[QUOTE="DRBOOM, post: 8672431, member: 676005"] Few issues come to mind, but could be [LIST][*]RCA setting set to speakers (does the head unit opt you to chose either speakers / subwoofer??? [*]If it does not give you the option, chances are, you are running them as speaker and it only jumps when there is bass thump [*]Low voltage from head unit - Those and most head units these days don't have a high voltage output hence your only hear something when you turn it up 3/4 volume and your amp gains set high [*]Again, agree with my man, Jeffdachef to try another head unit to see if the problem persists, If you can borrow from a mate and run one, then that can be confirmed as well [*]The head unit could be faulty too, so get a replacement and / or upgrade to a higher spec unit with more RCA's as the one you have is only entry level one and does not offer other features such as subwoofer volume / subwoofer frequency choice,/ subwoofer volume/ phase option. Also get a unit with built in high pass filter so you can run your front and rear speakers on high pass. [/LIST] [ATTACH]4913._xfImport[/ATTACH] [/QUOTE]
