Scott, you continually keep offering me money but it's not enough. However, I do wanna work with ya buddy; you seem like a nice enough guy. How about $76 cash, that 15" HDC and your PPI for this Amp? You (or I, even) could then build your own better 18" or 15" for the M.A. from scratch. The only reason I am selling it is because I presently do not have a Charging System capable of pushing it, really. If you are going to get the most out of this Amp, you are going to need a 200Amp+ Alt, which you have. Take care.
