Pontiac GTO 2004-2006 - stereo upgrades

what has everyone gone with for their stereo upgrades in the gto? Im just looking to replace front and rear speakers and maybe add a amp to it. i already have a aftermarket deck im going to install. Im not looking for anything extreme and dont even really want a sub at this point because of the added weight. Just want some reasonable but decent speakers.

Eclipse AVN head unit
Alpine DD Linear spilts in the front
Alpine DD linear coaxials in the rear sides
Removed factory subs on rear parcel shelf
2 Eclipse 4 channel amps in the boot
2 Rockford 12" subs in the spare wheel well

I have an alpine deck (came with the car I hate it) I also had two 12 kickers in the trunk but they took up too much room

I just got me an Appradio2 from Pioneer. Will post pics of the install next week
