[QUOTE="keep_hope_alive, post: 8660650, member: 576029"] There are several items to check. #1 - check you don't have the coils wired out of phase - the sub wouldn't move if that was the case but you'd still meter 4 ohms. You can verify with a DMM and measure VAC output. #2 - make sure the head unit outputs are properly configured. The menu on the HU let's you assign the rear/sub outputs. I assume you have the outputs set to rear so the front and rear speakers work. #3 - the amp inputs are configurable so the sub channel can get the signal from the other 4 inputs (which it seems you need) so set it at 4ch.
