Hi guys, I have the Bose setup in my car, and I was wondering if anyone can send me a link to where I can buy some mouting brackets for the front speakers? I'm gonna be useing Infinity Kappa 6.1 component speakers for the front. I don't have to worry about the rear if i'm gonna be using 6X9 speakers right?

 

There is none that are available to buy... you have to fabricate your own. Which is not hard if you buy some lexan in Home Depot and are handy with a jigsaw.

Apart from the fact that Bose speakers have a non-aftermarket-friendly impedance, no.
Make sure you select speakers with high sensitivity and you should be OK.
