The bass is not booming but for the size its nice loud doesn't distortion at high volume and its crystal clear. the light show is fantastic I'm looking at the colors change to the sound of the music. I didn't know it had an sd card slot. I put my 32gb car in and its none stop commercial free music 12 outta 10 stars.
