So with this, there is a ground to the back seat mount, a wire to the battery and a wire to the fuse panel.( I'm sure this is a sin in the audio world.) The last truck he did this to was his '03, mine is an '04. If there's one thing I've learned so far, it's that this '04 is differnt from his '03 in more than one way.
So on to the problem....power from some where is draining the battery. Had the battery checked and the alternator, both I was told were fine. Wires and connections are good. Nothing exposed. Disconected the the sub from the battery, so there shouldn't be power source there. Could it be pulling power from the radio? Which is ultimately conected to the battery. I'm guessing it needs to be wired different. At any rate, I've had to jump it every morning for the last 3 days, which is when this problem started.

Wouldn't that in theory work? That's all that was sent through there anyway, so without an amp it would just have the output equal to a speaker. Could that work? Get the harness that was for the OEM amp, and connect it to the speakers?

The model # for the radio is: 8L3T-18c815-KC
And it came out of a Standard cab 2008 F150. So right there I know that it didnt have a sub. There are 3 plugs on the back of the unit + antenna. My truck only used the big plug as it was a standard AM/FM/CD player. Knowing this, what can you tell me?

Anyone have one?

I am also planning on adding a sub/amp. Should I just say forget the whole thing and buy a new aftermarket headunit? By the time I get a line level input I'll have put over $100 in it andI can get a Pioneer double din headunit for like $400.

I have a 2006 Screw that I replaced the stereo with a OEM Audiophile system, and I purchased a OEM Sub on Ebay. I have the connector at the rear seat, but I cannot located the one in the dash. I ahve just about taking the complete dash apart looking for it. I have even opened the bundle in the lower radio cavity and can not find the connector. I have ran my hand up and down every single metal bracket under the dash to see if I could find it tape somewhere to include behind the glove box. My question is where is the wire, if it is in the rear it shoudl be somewhere in truck. Do they just dead head this if the truck does not come with the Audiophile system. If so can I build one and get this to work. I would can it all and go after market but I like the steering wheel controls that the OEM system has.
