I have a 2wd DX, thought I would share my setup as it was helpful to read all of yours while I was trying to decide. I went with a high wattage head unit, alpine cda 7892, with component phoenix gold (6 1/2 " and tweeters) in the front and 6 1/2 " coaxils in the back. Sounds extremely good with total cost with installation at a local audio store around 550.00. Later I may add an amp and sub, but this was a great starter set up for now. Thank you all for all the helpul information in these forums.
