naaah none really, i had a lip kit but i gave it away, i have 2 12' Audio Lightning ( not that popular but i gurantee you these things beat the block down) 2 punch 12's, one is blown and one is fine....to be honest, the Audio lightning beat harder then my Punch's even when i have 600 watt amps hooked up to each speaker and i only had a sony xplod amp, 760 watt 2 channel on the Audio Lightnings...what were you lookin for in regards to your EG?
