Thought I needed these amps to fix an audio problem I was having, but it turns out my amps were fine. Asking $60+ship for the 2. I pulled these Infinity speakers out of my car. They are Infinity Kappa 682.7cf. These won't work with the Mach 460 because they'll burn up the amps, but could be used for other applications. Looks like crutchfield used to sell them for $90 for a set of 2. So I think $60+ship for the 4 sounds fair.
