    Subs aren't hitting PLEASE HELP!!!

    So here is a little background. I have had 2 alpine type r 12's hooked up to an mtx thunder 81000 amp and my door speakers were running off the head unit. My subs would bband hard and I loved them but today I decided to hook up an amp for my door speakers and I got it all done and the door speakers sound amazing but for some reason my subs just don't hit like they used to at all I have no idea what happened, they are on and working but just don't hit at all. If anybody can help me I would really appreciate it thanks guys!

    That sounds correct. Make sure your sub is crossed over at around 80hz and none of the deck settings have changed

    Really on only 1300 rms? I figured it would be fine but I'm not sure. Could it be that I didn't use a distribution block for my power wire or something like that since I used 2 power cables instead of a distro block.
