My bad didn't mean to sound pissed off or anything but I posted this so people could look at it and refer to it so they can search the forums. Both your questions have been covered in other threads. Its not a problem that you asked here...its just you could have easily found the answer. Now to answer your questions...I got my spacers from "jtsherri" (post #9). You can get them from him or make your own. You can also use dynamat and some have used some kind of weather strip thing...not sure on that one.

The impedance of the factory underseat subs in the Logic 7 system are 4ohms. Therefore, if you are only upgrading the subs than 4ohm SWS-8's will be required. If you want to power the SWS-8's in parallel with an added amp that can handle a 2ohm load, you need the 4ohm versions. The ideal way to run the SWS-8's would be in 2ohms on a 2-channel amp (in stereo).
