Im in shock that someone talking about buying aan udison vrx amp is using a COMPRESSED MP3 MUSIC SOURCE! Thats like wiping your behind with 100 dollar bills. Spend your money on a good head unit, twith a 24 bit D/A converter, and throw out the MP3's first. After you are done with that, save up for the Audison VRX, as it is the perfecrt match for Foacl linesou
