Pre purchased 3/4 of this just waiting for the rest to arrive then get into installing it all..

Pioneer competition 6v 4rca headunit - can't remember the name exactly

Front- 6.5" Alpine Type S 80rms 2way splits -are being run off a option audio 4x 75rms amp to do front and rear

Parcel Shelf- Kicker CS693 150rms each 6x9s - Dynamat on the top and underneath the parcel shelf, also filled the factory sub hole with some mdf.

Sub- Pioneer championship pro 3500w (1000rms), or Dual Rockford Fosgate p3 600rms (Unsure as to which one- a wait on both models)
Option audio amp to run the subs is the 4000w 2000rms @1 ohm, 1500rms @2ohm and 900rms @ 4ohm.

Using Stringer wiring kit, and using Focal speaker wires

Forget the 6x9's and use the extra $$ towards the front stage.

Which ever sub you get, get a box designed specifically for it.

Never used OA amps, so no idea what they're like.
