if you want to be heard, go with a vented/ported box. They're designed for SPL, not sql. Sealed boxes are for SQL but have a flat response. Also the box has to be tuned for your sub which is why it's always good to have a box custom designed for your sub instead of going with prefab boxes.
If you don't go with a mono amp and sub, the rear deck 6x9's are good enough, but they'll sound much better with aftermarket speakers and an aftermarket head unit. To me, the 6x9's are mid bass...not designed for producing real lows.
I just got my 09 altima and can't really stand the factory speakers. Hoping to use my tax refund on a much better system as I was able to retrieve my Audiopipe 1500D mono amp after my other car was totaled. This time around I'm planning on going with a smaller 2.0 cu. ft box instead of a 3 cu. ft box. I'm basically a bass head enjoying TONS of bass!! I had a 12" Hifonics Olympus 1600 rms dual 2ohm sub that I used to blast on the freeway!
