I can touch head units but to be honest, I will leave the amp recommendations up to you guys. I am completely out of the loop when it comes to what is a good brand now a days. I am running Phoenix gold amps, but they are the old technology from before they were bought out (at least I heard that they were, don't know if they actually were or not). I LOVE my PG amps, but I have absolutely NO idea what brand is comparable today. For example, I have never heard of Arc, Audison, or Vibe. I have been doing stereo systems for over 15 years but when it comes to the newer companies, I am in the dark.
