ZachG Posted August 15, 2012 Report Share Posted August 15, 2012 Ok so I just put my 2 obsidian 12s in my trunk with my bt-120 & zx1500 wired to 2 ohms, My gain is only half way cause I didnt properly set my gains yet, From outside the car you hear it from 50ft away, at 25ft you hear nothing but rattle from my trunk, wing & rear bumper. I was wondering if I face them towards the front near the opening I have through my rear seats how much quieter this will get and if the rattles will stop being so bad. http://i1244.photobucket.com/albums/gg567/foxzachracing/IMAG1291.jpg http://i1244.photobucket.com/albums/gg567/foxzachracing/IMAG1517.jpg http://i1244.photobucket.com/albums/gg567/foxzachracing/IMAG1516.jpg Quote 1998 Pontiac grand prix gtp supercharged2 12" Obsidain Audio V.1 on a 2011 zx1500.1 at 2 ohms. 20ft of Knuconceptz CCA 0 Guage. 2nd Battery is a Shurken BT-120. Box is 3.5cu tuned at 31.8hz sealed off from the trunk. 14sqft of Dynamat on the Rear deck top & bottom. Soon to be more for doors/roof.

tdsa23 Posted August 15, 2012 Report Share Posted August 15, 2012 even if you flip them around your still going to rattle get some Second skin to help with that and even turning your gains half way can still clip your signal and is that a pre fab box?
