wut up everybody,

i just finished up my first install of a new head unit (sony cdx-mp70) on my 2000 mustang w/mach 460. everything went alright but i soon realized that when i turn the head unit on, there is a single loud "pop" from the speakers and then everything's okay. i am using the existing oem amps (3x with the mach system). does anybody have any ideas of what this could be? if you need more details on the install, let me know. thanks for the help!

The factory amplifier is looking for a 5 volt remote signal from the headunit. Put a 4.7k resistor inline of you remote wire. That should take care of the pops.
