2012 HSV GTS Audio Upgrade .
We have just finished Part 1 of the audio upgrade in this new HSV GTS. A pair of ARC Audio Flatline 12" subwoofers in a custom V-Enclosure with a 20mm Plexiglass window. We CNC'ed the logos into the Plexi and then edge lit the panel with multi-colour LED's. The new ARC Audio XDi2000.1 monoblock amp was used to run the subs and an ARC Audio SRI OEM interface was used to pull signal from the factory audio system. We simply could not wipe the smile of our customers face... he was that happy. Oh.... it had awesome tight, deep bass as well!
