components suggestions

I'm going to upgrade my 6.5 components and was looking for some suggestions. I would like to stay in the $500 dollar area. I am currently using a Precision Power Black Ice 1000.4 to power what I currently have running off of a Alpine 164bt HU. Looking for good full and clean sound.

I didn't find the right solution from the internet.
