If I do it I'm using OEM HU. I was going to have a nice set up with JBL MS-A1004 amp, Kappa Perfect 6.1 front, and Kappa 63.9i rear. But I had to sell my stuff to get winter set up lol. I'll probably get them again after I get my tax refund since I can get a great discount on them. Might not go with the Perfect 6.1 this time as they have very mixed reviews about the harsh high.
