i bought my 240 without a head unit or speakers, although i was told it was pre-wired for a system. i want to remove all the extra wires and cables that are threaded through my car, door panels, carpets, etc. and just put in 4 components… however, i don’t want to tackle this by myself in case i short out my entire car. anyone wanna please walk me through it?? 
pm me if you are still in need of this
hey, thanks for the offer, i actually just wired them yesterday… i cracked two panels, lost three screws, and the panel for the back speakers don’t align properly anymore… but i did it!! thanks again tho.
