Please tell us you have your multimeter set on AC voltage, not DC. Reading on DC may or may not give you a reading, and if it did, it'd definitely be wrong. I'm by no means trying to imply you're ignorant or anything (I'm sure you're not), but all of us have a brain fart now and then.

My ex once told me I have a perfect face for radio.

Hahaha I have done that before !!!! But this time I`m positive that its on AC (you planted the seed of doubt in my mind so I tested again...lol)...I managed to get .8 mv with the volume set @ 31 (clipped signal)..and .1mv with the volume on the hu @ 23 (right before clipping)

Dyohn ....are there any tests I can run to see if the h/u is defective?...I was planning on measuring the output of the rear channel. But other than that can you reccomend anything else? I take it you dont think I need the line driver and I felt the same way but the more I try to figure out the problem the more I keep coming up with a line driver being the solution!...Thanks again guys for responding.

I'd take it back and get it tested at an authorized service center. A line driver will only amplify the problem, not solve it, if there is a problem with the HU. A line driver is really only needed when either you have to use long (like 25' or more) RCA cables, or in some competition setups to boost the signal for maximum outputs or to attain maximum S/N.

Just one more quick thing to check. The crossover portion of the unit allows you to attenuate the output by up to 12db for the entire frequency range of any output. You might want check it if you haven't already.
