Ok all, need some help!!! Did the 4/6 drop on my CCSB, and have had a crazy vibration since at highway speeds, 68-78 ish MPH. About to just lift it back up until it is gone! Had the shop put in 2.5 degree shims before the last road trip, and not a bit better. HELP!!
Used the McGaughy's 34170 adjustable kit, and used the 4/6 option. It comes with struts and rear shocks. The rear bump stops were a pain. I have 24" Versante 228s in chrome. We originally ordered 295/35-24 Nexen tires, but they were way to big. Putting 275/30-24s on them. Will put updated pics once they are mounted this weekend.
I have about $750 in the system, not counting the amps. I already had the two Fosgate amps. You could use a couple RF Prime amps and be out for about $1000 total. If you went with the same amps about $1,500.
I decided after a week of having the Crew that the factory non-Bose system really sucks. I will be installing an Audio Control LC6i to convert the factory signals over to RCA. I am running 2 Rockford amps, a Power T400-4 for the doors, and a Power T400-2 for the sub. The door speakers are Rockford P1675 3-ways in the front doors, and P165 2-ways in the rear doors. I am using a single 12" Rockford P3SD4 under the driver's side rear seat in a Subthump box. (http://subthump.com/product_info.php?cPath=1_72&products_id=457) The power and ground will be Lightning Audio 1/0 gauge to the back, and then 4 gauge to the amps. Running 14 gauge speaker wire to the doors, and 12 for the sub. I'm going to try leaving the dash speakers hooked up to the factory outputs, just to have some fill in up front. Lots of install pics to come.
I did a custom 3" single exit, and used a Magna Flow muffler. We dumped it just over the axle. It sounds great in my opinion, and is not loud. Here is a video of it while driving:
