I'm putting focal componants up front and coaxs in the back. I didn't plan on doing any dynamat but my speakers came with 2 speaker kits(4 10"x10" pieces). I'm wondering where would be the best place for it, it says to use them around the speaker mounting surfaces but I was thinking maybe inside the door or just use all of them in the back for the subs. What would be the first are to dynamat if you were only doing one spot?

Also for the rear fill speakers(2 6.5" coaxs, low power) i was just going to put them in the sails but realized the 2 spots in the back where the factory subs are might be better, whatya think?
