Sorry, I did not know where to post this since in the Audio forum I need to chose a car. I do not have an TL anymore. I got a 2003 Mazda Protege 5.

I am looking to purchase a 5 channel amp. I want to run a single amp for highs and a single sub.
Any recommendations? Opinions?
I was looking into the new Alpine PDX-V9, but I also see other Alpine amps. I use to have always have Alpines and had good experience with them. Your input is greatly appreciated.
