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.

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.

SOURCE: how do i drop it down to 0.5 ohm

there are no settings on the amp, if it is made to be stable at .5 ohm you will need 8 voice coils to make .5 ohm, if your subs ar 2 ohm, you will need 4 coils to make .5 ohm when hooked in parallel

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

I have 2 MA Audio HK 15 X 2 subs and voice coils are blown. How do I fix them


There is little chance that you can do anything about it. The exact voice coil would have to be identified, the old ones taken out, and replacing them is technically difficult/impossible without the proper tools and experience.

Open the unit and inspect for a bad or cold solder connection on the side in question. You can compare the circuit trace with the other that is working to verify the connections.

MA audio HK 12 competetion subwoofer, the 1500 rms one, what is the ''Fs'' on that thing? There website doesn't tell me. Any guesses if you can't find the answer?


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

MA Audio EHO152's


My honest opinion is that MA Audio is not in the same category as the other subs you mentioned. I buy a lot of electronics on ebay to avoid the giant mark up from stores. I found some MA's and got them for $.01 because no one wants them. However - any sub can preform well if you put the in the right box. I am a technician, not a salesman so you just heard my opinion for an experience standpoint.
