My 99 cobra already had the Mach 460 system, so I left all the stock speakers in place.
I performed the double DIN conversion and changed out the bezels for the radio (obviously), the shifter, and around the gauge cluster since I moved the traction control, fog lamp and rear defrost buttons to the center.
The head unit is a Pioneer Avic-Z120BT. Touchscreen, DVD and navigation. Currently, I'm using a 16GB SD card in there with my favorite MP3s.
There's USB and audio inputs ran into the center console in case I want to hook up an MP3 player or other audio source.
There's two 12" Pioneer 1200w subs in the truck. The amp (2000w Pioneer) is on the reverse side of the box, hidden from view.
The box is a custom made trunk box specifically for the SN95 vert. All the wires are professionally ran and completely hidden.
