be aware when you are using a multimeter set to its lowest resistance scale - to measure the resistance of the bass panel:

* the leads themselves have a certain resistance so, say, if the actual bass panel resistance is 4 ohms ... the meter might read 4.7 ohms. You measure the resistance of the leads by connecting the 2 leads together and seeing what the meter reads - then you subtract this number off all future readings.

* your typical multimeter is not very accurate at low resistances. You really need to get hold of an auxiliary device which is used in conjunction with a digital multimeter, to get it to give accurate measurements of low resistances.

I bought the following kit (here in Australia):
