Lancer DE 2010 Audio setup
 

Hey guys i just bought a Lancer DE 2010 and i heard from a lot of ppl that the car comes pre wired for everything. I have a subwoofer sitting at home and i saw there is a clip in my trunk which has 4 slots i wanted to know if that is the wire for the subwoofer or not. Does it have the DSP amp which the Lancer SE or Gt comes with? any help?
