Low independence light comes on and a humming sound what is causing this?


Humming from subs? If from inside amp, your experiencing a problem with a driver board. It makes transistors latch on and loads down the transformer, causing light to come on. And vibrations "hum" from transformer.

I looked up the correct way to wire my JL 13.5W7 1.5. Therefore it said to wire it in parrallel. I understand this will put it at .75 ohm. As I start to turn it up it sounds great, very loud but once the...


1000/1v2 Class D Monoblock Subwoofer Amplifier Specifications:
  1000/1v2

Rated Power:
1000 W RMS @ 1.5 ohm - 4 ohm (11V-14.5V)

THD at Rated Power:
<0.05% @ 4 ohm

S/N Ratio:
>95dB below rated power (A-weighted, 20 Hz - 20 kHz noise bandwidth)

Frequency Response:
5 Hz - 250 Hz (+0, -1dB)

Damping Factor:
>500 @ 4 ohm / 50 Hz


According to the chart your amp is only stable down to 1.5 Ohms, so running at .75 Ohms the noise you are hearing is the amp clipping (running more power than it can handle at low ohms)
I would suggest wiring it in series, or you could adjust the gain on the amp until the popping goes away.

Hope this helps.

I have two Jl 13.5s w7 they only pop


There should be no need for a series connection. The outputs on the amp are parallel inside the amp, requiring you to only connect the speakers separately to the amp. With two 4 ohm speakers, you will achieve a 2 ohm output [(4x4)/(4+4)] and be within tolerance.

The Low Ohm light will also illuminate in the event of a short. Check your speaker wiring, looking for any positive leads touching negative leads or for any leads that may be grounded to the chassis of the vehicle.

Jl audio 500/1 amp low ohm light at high volume


I would try running the subs in parallel. Pos to Pos Dual Voice, Neg to Neg Dual Voice. Then Run + to + stereo - to - stereo on both channels.
So you have + and - running to one channel and + and - running to the other channel.
Also your LPF filter could be set too high.

Sunfire Mk II hum (different from greekboy post)


I had this issue a few years ago and the power cable from one of the inner terminals had come loose. It was still touching but whenever the sub would really pound it would jump off the connection and then reconnect causing it to hum. It was the most annoying thing ever so I finally pulled off the amp plate (super easy) and you could clearly see the loose wire. I had to use a good soldering iron to put it back on since it's a pretty fat wire. If you're not under warranty anymore then pop the back off and see if that's the issue.

JBL d110 /w no sound output


There is a standby indication that activates after 10-15 minutes without any input signal. I suspect that might be what the red light is telling you - no signal.

Loud hum from a loosened cable is normal as hum usually means there's an ungrounded connection somewhere acting as an antenna and the amp is doing its job to amplify what it thinks is a signal, in this case 60hz stray ac current is being sensed nearby. It's a good sign that you get hum from the sub because that means the amp is alive.

Avoid manipulating cable connections with the Sub or Receiver turned on as you could introduce a static spike that could harm any connected equipment.

Are you certain a bass signal is making it into the sub? The complexities of modern AV receivers vary in how you configure them to direct LFE to a sub. Bone up on that end of the chain.

Or, just hang a CD player on the Inputs of the sub and play something with a reassonable amount of Low Frequencies.

>>>> Be advised that this way of testing has NO VOLUME CONTROL because amps without volume controls always operate at maximum gain, relying on your external controls to attentuate it (hence, the loud hum from a loose cable); so choose a track that eases into the loud parts with some quiet parts up front and BE READY TO PAUSE THE PROGRAM AT ANY SIGNS OF STRESS. <<<<

A living sub will produce only muffled rumble in the absence of other speakers producing the higher frequencies which carry the intelligence of the signal. If that works, back to the receiver for settings. If not... sigh.

-----

For hum problems, even those you cause yourself:

Disconnect all inputs to see if that helps. If it goes away start with the signal cables and add in things until it comes back.

Sometimes the reversing the orientation of the AC plug can help with hum. Or it could be something like a loose or high resistance connection internal to the sub. 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.
