This may be a stupid question but, where is the placement of the nine speakers for the Bose system? Door and tweeter x2, center channel, and two speakers behind the rear seats make 7. The Bose system DOES have 9 speakers, as it says on the website? Or am I blind and missed it

 

Here is the speaker location on the 2004 RX-8 with bose system:

1 — 3-inch neodymium centerfill speaker in the center of the instrument panel
2 — 2-inch neodymium mid/high-range speakers in each front door
2 — 9-inch neodymium woofer with two state modulation amplifiers in each front door
4 — 2 2-inch mid/high-range speakers mounted with 2 6x9-inch woofers on the rear deck

I am looking to replace the stock speakers (Bose) with some Alpines but after reading about the setup form Bose and the difficulty finding something easy to replace on crutchfiled I may not so sure.

Good Luck
