[QUOTE="FoxClubNiner, post: 8506582, member: 670077"] Thanks for the help ya'll. I finally got a chance to look more into it. I set my settings to what you said and it didn't change anything. Then the sub made a loud pop. So I turned it off. I checked the resistance of the subwoofer. It has 1.9 ohms. I think this might be normal according to this spec page: [URL="http://www.polkaudio.com/db1212/d/1086"]db1212 - Polk Audio[/URL] The resistance of the RCA cable from the head unit to the amp is .4 ohms on the left channel and .4 ohms on the right channel. I had to use 10 foot leads so I think that's why they weren't .2 ohms. Seems normal. I checked for problems with wires grounding to each other. They are OK. The available voltage on the left and right channel is .039V when measured going into the amp. The amp power wire has battery voltage. And the ground for the amp is good. All fuses good.
