Kinter MA170BT 2-Channel Auto Home Cycle Arcade DIY 2 x 18 W Mini Amplifier Bass Treble RCA Input Audio Mini Bluetooth - Free APP - Amplifier with 12V 3A Power Supply

I got this amp for a makeshift car stereo substitute so I wouldn’t have to disrupt the retro interior of my 1991 Toyota Tercel. The Bluetooth is my primary use-case.The amp came well packaged and, although the device itself is a bit light and cheap feeling, it worked like a charm as soon as I got it wired. I hid it away in the glovebox and it did a great job of delivering decent sound to the cars 2 speakers... for about 2 weeks.Yesterday I was listening to music as normal. I turned the car on this morning and after a brief 7-10 seconds of choppy audio (out of one speaker), the sound stopped coming completely. I checked the connections to and from the amp... all fine. I disconnected and reconnected the amp from my smartphone... all good. The speakers even make a slight whining noise as if a song is about to play... then nothing. Dead silence. The phone recognizes the device and appears to think it is playing audio, but no sound comes through.I wish it had stayed working, but as is I can’t recommend it. Look elsewhere!

I was looking for an amp just to get me through a couple of days while waiting for a receiver. I had these connected to some Micca MB42X bookshelf speakers and it was ok. This amp doesn't have much power to drive those speakers so look elsewhere if you have good speakers. There is some static noise at low volume and it alternates through my speakers. Given the price point, this amp is great since where can you get an amp with a power supply for less than $9?

The concern with these cheap amps is longevity. So all I can say at this point, is so far so good. Look, at the end of the day, your not paying very much for the amp. And for me, it worked as advertised right out of the box. Maybe not the fullest, richest sounding amp, but for the money, it works great for my TV set up in my bedroom. I'll be happy to bump my rating up to 5 stars if it's still working in 3 years. Time will tell.

I bought this for my Arcade1Up Retropie mod. The amp is as described. It's lighter and smaller than I expected, but overall it does the job. I went with this model because it comes with a power adapter whereas the non-bluetooth version required you to source your own. It's slightly more expensive, but when you factor in the cost of a power adapter plus bluetooth functionality, it was worth it. However, the bluetooth functionality isn't that great and it wants you to download a questionable app to control it. I was hoping for the added convenience of BT but I ended up not using that feature.

Meh. Lots of crackles and pops. Wound up ordering a different one with better results. Used in a bar top arcade it had good amplification, but the pops were way too annoying. BT function works, but not very well.

Your browser does not support HTML5 video.  This is perfect for Retropie Arcade I'm building for my son. It's hooked to some Pyle LED speakers sounds great. The BT App is nice because I was able to adjust the bass and treble with it.

It works as good as big receivers but at 1/10 of the price. great for your bedroom and includes Bluetooth , dont forget to get a pair of small nice quality speakers nothing bigger than 6"

Works OK for table top arcade box
