Heres how it all started, i was pounding my hifonics bx1605d amp along with my two hifonics atlas square 900 watt rms subs and my cd player started smoking. I installed it myself (I work at a car audio shop as an installer)So i knew it couldnt be any wires touching ground behind the head unit. SO i rip out my cd player and i can see the cd player smoking, (somethething internally burned up in the radio)no wires caught ground. when the radio burned it sent my amp into protect. So i go buy a new clarion755 head unit, hook it up and now everytime i turn my volume halfway up protect comes on. ive tried turning the gain down, and ive tried adjusting the bass. anyone know anything else i could try? i just dont wanna pay shipping to get the new amp if there is nothing wrong with it. o yea, my subs are at 1.5 ohm (parallel)
