Hifonics makes pretty **** good amps, I installed a Zeus(I think its called) series amp, and it worked really well in the application. Consumer was happy and thats all that counts in the end.
Now you guys are talking about the new kind of hifonics, but the good ones are the old ones, I'm talking the serie 7 and 8 I thinks one of the best amps ever buitl was the zeus serie 7 and 8 rated @ 600 W, 300 X2 @ 4 ohms but they are very underrated, one of these in mono at 4 ohms puts out over 1800 watts, no joke !! I have a colossus runing 4 1200Q in stereo and it pushes them hard,, really hard. 151.8 db if you want to chek it out.. http://www.cardomain.com/id/ambrocio
