What amps do you have running what? Also how do you have your Becker 780 wired into the amps? Is it possible to switch the amps or at least on the subs to determine what equiptment might be suspect?Does the amp that runs your mids and highs have a feed through that feeds your sub amp? The best thing to do is to start testing the different compenents to see where the problem lies. The other thing to check is how tight the ground is for the sub amp and also how good is the connection at the battery on the power. Both of these things can cause the problem


Let me know what you find! Scott@La Jolla Audio
