Do you always want to use a mono amp for subs, or can you use a 2 or 4 channel. Also which setup would be better. Thanks.

You can use a 1/2 or whatever chanall. A class D or mono, will usually go to a lower ohm load so you can use all of it's power. Ohm's is basically the way you can wire your subs. The lower ohm's your amp can go, the more power it can produce.

For example, say you have a 500 watt amp!
At 1 ohm, the amp will put out all 500 watt's.
At 2 ohm's, it will put out 250 watt's.
And at 4 ohm's, it will only put out around 125 watt's.
Most people buy there sub's, then match up the amp to them.

Each is gitting 200 watt's.
If each sub is wired in paralel, and each sub is gitting a 1 ohm load, and ther is to sub's, that is a 2 ohm load. Your amp should say what the power rating is at 2 ohm's.
You don't always have to git the amp that can go the lowest on ohm's. Take my amp for example!
I have the Rockford P8002.
My sub's can only be wired down to 2 ohm's, and I have 2 sub's. So I had to find an amp that put's out the power I needed at 4 ohm's.
That's why I said most people pick out there subs, then pick out the amp to match them.

would 2 INFINITY KAPPA PERFECT 10.1D and the Infinity Reference 610A 761watts Mono Amplifier be a good match together?
