I have 2 10" kicker cvrs. They are dual voice coil and 4 ohms each. I need to know if i should get a mono amp that is 1 ohm stable or run a two channel amp at 2 ohms. I was thinking of gettting the jbl 600.1 amp or the kenwood 7251 amp. Are either of these quality amps or should i look at something else. I want the to get the most power i can get out of these kickers!
