[QUOTE="rodneypierce, post: 7641397, member: 639381"] Alright guys, I finally got my Eclipse CD7200 HU and got it installed this past weekend. I went to set my gains on the amp and when I did set them to what I had calculated, it was very weak. Both the front and rear channels, and the subwoofer. I have the following: MB Quart PAB5400 Amp. 55w x 4 channels @ 4 ohms (RMS) - front components and rear 6x9's. 300w x 1 channel @ 2 ohms (RMS) - sub Aura 5.25 Components @ 4 ohms - 50 w RMS Aura 6x9 coaxials @ 4 ohms - 60 w RMS MB Quart DWG 254 DVC 10" sub wired @ 2 ohms - 250 w RMS So according to my calculations I should have set them at: Fronts - 14.14 volts AC Rears - 15.49 volts AC Sub - 22.36 volts AC I set them at the above voltage with a 1000hz test tone for the fronts and rears, at about 80% of the HU's volume, and a 50hz test tone for the sub. I had all of the speakers unhooked during the gain settings, and was using a Fluke DMM. With these settings, my gains on my amp were less then half way up (which doesnt make sense considering the amp is rated for pretty much what each speaker is rated for) and the speakers were not loud at all. heck, could hardly tell the sub was even on. I also checked to make sure that all speakers were wired in phase as well. So I went and set each gain at roughly 3/4 of the way up, and its MUCH better, with no audible distortion from any of the speakers. (fronts crossed at 80hz, rears at 63hz and sub at 80hz) Was just curious if I did that right, or what could be the issue?? [/QUOTE]
