hi guys, i got a problem, my subwoofers are getting this low rumbling sound and when i hit a bump they rumble real bad. occasional when sitting still and i wiggle the head unit the subs pop. is this a bad ground? it is grounded to the bottom screw that holds the trunk latch on w/ 8 gauge wire(same as power) or is the head unit maybe in incorrectly, or maybe a loose remote wire. any ideas? anyone else ever had this problem? thanks for all the help.

 

I am no audio expert but it sounds like a bad ground to me.You might also want to look into mounting the head unit so it does not wiggle.

 

check all of your connections again....

 

9 times out of 10 it's a bad ground
