Posted March 7, 200817 yr hey guys i have 2 12 L7's being powered by a Eclispe DA7232. All was fine up until a few weeks ago when i noticed that the amp occasionaly shuts off after a few mins of play. all the wires are fine and the other amp works fine.... i was thinking maybe it might be seeing low ohms but the amp is not even warm...any ideas?....thanks guys
March 7, 200817 yr not familiar with that amp but does it go in to protect? does it just turn off for a second or shut off completely?
March 7, 200817 yr Can you check the ohm load that the amp is seeing with a DMM? Just because the amp isn't getting warm, doesn't mean that the load is optimal.
March 8, 200817 yr Can also try playing it at lower volume it stays on at, and see if it gets hot after 20-30min (too much current).....or does it do it at any volume? They can shut down before they get the sink warm if the protection circuit senses voltage out of range, it takes a little bit of time to warm the sink and with a short/etc it can cook the chips before the sink gets hot. There are other things that can happen that might not heat it up anyway.
