I listen to contemporary Jazz and hit the classic rock from time to time.
Either thru CD or Sirius.
I'm not looking to change the head unit, but what would you guys suggest to bring out some decent highs and lows, without a radical install?
I'm really trying to bring quality to the Jazz.

I'm all ears...

 

DLS UP6 with either JL "slash" series amp or DLS amps. I love mine.

 

Do you have the Bose system? If not, I would make a slightly different suggestion.

I would suggest the 4080 premade box with a DLS MW110 sub for the sound you refer to - tight, acoustic, no thumpiness . If you don't want to go that route, I'd upgrade the 6x9 woofers with MBQuart 6x9 woofers (best by-nine woofers I've heard).

DLS UP6 components are the stuff for the front...

 

Change out the speakers to Infinity Kappas if you have the stock bose system. You will def. be able to tell a difference.

 

Yes, it's the Bose system.
Would speakers alone make the difference I'm looking for, or do I need the change the amp?

 

That's a good question.

It's hard to tell, based on what you are looking for.

I have some OEM-amp-powered speaker upgrade kits for Acuras and Audis. If you want to try one, reply to my PM.

 

Hey Ken, I might be interested in a few of those kits.

Shoot me a PM when a good time to call would be.

Sorry to hijack your thread gbest, Lots of good ideas above, not much more that I would have suggested.
