What you need is a Line Output Converter. 20 or 30 bucks depending on where you get it from.

Hello Kelloggrice
This seems just what I have been looking for.
I wish to add a sub or subs to a system that uses a passive preamp into a Charlize T-amp.
Am I to assume that this schematic will allow me to take off a line output from my loudspeaker terminals without affecting the speaker's performance?
TIA

That schematic should not be used. Many speaker negatives will have DC voltage on them. Still others will have signal. Many amplifiers will have problems accepting either. Depending on the amp and the signal source, this could cause severe (expensive) damage to the signal source.
As Perry said the circuit should not be used for car head units. As a bodge a third resistor can be added to avoid/minimise the damage to the head unit and not inject so much garbage into the amp ground, but a transformer is the only real way to do it. But a good transformer that performs in the bass is not cheap nor small.
