Non Bose MS3 Pre-wired for adding amps?

[RedKatanax9]

I have a 2008.5, non-Bose system. I understand for cars that come with the Bose system, the amp and sub reside under the driver and passenger's seat. So for cars that don't have the Bose system, is the car pre-wired that can be tapped into easily? What I want to probably do is adding a sub/amp 2-in-1 system under either seat, just for that little extra punch. I'm way pass the SPF days. Thanks guys and girls.

You'll need to tap the wires behind the stock HU.

I see, no easy way out then. Thanks!

The stock HU comes out in 5 minutes. Check the "auxiliary input" sticky in this subforum, last page.
