I have a memphis mca-2004 and 15-msync6. The amp works flawless and I think has one small scratch. The comp set looks mint but some how my bro in law manage to screw up one of the 6.5's. It doesnt scratch or grind......or work. Nothing shows up on a meter but the other 6.5 and both tweets work flawless. I have pics of both I can email ya. I also posted a blackjack II in the misc classifieds.
