[QUOTE="tee, post: 3492821, member: 578367"] Let me get this strait before I mess up something. I have an Alpine MRP-F450 (70x4/200x2 4ohms). I have the Revs (60W) for the first two channel, a sub (150W) for the last two. For the Voltage = SQRT(Power*Resistance), I would use SQRT(60x4) = 15.5V right? For the sub, I would use SQRT(150x4) = 24.5V? Should I use 150, the RMS of the sub, or something a little bit higher, like 170 or something? I would have all of my EQs on when setting the gains right? On the amp, there's this thing called "BASS EQ", should I have it on or off? Would I have to redo my gains if I choose to turn it on or off? The part that I am most confused about is the test tones. I have no clue to which one to use. I listen to hip hop mostly, sometimes rap. Can you tell me which to use to test both the speakers and the sub? I would disconnect both the speakers and the sub when I'm testing it right? Thanks a bunch to whoever answer this. [/QUOTE]
