new speakers in my silverado, suggestions?

[conley916]

I have a 2005 Chevy Silverado ext. cab and right now I have (2) 6 1/2's and tweeter Memphis Audio's and no 5 1/4 in the back so I need to get some speakers for the back too but im going to be running one DC Audio Level 5 18 soon and I want some speakers that can keep up with the sub and scream and won't get distorted. I was looking at some Hertz speakers at the local audio shop but give me some suggestions!
