[QUOTE="Incognegro, post: 1172757, member: 562855"] Ok need some help here’s the scenario: System: Pioneer 7500 HU 4 gauge all around Diamond Audio CM12D4 subs (4 ohm dual vc, 500w rms.) MA Audio HK1998 In 95 ford exploder First off to preface the problem, the headunit is wired correctly, there are no blown fuses anywhere in the system(power, amp, etc.) all the connections are good, and all the wiring going TO the amp is correct(power, ground, remote turn on. Problems: The amp receives power(blue light is on) but also the blue protect light comes on too, and we have no audio. The subs are dvc 4 ohm, but are wired in 1 ohm parrell as given by the manual on the diamond site. The subs are wired correctly for this, and are connected to the amp properly. The rcas are plugged into the right channels as well. The amp will turn off if I unplug the rcas, turn the head unit off or shut the truck off. I cannot control the amp on/off through the headunit like I should. I have the filter set to low pass not full. My thoughts/questions: In the amp manual where it shows how to wire the different loads for the different model amps that it covers, for my amp in mono mode it says 2 ohm minimum load, however I have been told that this amp is 1 ohm stable and can operate at that? Do I have the wrong amp? Why can I not seem to flip the amp on/off from the headunit- the blue/white output on the back of the headunit is connected to the remote wire correctly and is hence connected to the amp. I think that the amp (protect) is on because maybe there is a “short” in the system. Meaning that it understands the incoming power(its on isn’t it? Lol)but it doesn’t know how to put it out to the subs (hence the protect light?) and “protects” the subs Im assuming? Or the real question is did I fry them some how? But even if the wiring on the subs was wrong, wouldn’t the amp take the hit first and not pass it on? (meaning blow the fuses on the amp right?) Before I wired it using the diagram in the diamond manual, I used the rf site and it came out different, and the subs didn’t work with that one either (2 subs, dvc, 4 ohms) I used the one ohm option I think on the rf site. 2 DVC subs at 4 ohms into 1 ohm load. Like I said this one didn’t work. Really need help, been 3 whole days at this and still doesn’t work…ahhh TIA J [/QUOTE]
