Thank you to Bullet Tooth for answering my last question.

Next one.... after spending the day wiring my fosgate 301s, was presented with the not-so daunting task of hooking up a line converter to my stock stereo.  Through trial and error.... okay... error and error.... I managed to locate the wires that ran to the stock amplifier on the back of the stereo. woo hoo, right?  wrong.  connect converter... stock amp signal go bye-bye.  so I used a few of the few useful morsels I collected at Heald Institute (not a damned word) and ascertained that the connection was already coming in at a line level and connecting the converter was dropping the impedance so low that the amp was reading it as a short. 

question:  Does anybody know whether the other speaker connections on the back of the stock radio are line level or speaker level?  I'd really love to know this before I pull the deck again and strip wires (at least I have the color codes for them.  Thank you 12votl.com).

Any ever used a resistor/cap setup to raise the impedance to get your match on?

Any takers?

Damn, that looks a lot like DYohn's response to the Navigator question yesterday https://www.the12volt.com/installbay/forum_posts.asp?tid=55346&PN=1

Connect the aftermarket LOC to the front left and right OEM speaker wires.  If you have a good LOC which has gain adjustment, it will work without having to "dummy" up the impedance load of the OEM speakers.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

okay.  so I talked to the guy at the local install bay.  Apparently, all of the outputs on the factory unit are pre-amp.  wtf?  so technically, with some solder and wire I could make my own rca females, right?

I would think so.  You certainly couldn't hurt anything by trying it.  Give it a shot and let us know how it turns out.

I for one would love to know if this works!  I did not even think of trying that!

In theory, it should work. I'll try it as soon as I can get a local bay to pop the head unit (since I don't have the ford pull tool). I'll be sure to let you guys know what happens.
