OP, I know what your after. As an audiophile I recommend looking into upgrading your speakers as well as adding an amp. If your running your new speakers off your bose amp that is your first BIG problem. Read over this thread for more information about that.
What to know about Bose
Kicker speakers are not bad but for what your after your going to have to drop a bit more money. Image dynamics Hertz, or focal are a few choices I would look at for higher quality and much louder sound. Even running your kickers off an aftermarket amp would improve sound. It just dependable on your budget. The small speakers your looking for are located behind your seats and I do not recommend using them, just use your front stage for the best sound.
