DON'T try to save on power cable, since you are putting in pretty decently powerful equipment. Lower gauge power cable = more voltage drop = lesser voltage at amp = lower power output possibility on peaks. Anyhow the cost of the power cable is one of the least in the equipment complement, especially if one uses branded Indian power cables.

Not much to differentiate between the two amps. Of course the Kicker, being a Class D amp, is the more energy-efficient of the two.

I would take Chiragh advice if the price of Kicker is less than Kenwood mono. The Kenwood mono easliy give 500+ rms at 2 ohms.

well the kicker is i think 20,000 with bill and warranty ,200$ usd from us
Rockford Fosgate is i thinkk 17,500 with bill and warranty 120$ from us
Kenwood i don't know how much it is.

When you say energy efficent how far is it going to matter?
