I'm having trouble picking a new amp, not sure wether I should go for a Rockford Punch 450.4 or Orion 8004. I just saw Orion yesterday, and yeah, its super big. I dont know about the quality though, and if its durable. What do you guys think???//content.invisioncic.com/y282845/emoticons/uhoh.gif.c07307dd22ee7e63e22fc8e9c614d1fd.gif
