does anyone have a zapco or a hifonics amp, and if you do how would you rate them???? i have a zapco right now, it is a d class amp, and it is the shit, but i am looking to buy a bigger one cause i want new speakers, and i came across a hi fonics 1000 watt d class amp for 300 bucks. would anyone that knows what they are talking about tell me what's up?
