Well they might be wiring somthing incorrectly b/c my friend was an installer for a local memphis dealer and me and him toyed with a quite a few amps and the 1000D sounded just fine to me 1 ohm never got hot or gave us any trobule what so ever. Its a very good quality amp .
If it was my choice over the audiobahn yes , there asre some better brands out the all depends on how much you want to spend and ur electrical system .
