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.

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.

Can i turn up the amp manuelly in the audi A8


Yes. Find the gain control knob on the amp and turn it up to increase the volume. Be careful though, as turning this too high can cause clipping and distortion, which can damage speakers.

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

Need to pick perfect amp


I suggest to use separate amps to your sub, get a 2 channel amp for your sub and 4 channel amps for your speakers.

Here are my Top 5

  • Lanzar -OPTI4000D
  • MA Audio- HK-4000D
  • JL Audio 1000/1V2
  • OPti 22.2 Power Amp
  • AudioBahn-A5100T

My ma audio hk 4000 amp is powered on no sound coming thru subs amps brand new


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.

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.

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.

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.
