[QUOTE="eskimochaos, post: 4590993, member: 592287"] Ok, yesterday I spent the entire day at work (had nothing to do) learning how to set the gain. Went to radioshack got a multimeter and went to it. Using the calculation, the measured voltage on a 0db 35htz test tone should be 40. because sqrt(800x2) = 40. So I adjusted the gain accordingly until 40V was hit with 3/4 volume on HU. Does that mean that the subs were getting 400 each? IDK but I think that the Alpine m850 is rated @ 14.4v but I was getting this voltage idle so that means its performing efficiently @ rated RMS w/o clipping the signal? Now Im soon to be the proud owner of a AQ2200D. I know this pulls more power especially since I have stock electrical. (130 amp alt) will this increase in power prevent me from getting sqrt(1300x2) 51V if the amp is rated @ 14.4V but Im not getting that @ idle? Basically, if the AQ2200D is rated @ 1300rms @ 2ohm @ 14.4V will I ever be able to achieve 51V on the multimeter at idle in the car. How can I measure voltage @ idle...been using my 9500i but that is only plugged into a 12v source so I guess its limited? IDK how to word that but I tried. Thanks in advance? [/QUOTE]
