First start by accessing the factory amp. Pull it out, there are 5 wires you need to splice into.
You will need to buy a hi-low level adapter, its a device that converts regular speaker wire to RCA cables.
1. Cut blue/grey wire, that should be the negative(-) speaker input on the high-low level then re-attach it to the factory harness.(right side)
2.Do the same for the blue/violet that is the positive input (+) for the right side
3. Do the same for the Yellow/grey, that is the left side's negative (-).
4. Do the same for the Yellow/blue, that is for the left side's Positive (+).
5. After getting all these wires hooked up to your high low level adapter on the other side there is an output for rca's...hook these RCA's up to your amp.(red and white)
6. There is a solid white wire, this is your remote turn on, splice a wire from this also. This will go to your REM (remote turn on) input on the AMP.
7. Run an 8 guage wire from the battery (life up the rear seat run a wire from the battery to above the arm rest, there is a hold right in the back of the seat over there somewhere) Make sure you have an inline fuse within 18 inches of the battery with a 30 amp fuse in it.
8. Remove the back panel which is behind the seat(in the trunk) this is attached by plastic screws, take those out and the whole panel will come out. that wire to the positive (+) on the amp.
10. Ground the amp with an 8 guage wire to the chassis.
11. Hook up standard speaker wire from the amp to the subs.
12. Turn your stereo on and enjoy!

BTW: Do not hook up the fuse from your battery until everything is hooked up, putting the fuse in is the last thing that should be done!
