I have an '07 Camry SE V6 and I put a D3 in it... I love it. I didn't bother with the JBL system when I got the car because I knew I would be upgrading the head unit... I am still using the stock (non-JBL) speakers and it sounds decent enough (it's got some good mid-bass but no thump at all). I'll replace the speakers eventually.
btw nice car, watch
