Thanks for the help guys !
Sorry for the mess in your thread but if i see someone giving incorrect info ill call them on it.

Thanks for posting up the active sub, confirms that i was correct that its a single sub using a 2 channel amp, unless its been setup to run a channel to each coil then you will only need the 1 sub output from the headunit connected to the white/L channel of the amp. no need for y splitter.

If it has been setup to use a channel each coil then you would need a y splitter but i have never seen this done and it would be illogical of manufactures to run it in stereo when your using a mono/non fader input. Would explain why but i think there has been enough in this thread.

To answer your original questions,
Yes the sub and headunit will be compatible

You will be able to use the stock speakers and power them by the headunits internal amp

Taken from http://www.crutchfield.com/S-AZcrmDN...fo#details-tab
"Steering Wheel Remote Compatibility: The headunit features an OEM steering wheel remote control input on the rear of the unit to allow you to keep your vehicle's radio steering wheel remote controls when used with the optional PAC SWI-PS Steering Wheel Control Interface Adapter (127SWIPS, sold separately); or the optional Metra ASWC Steering Wheel Control Interface Adapter (120ASWC, sold separately)."
Search those model numbers to see if your car is compatable

Havent installed a stereo in an fd2 so i dont know how the aux is set-up so i dont know if you can or cant reuse aux port sorry.

Hope that helps.
