Speaker Sizes, Harnesses and Kits for the Mazda3

haha, well, i went ahead and used this diagram.. All the wires were there, altho some were the same. Like I had two White with Red stripe on the harness, but the + and - for front and back are located seperately in their own group of 4's. I'll finish the install tomorrow and see how it goes...

Hey Im new to forums,
Where can I find the 2009 BOSE speakers, wiring harness for stock head unit?
The guy I bought my car from put in a kenwood that sucks, and I want the stock back in

Thanks!

What's the wiring like on gen 2's? Mine's a 2012. I upgraded the speakers and since I did it myself I got to realize that when speakers are wired incorrectly (mixing up positive and negative terminals) they sound like crap. I'm pretty sure at least 2 of them are wired incorrectly, causing them to "phase" and cancel each other out. Since this phasing effect is most prone on low frequencies, I have almost no bass. Anyone know the wiring diagram for gen2's? I know I did it wrong because if I set the fade and balance to play only on a single speaker, I get more bass than with all speakers together!
