[QUOTE="FML, post: 8372603, member: 630747"] There's an answer to all this. What impedance are your woofers? If 2 ohm, then you're fine. Even if you Have a top notch meter, a little variance is to be expected. Im at 1 ohm, and i have a bery high quality meter and i normally read between .9 and 1.1. Secondly to test RCA's, set your meter to voltage. One lead goes on the center pin, the other on the shield (circle part) . Depends on your HU and what settings you have, but generally should be between 2 and 4 volts. And unless you are super concerned about dialing in gain or getting a clamp test, testing the amps output terminals wont do much for you. If everything is working, its safe to say its fine. The fact that you think you get different volume at different times can mean a number of other things. A bit more info on your setup? Including vehicle [/QUOTE]
