Im looking at sub amps to run my single 12" infinity. This one is rated at 400 watts rms in bridged mode into 4 ohms. I can get it for 425 out the door at a local car audio shop. Or about 300 online. prices in canadian funds. Would this be a good amp for the money? any other suggestions?

Whats the subs resistance? 2ohm dual voice coil, 4 ohm dual voice coile, 2 ohm single voice coil?

The amp youre looking at puts out 400 rms or peak at 4 ohms?

my sub is a single 4 ohm, the amp puts out 400 RMS at 4 ohms bridged. An in store bench test says 430rms and 1700 max or something liek that
