I had this problem with my 1320c. Was about to chuck the printer out. The solution I found was: 1. take out PHD unit by undoing 4 twist clips. (read instructions on how to do this without damaging anything) 2. Carefully turn over and tap out all loose toner. (I had large accumulations of yellow toner). 4. Clean up; replace PHD unit and 4. Make sure all 4 toner cartridges are seated snugly in from side door. Good luck
Cables are either shorted, or deck is putting out too much power for input on amp... many new head-units will put out up to 7v on the output jacks (RCA) the amp may only want to see up to 1v will need to consult head-unit manual for adjustment of outputs.
This is normally a grounding problem in the amplifer. If you have a volt meter, check the voltage at the ground of the RCA input on the amplifier. If that voltage is anything more than just a few millivolts then you have a problem in the pre-amp of the amplifier. You should also only connect or disconnect the RCA jacks while the system is off. Otherwise you can get a loud popping noise that can damage the amp or the speakers. Check that voltage on the amplifer RCA jacks with the head unit not connected to the amp with the RCA cables, then if that is OK, check the RCA cables coming from the head unit. You may even have a voltage on those RCA's coming from the head unit, in which case, you have a problem in the head unit. You will be looking for a DC voltage, if you have anything more than just a few millivolts (0.070 +/- DC volts) on either of those then you have found the cause. After that, it will require a technician to be able to troubleshoot the amp or the head unit to determain why you have that DC voltage where it should not be.
probably your power is too short, increase your gauge wire, and your ground wire of the amplifier has to be shortly as possible, and the positive has to be enough to support peak power, you can also put a big capacitor on the positive wire to give some more power while the bass peak.
You have 3 power connection, +12v goes directly to your vechile's battery (make sure this is fused) REM connects to your head unit which tells the amp when to turn on and off (usually very thin wire, comnpared to the gnd and +12) Te gnd you already know where it goes.
Then connect your sub to + and - speaker out put. If you run this bridged it will increase your output, must be 2 channel to bridge to 1 channel or a 4 channel bridged to 2 channels.
Hope this helps.
yes , it is normal for the fan on the amp to turn on when the internal tempature reaches 110 degrees the amplifier is not an intellegent device, all it knows is the temp threshold has been reached and its themostat will close the relay and try to exhaust the heat from the amplifier....I have this same amp, and I live in florida...thank goodness it is a very minimal draw,,,btw if it was a 100 outside it was well above 100 inside your car and even hotter inside the amp ,,the heatsink will conduct heat inside the unit when the unit is off....so the unit is behaving normally...Congratulations for buying a high quality piece of electronics
