Here is a few I found from good sellers with good iTrader ratings
Nice mono amp here http://www.canadiancaraudio.com/onli...kages-8-a.html

http://www.canadiancaraudio.com/onli...h-sq-amps.html Mine
http://www.canadiancaraudio.com/onli...9-hate-do.html also mine
There is a few more in there like this

Plus a few others but I can`t say nothing about the sellers as I don`t know them and they have no iTrader ratings.Sorry I added mine but they fit your install and I am a good seller as you can see in my iTrader.
I could point out a bunch more new ones and ones from other places but again I can`t say nothing about the sellers and it is also a personal preference of what pleases your eye.

Add Polk Audio to that list. Of all the amps listed in the OP, the Polk is probably the one I'd buy.
