It sounds like you have an open shield ground. To check the shield in your head unit, read through the following page.

I have a California Profile 600 watt amp, I have multimeter and have power all the way to my 10


Power from ignition is setup to turn power On,

Check if +12V is available on "REM" terminal.

Check the speaker wirings , if speaker is connected to the

speaker output of the amp securely.

I have a 1000 w mono california amp is it 1oms safe or 2oms safe


It is always safer to use higher Ohms as it loads the Amplifier less.But you will get the rated power only when you connect the recommended impedance speakers. Eg: If the specs says 1000watts @ 2Ohms on connecting a 4Ohms speaker the Amplifier will only deliver 500watts.But will run cooler and is of course safer.

I have 2 dvc 4 ohm alpine type r 15's and 2 svc american bass


Hi mate very nice amp you got there here is the specs for it



Model: MA Audio HK401SX
Hard Kore Series 1800 Watt 1 Channel High Performance Class X Car Amplifier
1 x 1800W RMS @ 0.5 Ohm Mono
1 x 1200W RMS @ 1 Ohm Mono
1 x 650W RMS @ 2 Ohm Mono
1 x 500W RMS @ 4 Ohm Mono
Fully Unregulated MOSFET Power Supply
2 Ohm Stable @ Mono
1 Ohm Stable @ Mono
0.5 Ohm Stable @ Mono

if you have 2 12s just bridge them and you will have 650wrms at 2ohm running to them or one sub at 4 ohm 500w rms ps they should pump iam running 2 12s with just 360rms at 2ohm and they do the job good luck

How do you get it out of cur mode


Hello whatup_132,

If the M605 fails and displays "CUR", it means that there is excessive current to the amp.

The most common causes for excessive current draw is operating the amp into a lower impedance than it is rated to handle, shorted speaker voice coil(s), and/or shorted or grounded speaker wires.

The amp can operate into a load no lower than 2ohms. First power everything off and disconnect the positive amp power lead temporarily (easist way is to just pull the fuse). At this point you should ONLY have the ground and remote connected. Reconnect positive (insert fuse) and turn on the vehicle ignition and your head unit. If the amp still displays the "CUR" error, the output MOSFET's are probably defective and the amp requires repair or replacement. If it powers up normally, reconnect the speaker wires until you locate the faulty one, and then correct whatever is causing it.

Hope this helps.

California 3600 mosfet discrete 3 ch amplifier 600 watts does not work


It sounds like it's going into protect. To be sure it's not the wiring, disconnect all speaker wires from it. If the light still goes out, check the DC voltage on the B+ and remote terminals. Place the black meter lead on the ground terminal of the amplifier. If the voltage remains above 11 volts as the amp tries to power up, the output transistors are almost certainly shorted causing the amp to go into protect.

Blowing Fuses


If you disconnect the speaker wires from the amp and the fuse blows only after the remote voltage is applied (when the head unit is switched on), the output transistors are likely shorted.
