Query: This thing pushes out enough juice to make my stereo sound 10x better. Treble and bass are perfect

Firstly I have a pioneer audio in my vehicle, with a built in amplifier. This thing pushes out enough juice to make my stereo sound 10x better. Treble and bass are perfect, and it plays Bluetooth audio off my phone even if the phone is in the trunk. Additionally the unit looks great. The touch screen is very responsive and the video quality is good. My kids love watching movies during trips and enjoy the sound quality off it. All in all this unit comes at less then half the price of other units and provides great quality to the customer. I am thoroughly satisfied.
