"bose pos"? before you talk s*** about the stock bose system on the 3, maybe you should listen to it! In general, I agree that bose is "s***"... many older mazdas (including the miatas) and cars from other companys which have bose systems were all s***... well IMO, that's not true on the 3.... it's pretty damn good for a stock system, covering all the frequency ranges decently... the system is NOT designed for blowning your socks off, but it's designed to be a balanced system
I *have* such a system, so I'm going to defend any bose s*** talking when it comes to the 3... but don't say that I think it's the best ******* system in the world... it's not, there's a lot more to be desired, but it came with the car "without a choice", and I don't regret having it... it's damn good for what it is and the price I got it.... and I'm one of those people who don't give two s**** about car audio, so don't even suggest that I "should've" gotten the car without it and "upgrade"... like I said, I couldn't even get the car without it
as for the MS3, it looks to me it DOES have the bose system... look on the door speaker grille in one of the photos, and you'll see the "bose" emblem
oh wait, I forgot you're in canada... bose is not even an option on the canadian 3s! that's too bad... sucks to the people who want a stock system but don't want to install thief magnets
