I am new to the forum and need some help. I have been researching this site and several others. I have a 2007 f150 xlt 4x4 super cab. It has the premium radio option. I want to add the oem sub box. I found the oem connector under the carpet and bought a used box from ebay. I plugged it in and no sound. The radio part number is 7l3t-18c815-ma and has two plugs on the back. It has sirius radio and the aux connection. I can add photo if needed. Research says i need 3 plugs on the back but most posts seemed to refer to 04-06 radios. I looked all over behind the radio and under the dash and cant find a unused plug. I found what i think are sub wire in the connector behind the d/s kick panel. There is also a fuse in the #38 spot. So, is it possible to have the sub box plug but it not be connected to the radio? Do i need a different radio and/or a extra wire harness? Any help would be greatly appreciated.

first I would say you need an Autophile head unit.. Autophile was the system upgrade with the sub option.. not sure there is a separate plug for the subs.. it may be in the main plug itself.

I believe the correct HU will have 3 plugs on back, there is a thread that goes over this subject.
