i just put my new system in the other day and im having this problem with it where my subs a reacting when they are not suposed to. iv had many systems before and this has never happened. for some reason my subs will go off when i hit my breaks or when i turn on my signal lights and even if i tap my dash the subs will be set off. i thought it might be my rca's picking up a signal somehow when i hit my dash and sending it to my subs but i put differant ones in and the same thing happened. anyone have any advice. please post back.
