Review on Mini Bluetooth Amplifier For Home, Auto, Motorcycle, And DIY Projects - 2-Channel, 2 X 20 Watt With IR Remote, USB MP3, Handlebar Mounted Control, And 12V Power Supply - Kinter A7BT by Dino Burks

For $15, this thing is simple to work and easy to set up! I was looking for a simple Bluetooth setup for my '72 VW Bug and stumbled upon this beautiful piece of microscopic tech. It doesn't match the sound quality of the Retrosound stereos but if you're not trying to blow the bolts loose in your car and just need some music in the car, this will do the trick.I installed this by cutting the cord from the power supply and stripped it so the black and red wires were exposed. Red is for power and black is ground. I connected the power to my cigarette lighter and grounded the black wire to the body. I'm only running one 25w 4ohm speaker but seems to fill it with sound just fine. If you don't mess up like I did, this thing can be installed in 10 minutes. The amplifier will give you an audible tone when it powers on and when your BT connects. You really can't ask for anything better for the price. 10/10 Would recommend to a friend.
