seems like a pretty good setup overall. You could use a little more power overall on the subs, but for the price that amp is a good deal.
If you are looking for more power, something around the range of 600-800 rms, check out some of the MA Audio amps. They have several amps that makes alot of power that are fairly affordable. I have had one of their 1800 watt rms amps in my truck for several years after my friend had it for a while. I have used it really hard and never had a single problem with it.
I found this one of ebay. MA Audio HK898. Their HK series of amps are badass.
This one is 2x300 in a 4 ohm load (perfect for your subs) and the amp is going for around $189, a little cheaper than the Kenwood and a better amp.
