Altima (4 cylinder) or……. IS F(V8) vs. M3(V8)…….tough decision!

I know right!! Than you have to consider insurance. :tup:

if you dont drive around with your music cranked up loud enough for other passing cars to hear, then Bose will work great and sound pretty darn good.

I happen to like the Bose sound. My wife has a factory Bose system in her Mazda3 and that features one 5" sub under the passenger seat. Overall it sounds really nice so I'm not about to complain about only 2 subs in the 370Z. Of course there are higher end systems out there in both factory and aftermarket forms... so what?

My 2 Cents.... The Bose system does exactly what it's designed for. Fitting a decently massive size of sound while trying to maximize clarity in a tremendously small location (Talking about the "WOOFERS") is a pretty damn good design. But since I couldn't get the clarity that I really wanted I decided to go with this setup all while keeping my subwoofer stock and mounted to the spare tire.

And any standard 4 way AMP split... Half going to the stock bose subwoofer, and half going to the components... All I have to say is man the clarity is NIGHT AND DAY! Kept the stock sub because of minimal trunk space and to make it look "STOCK" but still punch a little bit better with an aftermarket amp. Some people can't afford that though.
