Thank for posting that link! Yeah, I'm only at the first stage right now...all the product is sitting in the closet just waiting for the better weather. up to this point....the radio was changed to a Pioneer z110bt, and the dash kit was painted gloss black and sanded numerous times. The damping is 3 layers...first layer is dynomat exteme...i went over board with it...you only really need to cover 25% with this stuff...second layer is CCF, and the 3rd layer is MLV (mass loaded vinyl)
The system will consist of
Front Stage- 1 inch Hybrid Audio tweets, and Hybrid Audio 3 inch mids in the a pillars ran off a JL slash 300/4, thenn in the doors are Hybrid Audios 6 inch woofer running off a JL slash 300/2 and for subs two Stereo Integrity BM's ran off a Slash 1000/1 oh, and a Bitone.1 is the brains to the whole thing
oh yeah...been doing this way too long too!! started back in the late 80's before i even had a license ( neighbor owned an audio shop) Then I read as much as i could about it, and designed 100's of systems, worked in a few shops during college, competed on the Iasca circut, and made it to the world finals in '99. Now i jsut do it for fun and a stress relief ...hahahah
