hey i found a kit for $199.00 that has 4 light bars (2 4' and 2 3' sections) that are supposed to be used under the body, but I thought of instead using them inside mounted clean and out of the way somehow. they change colors and or show only one color depending on your setting. just wondering if there is a kit out there that will react to sound? Like react to the music your playing in your system? thanks...
