2 channel amp, different resistance?

I have an Audiobahn A2300HCT amp and well I'm relatively new to a multimeter but not to the concept of it. Observing correct polarity and switching the multimiter to the 20k resistance setting I got a reading of -0.04 and -0.88 out of the other. What does this mean?

Not sure.  What exactly are you reading?Support the12volt.com

I was reading the pos and neg to the subs.

With the speakers connected to the amp or disconnected from the amp?Support the12volt.com

What exactly were you trying to check? If it is a 2 channel bridgeable amplifier, the results you got are normal. I have no idea what checking it that way will tell you. But when you do it, you need to check the left channel with red lead on positive and black lead on negative, notice that reading, then reverse the leads and notice that reading. The meter will react in a different manner for each of the 2 readings. Then move to the right channel and do the same procedure, the meter will behave the same on that channel. It is a bridgeable amplifier, if you use red for positive on both channels, you will get different readings.

If you are measuring the speaker terminals on the amp, then your resistance readings really have no meaning at all.  If you are measuring the wire going to the subwoofers, then you might have shorted voice coils... but negative resistance readings usually mean you are doing something wrong. Support the12volt.com

I was just trying to eliminate possibilites as to why the insulation melted off the wires to on the inside of the sub. From the terminal on the sub to the cone the insulation melted and broke away from the cone at the base. Was I clipping the signal?
