Only have a few minutes of experience with it so time will tell how it really holds up. It’s really small, mounted it on top of one of my 6x9 boxes. But the Bluetooth is effortless and so far the amp pushes the speakers good. Sounds good to me. Installed this behind the seat of my 1951 Chevy truck.

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!

I bought this amplifier because i wanted to play music but did not want a complete radio system as car is build for street and strip. This Bluetooth amp was what i needed. i installed a radio delete plate in the factory location as this is where i will mount accessory switches (electric fans and fuel pump) and start button. This unit is small enough to hide anywhere under the dash or in glove box. The sound is excellent for its size. I have it hooked up to a pair of 6.5" Rockford Forsgate P1650 speakers for the rear and the center dash speaker is the Retro Sounds dual voice cone speaker and all sounds very well - loud enough too. i play music from my iPhone. What i wish it had was an app to allow adjustments to front and rear or left to right but it truly isn't necessary as it sounds fine the way it is. What i also wish it had was a built in mic so i could answer calls and hear calls over the car speakers. For the money spent and to have very good sound in the car, this was a great option. Now, i hope it lasts. follow the instructions to the letter and make sure you have a good ground. When wiring speakers it is important to wire them correctly + / - terminals must be correct. take your time.

Had this installed in a golf cart and after a few months, it failed and wouldn't pair to anything. I'm a software/hardware expert and did every possible bluetooth reset according to the instructions, disconnected power for hours, you name it...bought another and swapped out and it worked.Seems like a shoddy bluetooth implementation.

Nice modern replacement for an old AM/Fm tape deck in my 1986 Harley Davidson.Fit in easily where the tape deck was originally installed with a little bit of creativity.I have it connected to a couple of Hogtunes speakers and I’m happy with how it sounds.Easily connect to my iPhone with Bluetooth and also keeps it charged with usb connection.
