So I'm just about to take delivery on my g35xs in a few days. I haven't even gotten it yet and I'm looking to do some upgrades/modifications to the car.

I'm just wondering though how is the bass in this sound system? ('08 prem).

Also, if I decide to install my own subs - my friend is willing to sell me 2 of his 12" audiobahn DUB200's enclosed with an audiobahn 1200watt amp all for $75. Now these subs are cheap I understand that but I'm only looking for a little bit extra bump in the sound system - not setting off car alarms as I drive by. Would these subs be OK or are they real POS's?

Thanks.
