I completed my install today. First I must say I apologize for the lack of pictures. I can't seem to locate my camera. I looked for it for about an hour and finally gave up.
This is probably the easiest car to take apart that I have ever owned. It took me about an hour to replace all 4 door speakers. The only reason it took an hour was that I didn't secure the extra wire to the speakers so the windows would catch the wire on the way down. So basically, I did the job twice.
The factory sub came out easily once I removed all the trim. My car is new so the seat belt T-50's came out easily. I can now confirm that the factory sub in a 2010 Limited is a 1.2 ohm dual voice coil sub. I replaced this with a 2 ohm DVC Dayton NS210-44 8" sub. The new sub mounting flange was slightly larger than the factory sub so I had to widen the mounting hole a tad. I used a dremel and a sanding drum and just wore away some material, test fit and removed more material until the sub was a snug fit. I used speaker gasket foam and placed the sub back in the enclouse. I used the factory screws and they mated perfectly to the factory holes. Once I got the new sub tightened up I sealed the hole in the back on the enclosure that used to have the rear screw that went into the back of the factory sub. I just a small piece of steel and expoxied it to the rear enclosure to assure a perfect seal. I then remounted the factory enclosure and tested it. Right away there was a huge difference.
The bass was much less sloppy and boomy. The output is down just a slight bit but the bass is tighter and much cleaner. The door speakers I used are JL Audio TR570-CXi and they are a vast improvement over the factory "Premiere" speakers that were installed in my Ex. These are a perfect fit and match the 4 Ohm rating of the factory speakers.
All told I spent 159.00 for the 2 sets of main speakers and 99.00 for the Dayton sub and I think I now have a system I can live with. About 2.5 hours of work in total but I have installed many car systems so I would think a novice would get it done in 3-4 hours, tops.
The sub mounting hole is about 7.15" in diameter. The Dayton was 7.35". The depth of the factory enclosure is 4.25" and the Dayton is only 2.5" deep. I used factory wiring adapters for the door speakers and I had to cut the wires at the sub but I was able to get the Dayton connected without adding any additional wire.
In my opinion this mod was well worth the 259.00 and 2.5 hours to install it.
BTW, I now have a brand new JL 8W0 SVC sub that I just purchased for sale. If somone wants it let me know. It is not even open and still in the original shipping box. I'll take 99.00 plus shipping. PM me if you want it. I can take Paypal but if you use a CC I need to pass along the paypal fee which i believe is 2.5%.
