If you want to upgrade your sound set up in the ST or The RS this set up is compete and plug and play. This set up was custom built by a professional audio shop for a 17 RS
will come with pics of which wires to splice in for an easy plug and play.
This has a Built In Base level control knob built in to the lower portion of the steering column plastic so you can turn up the base or turn it down. The sound was great.
This particular set up if you install the base plate that holds the modules requires you to eliminate the foam pieces in the trunk lowering the whole thing down few inches giving you more space in the trunk. The Cloth trunk piece is set on wood pieces which are Welcrowed to the body of the car. No vibration/rattling noises.
