hey guys,

i just recently got a 2011 5.0 with the shaker 500. I want to install a set of component speakers in the front door. my question is do I need a new h/u as well? I don't really want to replace the h/u as I'll have to repalce the whole front dash.
Also what components would you reccommend? i have a JL 300/4 amp and budget for the speakers would be up to $800.. music is mostly rock/metal

Thanks!
