Question about MA Audio HK2000D Car Audio Amplifier

Driving in first gear

I was driving up my driveway in first gear in my caddy with my system on and i heard a humming sound in my subs and then my amplifier stopped. now the status light is red instead of green and it does not play at all. i have full power from the battery and the amp fans are still working just no sound. r.c.a.'s are good and wires are 4 gauge-all new. its a fairly older model either a 2000, or a 4000hk ma audio. its been to the shop once before and they "claimed" to have fixed it... they did half way, but now this... help if you can...

Your Amp is in protect. Disconnect your subs and turn it back on. IF the led goes back to green the you have a blown Sub and it will need to be replaced. If the amp stays in protect even with the subs removed the the amp is toast.

1994 Buick LeSabre has clicking noise in steering column when reversing.

Could it be coming from the dash??? That car might be old enough to have a speedo cable. Another thought, I know some Caddys that had an automatic park brake release. You had to put it in gear for the Park brake to release. Hope that helps.

Gear knocks when shifting

please do say ,exaclty what knocks.
is this heard or felt or both.
is the sound inside car or outside,
there are 3000 parts in newer cars.
so direction to noise is complex , to the extreme

my guess, is car has a M/T tranny , a STICK, say so.....
and you are shifting and you mean the gears grind?
knocks , is something engines do ....
so you shift and all gears work? no not
you can shift up or down, so do all gears work or just 1 fails
and if fails tell use what you were doing.
driving on the road.?
or backing out of the driveway?
what?
give is CONTEXT. tell what you did, and what car did wrong.

Benwin 5.1 surround sound system Humming loudly without anything pluged into it!!!

It is sad your having a problem with your
Benwin 5.1 surround sound system
If humming can be heard on all speakers, then it could probably

be on the power supply.

If it is only on the main SUB unit, then it could be the amp itself.

But check for power supply capacitors that supplies voltages to the

amps.Check for amp output DC voltages too.

Medium humming noise when backing up at low speeds

Probably rear brakes. Clean them up or get them looked at and try again.

Humming sound in subwoofer after it's been playing for a while

It sounds like you are describing an earth loop problem. I won't go into detail in this post, but try an isolation test first. disconnect everything from the reciever except the sub and try connecting say a BATTERY powered mp3 player or cd player to minimise connections to the electrical mains earth. you could also isolate things by taking your sub to a friend's house and trying it on their system.
If it is an earth loop use a process of elimination to find out which two pieces of equipment causes the earth loop. then apply filtering.
you can buy earth loop isolation transformers for about AU$26 and I've used one on my sub myself. Theyhave RCA (phono)plugs on each end and they connect inline with the signal cable to the sub amp.

as for the thumping sound it might be the speaker protection circuitry cutting off the amp to protect the subwoofer speaker from damaged. This might be triggered if the earth loop sound is causing the sub amp to overload and clip.

Failing this there might be a dried out overheated electro capacitor in the amp circuit causing the hum. Hav a chat to your local electronics person, who should be able to spot it!
Hope this puts you on the right track
Happy Hunting!

Bought a used Martin Logan Dynamo subwoofer a couple days ago and have a very loud hum when the ac cord is plugged in, even if the speaker is not connected to an audio source. The "hum" can be heard in any...

Neither the amp or the sub have grounded power cords.

I have discovered the ML Dynamo takes about 30 minutes to switch to standby in auto mode.

With speaker level inputs connected to the Onkyo A807 amp, both units powered from the same wall outlet, Dynamo sub on Auto, the sub hums for about half an hour after the Onkyo is switched off, then the sub goes quiet. Not so good.

I connected a bonding wire between the two units on 3_7_09. If I smoked some old audio gear I could just look at that as an opportunity, right?

Works fine. Now I have the ML powered from the wall and working normally.

Sounds like you have a faulty Drive/ Eject door motor, Snapped drive belt if a noice can be heard or the Motor driver chip has malfunctioned.

When you press eject listen for a noise like a small humming from the dvd drve part, if there is a hum then more than likely your belt has broken which is inexpensive but if nothing can be heard then its likely the motor or Driver Chip. The motor can be easily replaced if found on an auction site.
