Nice job Viper
I'm considering going the same route and have a question.
First off I already replaced the center speaker and the lower front door speakers as well as repacking the sub with Poly-fil. The system sounds way better but I'm still looking for more punch overall.
Rather than more Boom Boom Boom , I want that more powerful mid hit you get from snare drums, congo drums etc. (Ratta tat tat rather than Boom Boom Boom) The Sony system I have is still too muddy for my taste.
My wife has a Bang & Olufson system in her Audi and to me it sounds incredible, so that's kind of my goal .
Could you explain the difference you got with the Amp/AR module change
Thanks
Tom
