You will need to recode your OEM HU to HiFi outputs for this to be effective, if not then you
could need to add a Cleansweep:

A Cleansweep will blow your budget and still you will need to get the OEM tweeter pods and a Stereo harness.
You could streamline this setup by just getting one set of DLS, the SWS-8 a XD400/4 and a Cleansweep instead. The rear speakers will be driven by the OEM HU. That should keep your budget barely under $1000 with all audio equipment needed -no labor, amp power cable kit or RCA included.
