Stereo upgrade suggestions?

Thinking of getting a new stereo- I've got a blown speaker in the passenger door of my ‘05 DC; it has the JBL 6 cd/cassette head unit, which I’d like to upgrade to something with Bluetooth or usb connectivity. Don’t necessarily want to replace the amp or the speakers that still work, but figure a new receiver and a pair of front speakers would be a reasonable upgrade. Anyone got any suggestions? Crutchfield? Local shop? Any info would be appreciated!

 

Hard to beat Crutchfield if you're doing the work yourself. If you don't care about having a CD player you can get a pretty decent radio for under $100. JVC is running a sale where if you buy a head unit you can get 2 pairs of speakers for half off.

 

People still using CD's? It's ok, I have car that still has a tape player.
