alright thanx guys i worked all day and im almost done lol, my new headunit works fine but i still cant get my back seat to lift up , its a 2001 model if anyone knows for sure and one other thing, i soddered the two black wires together for my headunit and harness, but i got one more thats black and has a white strip that says ground amp, since im grounding my amp in the back of the trunk with my subs, what do i do with that wire, sodder it with the other 2 black or just leave it with some electrical tape around it?

 

and also, how do i get to the screws in my trunk to ground my amp, i cant get any of the 4 tricky screws behind my seats to come out, idk there a wierd model and dont just screw out

 

that extra black wire is just another ground you can just tape it or i prefer to cap it off

 

and them screws are probably bolts check the other side to see if there is a nut to turn you can also ground to the seat belt terminals which connects directly to the body, thats what i did just make sure its clean of paint and or rust.

 

all done everyone! subs installed and work! im just gonna keep the volume on them low for a couple of days cause i havent used them in awhile but they were working fine today!
