I need your input as I've never upgraded my car's sound system.

I just got a 2013 370Z Base (no BOSE.) The plan is to add a new Navigation head unit and update the sound setting some who.

I am thinking of replacing the 2 pairs of speakers and add maybe some type of rear speakers, subwoofer setup of some sort. My local installation house tried to get me to install a long list of stuff that may be overkill for my needs. I don't need super bass or wake up the neighborhood. Most music I listen to range from POP, ELECTRONICA to Jazz. I would like to achieve crisp, clear sound with decent bass when I am jamming.


My 3 possible options I was thinking are:

(1) Buy a used BOSE sub/amps combo from Ebay and connect to a Navigation equipped HU (Pioneer or Kenwood)? Does it sound any good? I like the fact that it fits within the spare and doesn't take up any more space. Will this make sense or a waste of money?

(2)Anyone tried the slim subwoofer with amplifier combo? How do they sound? (Similar to Pioneer TS-SWX251 or Kenwood Car Under Seat Super Slim Powered Subwoofer) Will it fit in the space behind either seat? Do they sound any good?

(3)Any other suggestion that will not sacrifices the trunk space?


Last question- Will it dramatically improve the sound if I replace the other two pairs of speakers? Any suggestion on what to purchase?

Thank you in advance

Cheers
