[QUOTE="Steven, post: 91226, member: 544311"] It doesn't measure impedance. I used an L-Pad to ensure that the device, when installed, won't effect the load on the amplifier. If you use 4-ohm speakers the load on the amp is normally 4-ohms. Without an L-pad my board once attached would radically change this load, thus change the performance of the stereo. With my current set-up (4-ohm subs), I built an L-pad onto my board to maintain the 4-ohm impedance. As the subwoofers impedance changes the L-pads Impedance changes (because they are being driven evenly) so that the Amp always sees the Impedance of the Sub [/QUOTE]
