ok so got off work early and installed the head unit. very easy, just make sure you get the right harness, I used the Metra 70-1784, swap the red and yellow wires and solder and plug and play. very happy with the head unit. much lighter and sounds great and it has a TON of colors so I was able to get a really good if not perfect match to the dash illumination. I also got the front speakers installed. used JL C2 525x with Jim Clayton rings. I purchased them from JCRTD.com the stock speakers come off easy enough, pry the METAL mesh and then just unscrew. the metal ring is in there pretty good so get a pair of vise grips and rip the metal ring out. so I mulled about how to cut the foam. I didn't want to grind it away because it would make a big mess. Tried a utility knife, hacksaw blade, hot foam cutter, guess what??? I ended up grinding it away. I stuffed a plastic bag under the hole so it would catch some of the debris and used a Dremel to grind away. I tried in the the ring and took a sharpie and traced the inside of it and took away that foam. i assembled the ring speaker and speaker grill completely. then put a bead of RTV silicone in the outer edge of the hole in the dash, then plug the speaker in and then seated the speaker assembly. I didn't need to solder any connectors the OEM Alpine speaker used the same connectors as the JL's I put in. BIG improvement in sound. I haven't tackled the rear speakers yet but it looks like I'll have to drill out the plastic rivets and remove the pod then cut the pod to fit my 6" JL's then put it back in and place new rivets. Also like someone else mentioned probably a good idea to spray paint the grills, at least the silver part as it reflects off the windshield.
