putting this out there as a feeler because I really want a Polk PA500.4 to complete the Polk exclusive system. I have a near mint TMA (Total Mobile Audio) 4 channel amp up for sale or possibly a partial trade. I have the original box and paperwork, it was new when I installed it about 2 months ago. It does 60x4 at 4 ohms or 80x4 at 2 ohms. It also will do 160x2 at 4 ohms bridged. I have this running my MM speakers and it does awesome but I just want the full Polk setup(plus the extra power from the Polk amp would be nice too) Asking $120 OBO. I'll post pics later.
