I'm trying to intall some db650's in the rear door of my '02 Maxima. The stock speakers are 6.5" but use some mounting bracket. The polks don't fit in the stock location and actually seem too small. It looks like I could fit 6.75" speakers there. Here are my questions...
1) How do I install the new speakers? Do I have to make my own mounting bracket?
2) Why would Nissan use 6.5" speakers in an area that is too big for that size unless you use a giant bracket to mount it? Why not just use a larger size speaker?
