I recently just added my system. Left the stock head unit and bose speakers and added a diamond audio 12' D6 with a Memphis class D1100 watt amp. Also picked up the newest memphis ported box(thing is huge).Also picked upsirius sat. mounted itinfront of the passanger above the quattro logo, looks pretty clean, ill post a pic if anyone is interested.The subs hit hard and sounds good but that dam trunk and hat rack rattles like a SOB. So yes dynamatt will be beneficial. Im looking into doing it really soon because the rattles off the hat rack will drive you insane.

 

dynamatting the hat rack will not be so noticeable... it's always nice to see pics, and I would like to see a pic or two of your sirus set up... where did you put the antenna?

 

sorry i missunderstood ... one of my favorite things to laugh at are the fools that have thos "NOS" bass bottles in thier trunk HAHAHAH
