    • This is perfect!
Color: 4.1 CH With Subwoofer (No FM)
I had this as a replacement idea because another one (pyle marine BT one) ended up not working at all. This one is great! Good bass and the Bluetooth is really cool! Ultimately I realized I wanted to add a mixer for a few karaoke microphones and added a separate Bluetooth transmitter in the mix too. So now I have 3 microphones and a tablet input through the mixer to the transmitter, received to this unit which pushes 2 channel stereo to a pair of great 5way 6x9s and a 12 inch sub. It fills the party bus perfectly. No window shaking, no cracking or hissing. ... show more

    • Powerful and compact
Color: 4.1 CH With Subwoofer (No FM)
I use this to run our 4 built in speakers over 2 floors. Overall great and easy to use with Bluetooth. The only real issue is the bass control knob does nothing. I've got it connected to my subwoofer, but the bass is so strong coming I have to adjust the subwoofer to just barely on. The subwoofer has no issues when previously connected to a full home theater amp. ... show more

    • Great for general use, not for audiophile
Color: 4.0 CH (With FM)
I may be a bit of an old timer... back in the days when a stereo consisted of $100's -$1000's of dollars worth of electronic devices followed by the 4ft tall speakers. So when I first ordered it, I was a bit skeptical on how it would work and the sound quality. However to be able and get the majority of the electronics now in one $40 stereo/amp was worth trying it. The input for a mic could care less about, but this little thing can push some power, amps, watts for different speakers that range in different ohm's. It can't handle my speakers that require higher power but still.. for $40 absolutely amazes me what it can do. I was not looking for one for tv surround, but something for garage. Worked out perfectly. ... show more

The media could not be loaded. The packaging was good although it looked like the box had been previously opened. So far I love the unit! I am not quite sure how well it will hold up under my new shelter being outside in the heat and cold but it is in the dry. I guess time will tell. The unit was easy to setup and easy to hookup. So far I have a set of 4 Herdio 800 Watts 6.5 inches outdoor speakers I also bought from Amazon. I hooked them up and they sound great. It has an FM transmitter built in but the unit did not come with a FM antenna so I am going to have to order one so I can listen to FM radio stations clearly with no static.. The Bluetooth connects quick has good range and stays connected. ... show more

    • Cheap and does the job
Color: 4.1 CH With Subwoofer (No FM)
First off, if you're an audiophile, this ain't the amp you're looking for. It's quite obviously a Class D unit, and only does mono audio via Bluetooth. BUT, if you've got a few speakers lying around and you want some sound, it does the job. It's tiny and can be hidden almost anywhere. It's especially good if you're setting up your back yard, or any other large area. Since there's no stereo output, you won't lose any panned audio in any of the speakers. It'll be the same exact sound output from all 4. Some notes: it seems like the bass and treble knobs are additive. Meaning there doesn't seem to be a way to bring the mids up. It could be my hand me down speakers being really bright, but they sounded decently flat when connected to an old school receiver. Also, the two volume knobs for the pairs of outputs are a different levels (12 o'clock and 2 o'clock) and the speakers sound like they're all at roughly the same volume. I had to get my roommate's opinion to confirm that I'm not insane, and he agrees that it all sounds centered. Could still be the craptastic speakers if somehow they're not the same impedance. They're old, but all the same model. Pretty sure that wouldn't be the issue. ... show more

    • Great size
Color: 4.0 CH (With FM)
This aplifyer was smaller than I thought it would be. It fits great in the small cabinet I had for it. It works great with the old wired speakers that were in my home when I moved in. The previous owner had not been able to work the speakers in 3 years cause they could not locate the right amplifier. This amplifier's Bluetooth compatible was a perfect addition to this older style home. Easy to install and Bluetooth easily discoverable on devices. ... show more
