I'm getting ready to order new subs and I was thinking trip Fi X10's. Dual 4 ohm vc's. I believe they're rated at 350-400 rms each (I don't have them yet) and I'm debating between the ZX1500.1 or the ZX1000.1....Let's say the 1500.1 is pushing about 1500 rms at 2.67 ohms (safe assumption???), would 500-550 rms per sub be too much. Also...would 500-550 be too much per sub for liek Diamond D310 (they aer dual 2 ohm vc's and are rated at like 400 rms and the ZXs are gonna push about 1600-1700 and 1100-1200 respectively at 2 ohms..
