Thanks guys for all the support on this thread!
I (with my dads help!) have successfully installed the 2 aura pro's in my couch, and have them wired in series. They run at the same time as my 2 subs which all blend together lovely.
I tried the FMOD .... didn't feel as though I was getting the output from the shakers that I wanted (especially playing battlefied, love the shake caused by my handgun!)... so I currently have two extras they are part # 266-250 at parts express.
I will likely keep one just in case I am watching a movie like saving private ryan. That's probably the best test movie I can find for these shakers considering the first 25 minutes of the movie is like chaos.
I do have one final question ... I did some reading on the tightness of the screws when installing the shakers... apparently if they are too tight it takes away much of the shaking...
should they be "snug", hand tightened, all my strength tightened, or just tightened enough that I cannot move shaker with my hand.
please elaborate on this subject (people with experience..)
