then I would've never bought it or discovered how much an amplifier can change sound quality!! I love this product!! Highly recommend to anyone looking for an amplifier! Great product!

[This review was collected as part of a promotion.] I was able to effortlessly connect my Samsung Note 4 Android phone to it and hear all of the audio from my phone: taps on screen, text msg tones, ringtone, Google Maps Voice-guided Nav, Spotify, etc. It will soon be tested with a Windows 8.1 Pro PC with an ASUS BT 400 dongle. If I'm able to update my review at a later time, I will let you all know how that worked out too. With this amp's lack of an built-in equalizer (mentioned as EQ going forward), you will need to have an EQ on the device you're broadcasting audio from (BT, 3.5mm, etc). Android appears to have an equalizer built in (at least on the newer versions, I'm running 5.1.x), however I probably didn't look hard enough to find the user interface where I could control and manipulate the EQ. So I jumped on the Play App Store and found a few options, some free, some paid to remove ads. I initially downloaded "Equalizer FX (Free)" to see if it worked - it did, very nicely too I might add. Please note: you will be prompted to disable the Android's built-in EQ when you initially attempt to enable the Equalizer FX EQ. This is a one-time step. After verifying it basically did what I needed, I paid for the ad-free version - hate ads! The only quirk I've found with the app, which I is associated solely with this particular app, not the amp, is that when streaming audio, with the EQ enabled and adjusted to my liking, and using Google Maps Voice-guided Navigation at the same time, the EQ freaks out and the bass boost is pumped up to what seems like the max. But again, this is an app-specific issue and not related to the amp. Just a tip for my fellow Android users who may be beginning their search on how to get up and running. Overall, I'm very, very happy with my purchase and would recommend it to a friend who was in need of a BT amp!

[This review was collected as part of a promotion.] Boss has always made high quality audio products, and this product is no different! It's weather resistant and marinized for powersports or marine! The illuminated remote makes it even easier to control, with its 20 foot cable. With USB charging and a RCA aux input, this streams your favorite audio and music apps whether on land or sea!

Nearly certain this is just the boss marine "radio" inside an amp case. I should have known when I didn't see any tuning dials or a wire harness in product photos. it's (no tuning) full range on BT and is advertised down to 20hz... got this amp for a customer and I won't even install it after testing it.
