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.

Rockford R-1000-1D going into protect. Hooked up to two P3D212's. Wired at 2 Ohms. Not to mention checking and double checking and triple checking all the wiring to and from the amp. What could be...


  • First of all this amp is not "bridgeable" per the data sheet and Rockford Fosgate's. Short story your overloading the amp. You may be able to physically run it "bridged" but it is going to kill the amp. No doubt the set up will pound... itself right into the amplifier graveyard. The amp does not have to get hot to go into protect mode, it only needs to sense a malfunction as well.
  • Something else to. The speakers are rated at 2 Ohms as well as the amp (2 Ohms) That means the least Ohms you can but to the amp is 2 Ohms. When you bridges them 2 speakers you drop it down to 1 Ohm. Unsatisfactory for the Amp to function properly.

Well, check again for lose wires and make sure it is grounded good and let me know what you find, Make sure you check ALL of the wires.

I will be more than happy to help you when you get back to me on this.

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? Is you Power Positive wire the same, Also as you say, Check your Earth. Sometimes a Fan on the output devices helps.

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...

My nitro bmw-486 amp is in protect mode how can I


Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty De .A thumbs up would be greatly appreciated if this answer is helpful to you. nitro-bmw-486-amp-in-protect-mode-lv2kkrmxrai4iihdvw4m3np2-1-0.jpg

My amp goes into protection mode when i turn on my car. It gets hot too. I had 2 kicker 12" l5's and blew the subs with that amp, could i just have a simple problem with the amp? What are all my options?


Protection LED on, no output? Amplifi er is very hot = thermal protection is engaged. Test for proper
impedance at the speaker terminals with a VOM meter (see the diagrams in this manual for minimum
recommended impedance and multiple speaker wiring suggestions). Also check for adequate airfl ow around
the amplifi er. Amplifi er shuts down only while vehicle is running = voltage protection circuitry is engaged.
Voltage to the amplifi er is not within the 10–16 volt operating range. Have the vehicle’s charging and electrical
system inspected. Amplifi er will only play at low volume levels = short circuit protection is engaged. Check
for speaker wires shorted to each other or to the vehicle chassis. Check for damaged speakers or speaker(s)
operating below the minimum recommended impedance.
No or low output? Check the balance control on source unit Check the RCA (or speaker input) and
speaker output connections.

Goes into protection mode for no reason


if the amp is powering on the sub and playing and then turns in to protect mode it could be the amp is getting hot and its kicking into protect so you wont fry the amp

Disconnect all of the speaker wires and signal cables from the amplifier.

 

If the amp still goes into protect when you power it up, the output transistors are likely shorted.

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.
