For that amplifier, it is recommended that you are driving a 4 ohm load. It can drive a 2 ohm load, but will produce more heat and shorten the life of the amplifier. Is the subwoofer a single or dual voice coil? You'll want to make sure that you're not running below a 2 ohm load or you'll always go into protection. Also, try disconnecting the speaker wire completely from the amp so nothing but power is connected. If the amplifier is still in protection mode when no speakers are hooked up, then the amp is bad and will need repair or replacement.

All I did about the "HEAT" was add internal fans and both my autotek's run 2ohm all day no problems, I have 2 of those amps by the way.

Sony STR-DE185 receiver powers up, but then goes into protect mode. what does protect mode mean and how can I get it off protect mode?


"Protect" is what it does when it senses a dangerous condition.


Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a possible root cause for intermittent shutdown.

When i turn up the volume my amp shuts down i turn it down and it comes back on. I have a crossfire vr1000d what am i doing wrong?


Hi,
Is the protect light in your amplifier turns on when it shuts down? If yes, then your amplifier lacks voltage. The reason why it goes on protect mode is, the amplifier is needing an amount of voltage from your car, since your car cannot provide that amount of voltage your amplifier is not getting anything, instead of getting voltage to produce watts its getting minimum voltage & producing heat, to save itself it goes on protect mode so the incoming power shuts off & cools the amplifier.
Example:
Your on vol 40, amplifier is working fine, when you turn it up to vol 50 your amplifier shuts of, then you put it back to vol 40 & your amplifier turns back on.
At vol 40 your voltage is 12v or above. but in vol 50 your voltage drops to 11 & below.

Check your battery or alternator if they are giving enough voltage


Hope this helps your inquiry. Have a blessed weekend.

Amps shut down due to, A: Short circuit, B: Overload. C: Over Heating. It is possible that the Output devices inside the Amp. get too hot during use, Are your speaker "Leads" "Big" enough?

My amp keeps going into some safe mode and red light blinks and stops base to my sub. I have it hooked up to 1 15.4 Orion HCCA.


The "safe mode" on your amp usually kicks in for two reasons - the ohm load on the sub is too low for the amp (presenting a "short" to the amp), or it's going into thermal protection because the amp is too hot. From your description, it sounds like there's a short in the wire, the sub's ohm load is too low, or the sub is partially blown.

If you have another sub or speaker, connect it to the amp's output and see if the amp still goes into protection mode. If the amp goes into protection with a known-good speaker, then there may be something wrong with the amp's power supplies. If the amp works properly with another speaker or sub, then I would check the sub that's causing it to short out.

You may also want to check whether or not the amp is over heating by just touching the amp when it goes into protection. If it's just warm, that should be ok - if it's hot, then it might be working too hard. In this case, you may need to check the input voltage (12-14VDC) and the size of the power and ground cables. If your ground isn't properly connected, it can cause weird problems like over heating, shorts, erratic behavior, etc...

Hot Receiver Goes Into Protect Mode & Switches Off!


The protect mode is a result of the heat not the cause. What is likely to be hapening here is that the amplifier is seeing to small a load. The amp is designed to work with speakers that are either 4ohms or 8ohms in impedence. An impedence load of 2 ohms will work but will cause the amp to work really hard and generate extreme heat. The solution to this is usually to locate speaker wires that may have crossed or frayed and shorted against each other. Were the amp to have a problem, you would not likely be able to get sound at all.

There is a possibility that the driver circuit within the amp is out of whack too. This could cause an imbalance internally that would also generate excessive heat. This is extremely rare, as this type of offset generally is caught by the protection circuitry.

Check the speaker wiring first. Next, if you have 2 speakers connected, only use 1 at a time. It is possible that there is a defect in the speaker where the laquer on the voice coil has worn away and the coil is shorting to the speaker frame intermittantly. If this is the case, the unit would behave differently depending upon the level of sound and the type. Also, it is unlikely that 2 speakers would have this problem. Disconnect 1 speaker and run the system for a while. If it works well, try the other. If a speaker is the problem, one of them should show the failure.

Please keep us posted.

Thanks,
Dan

AMP


If the amp gets hot or goes into protection with no input signal and no speakers/wires connected to the speaker terminals, the amp likely has shorted output transistors. It's not a complex amp. Any reputable shop should be able to repair it.
