i was told to mail you in this forum about this topic.

i have a JLAudio 6ch amp that i am only using for subs at the moment. i have the amp hooked up and is working fine and great!! (at a stop...) as soon as i start moving the bass stops.. the amp does not go into protect mode or anything. looks fine and appears to be working properly. just bass is gone. as soon as i come to a complete stop again, the bass kicks back in.. why is this. 

thank you for your help in this matter.
