You are going to need lots of batteries...
For the money I would look at the NVS1 speakers instead of the Skylon.....NVS (www.nvs1.net) will kill those those Skylon speakers hands down and they are only a couple hundred $$'s...same power requirements but bigger and better drivers and horns...just my .02 I have tested both.
The rest of the stuff is nice....but I am not familiar with the Kenwood Amps...
