No problem! Here is the link- they did really clean work. They are in San Diego. The location is sketchy, but the dude was super professional. I could do some rummaging around my trunk and see where they pulled the lines from if there is a big desire for that.

I know several of us would appreciate it. I just need to know if/how they tapped the rear speakers and how easy they are to access. I can do my own install as long as I don't have to remove interior panels. Once you start pulling that stuff apart it's difficult to avoid interior plastic rattles. The power and ground hookup is cake since battery is in trunk. If you have to tap the amp itself, then I'll visit a pro shop with some experience.

Seriously. I was sort of planning to tap from the wiring harness going into the amp under the seat.

Also true, plus there's a power plug in the back of the trunk.

if you tap into the rear speakers, you're gonna be limited in the frequency..it wont go low enough for the sub. You need to tap into the Amp under the drivers side. Not hard at all. You can remove the amp and unplug the cable into it, then you can easily tap into the wires. See attached post. If you look towards the end, theres a diagram and it tells you which cables to tap into. I had a couple of pics of the install in there as well.

I just went and rummaged around as much as I could without pulling body panels off- I don't have the expertise or tools to do that, and I couldn't see where the wiring went. I know that it goes on the drivers side, and the amp/sub combo indicates that it is a high frequency input, but that is about as much as I could find out for you. Here are the pictures that I took as well.

Does being under the rear cover seem to muffle the sound from the speaker?

To my (admittedly poor) hearing, it doesn't seem that it is muffled. The door subs provide all of the mid-lows that I could ever ask for, and the trunk sub simply provides the low end grunt that I was looking for. It sounds very crisp to me.
