[QUOTE="MellowHype, post: 7706213, member: 640052"] Yo im about to set my gains for my Alpine SPR-60c comps on my MRP-f600 amp using a dmm. I have learned most of what i need to do, however theres one thing im not sure of. The speakers take 110wrms at 4ohms, but my amp can only give them 100wrms. To work out what voltage i need, i use Voltage = SQRT(Power*Resistance), but do i use 100w, or 200 watts, as theres 100wrms x2, for the set of comps. Also, I just went and checked my crossovers for the comps, and realised the tweeter level is set at -2 dB, does this make a difference to what tone i use when setting the comps?? Thanks for any replys! [/QUOTE]
