Review on BOSS Audio Systems 611UAB - Single Din Multimedia Car Stereo with Bluetooth, Hands-Free Calling, Built-in Microphone, MP3 Player, USB Port, AUX Input, AM/FM Radio by Cory Spence

I bought this to replace a burned out ECU in my wife's car, the simplicity of the interface suits her very well. However, it lacks power at high speaker outputs. Connected directly to the standard speakers and the max volume wasn't very loud. I ordered a basic 200 watt Boss amp and matching 6x9 speakers and it sounds pretty cool for the price. (Paid less than a hundred dollars for the entire installation). The default sound is also pretty flat for my taste, boosted the bass and treble to +2 and turned up the volume, this had a big impact on the sound quality.
