@trumpet; i intend to have the work for the speakers done by a shop. Ill have my amp and stuff already installed. They will just need to wire it up. Id like to either pre-purchase the parts needed myself, or know what they need to do so they dont blow smoke up my a$$ and i end up with like $1k in bills from it on stuff i didnt need.
