[QUOTE="cl0udnyn3, post: 8168803, member: 657062"] So basically, if my output is good then my sub is bad? Is it DC volts? Or AC voltage that comes out of the amp? EDIT: Ok so, tested the amp, the woofer has a good 4 ohms resistance. I hooked it up to my amp in the house. Thumps hard. The amp has 14.8 volts when the car is running and is grounded straight to the battery. Re-Checked the RCA cables and they're good. My buddy has an amperage tester and said my alternator was pushing out 150 amps. so i'm good there. When everything is running I have the amp at half of its capable power. I cranked my stereo up loud enough and when I test the output of the Amplifier when there is no bass it drops down to .028 - .050 volts. When the bass kicks in the amp immediately goes into protect mode at exactly .500 volts. When the bass drops back down it powers back on and looks normal. Its not wired bridged either, is that what I'm doing wrong? [/QUOTE]
