A dual 4 inch red cathode kit, a dual 4 inch blue cathode kit, two sound activation modules, and shipping, comes to like $50. All I wanted to do was make my subwoofer light up with sound sensitivity >_>. Ah well, it's what we must go through. I'm probably going to buy them from FrozenCPU.com, since they it seems to be the only site I can find that has everything I need. Anyone see this stuff around anywhere for a cheaper price?
