From add
"This amp is rated at 800 watts RMS by Cadence, but it is really 1,300 watts RMS. We tested this side by side with a Hifonics 1600w amp, and this amp sounded way better, and it was just as loud. "

i just found them. thought i'd get an opinion on em :)

I have a cadence amp they are well built

depends on how much power you need.

i'd go with phoenix gold.

I don't NEED a specific amount. I'm building a new system and those are roughly the watts I'm aiming for anything 500 and up. preferably higher but good quality. Thanks Father Yuli, il take that into consideration :)
