according to some repair people that have posted about them on here they make power well but the build quality is definately questionable.
not my opinion just what reputable people have said openly..
how?? i paid 197 for the 1800their are obviously better amps out there but not for anything close to that price lol
if I trusted them more I would even use them myself. I can get them for 127 shipped each for the 1500's and 197 shipped for the 3k's
