If there is no protection light on, be sure the input is on. Some head units need to be turned on manually (factory set to OFF).
Verify the subwoofers are wired properly.
A list of your components would help to solve your problem.
If it is new, it should still be under warranty - worst case scenario output transistor(s) blown, or power supply bad.

Hello roets81,

Check the voltage at the amp. It's possible that the voltage is either too high (above 16V) or too low (below 8.5V). Also make sure that the amp case is not grounded. If these check out OK, the most likely cause is that the amp itself is defective and requires service.

Hope this helps.

SOURCE: my ma audio hk 898 will power on but will not push

Hello 76firebirdfo,

If there's no sound at all from the subs and you know they are good, there's probably no output from the amp. It's either wired incorrectly or it is defective.

If there's some sound but just not loud enough, then either the amp is not getting enough of an input signal from your head unit, or the amp settings are not adjusted properly. Adjust the crossover and gains for the best output to subs. LP filter on, crossover frequency at about 80-100Hz, and gain to maximum without distortion when head unit volume is at about 3/4 maximum.

Hope this helps.

Fs is a thiele-small parameter, meaning resonance. You can use these parameters to simulate the woofer's bass response in different boxes etc.

This is an indication of an internal problem. Typically this is shorted output transistors. Expect a parts cost in the $25-$40 range for this repair.

Why Harman Kardo HK 3490 goes into DSP voltage protect mode


This amplifier can go into protection if one of the low ohm resistors on the power module that is soldered to the transformer is defect. Check out R951 and R952, they are both 0R47 (0,47ohm). They are often broken and measure some kilo ohms.

I have a ma audio hk-602sx and my protect light wont go off and somthing is clicking inside and as it clicks the protect light blinks.


Disconnect the speakers and then try it again...there may be a shorted speaker or wire if the amp comes out of protect after you disconnect the wires...if the amp stays in protect after you disconnect the wires then there is a problem inside the amp with the circuitry and it will need to get serviced by an electronic tech

Reciver goes into protect mode as soon as I turn it on.


Remove speaker wires and try again. If it still goes into protect mode, the problem is internal...shorted power transistors or some other fault. Check fuses also.

yes it can, it sounds like its over heating, make sure that your product is able to get fresh circulated / cooler air
if it already is, then it probably is a faulty product.

Amp comes on and goes right into protection mode


Turn the reciever on for a second or two and then off before the protect mode shows up on the monitor. Repeat this step about five times and check to see if the reciever does not go into protect mode. If it does go into protect mode try it again. Dont know if this is the proper way to fix the reciever but it worked for me. Good Luck

Amp heats up and goes into protect mode


Hi Saint108. You're describing it well, and i know what the problem is already. The MA audio amp, can't hold with a 2 ohm load. It's too low for that amp, that's for sure. Those are budget amps and they are not well built enough to handle low ohm setups like that. It's overheating and there's no ways around it.. Other than wiring your subs differently ! Just wire your sub directly (not in parallel) in a 4 ohm load, you will notice it will stop overheating that much. Do it quick, you'll most likely fry your amp giving it such hard work !! The HUM you're hearing could be related to it also. Try that, and keep me posted on the status. Thanks ! Cheebster.
