First of all, Clean job on your deadening and is there such a thing as overkill! LOL Coverage is the key and i too only want to do things once if possible so OCD is ok with me. I have two set of T265 in my 03 Lancer, font & rear doors active off a DEH80-PRS and they rock. I spent about 60+ hrs sealing my doors to about 98% and deadening w/ Coolmat and Dynomat acoustic foam to about 85% coverage. The doors are solid as hell which make those T2 scream with clearity being pushed by 2 RF T400-4s. The whole system is tuned w/ my DD-1 even though i still have some sytem tweeking to do it sounds good and made a distance sound test vid that show the car and what sound deadening and RF power products can do. But as always theres still more to do, I just got my sound deadener for my trunk, I ended up going w/ Road kill extreme and 1/2" dynomat acoustic foam, plus want to use expanding foam in cross members to strengthen the trunk lid. This was a great thread with lots of good pics and ideas for sound deadening. Thanks guys and anyone wondering how the T2s sound check out my vid for Youtube!
