Ok, I've doing some searching for awhile, and couldn't really find much on the Hifonics amps. I found a few things but they weren't very good reviews, just a guy saying he has and they are good. But are the Hifonics amps any good? because the BRZ1200.1D, the one I was looking at, has similar power ratings has the Audioque 1200D and the Sundown SAX 1200D, but for a good bit less. Are they made with cheap parts?
