Recently, when I attempt to switch my Insignia NS-R2001 Stereo Receiver out of standy by mode after turning it on (it is automatically in standby when you turn it on), it switches back to standby mode after a few seconds. I have also tried using a different amp and that one also went into protection mode. For those who don't know what a blown fuse looks like, the one on the left below is blown. I dont know what the problem is? Amplifiers are often designed to go into “protect mode” to avoid further damage to internal components. Try switching the right and left at the amp and see if the problem moves to the left input with it. - Testing the voltage on the remote wire to make sure it is strong enough to turn the amp on - normal (14.4V) - Making sure that the power cables are … The remote turn-on has occasionally become loose and I figured that's what had happened. Since the meter leads are not long enough to reach the grounds at the battery or trunk over the long run of the power wire, you need to scratch the paint/primer/undercoat to bare metal at each point where you need to check the voltage. Noob here and first timer poster, so any help is great! If it doesn't go into protection with no speakers connected, I suspect that the speakers have ben damaged, especially if they're small. Sometimes, a VERY brief drop in voltage (too short to be seen on a standard multimeter) will cause the amp to shut down for a short while. If the voltage at BOTH the B+ and remote terminals is low and your vehicle's battery is not low (check the voltage at the battery with the multimeter), touch the black lead to a known good ground (a point scraped to the metal on the floor pan of the vehicle) and the red lead to the ground terminal of the amp. Generally, the power light is green or blue and the protect light is red but on some amps, the protect light is green and the power light is red. It was working great until randomly the amp went into protection mode. It's important that you leave your head unit on during testing so that the remote line will have voltage on it, the amplifier will be on, and the amplifier will be drawing current. This is common on older Alpine amplifiers. If the voltage remains near or above 12v but the amp still goes into protect mode, disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. Most meters will not read to 0 ohms. If the amp is OK in this torn down state start reconnecting wires until you find what causes the problem. I have yet to open the amp but I’m wondering if it would be a simple fix? Clues to a Bad Connection: .

I also plugged in my phone with a jack to rca converter and I get the same result. If everything there checks out, then you will have to … I have the power and ground secure, and the remote wire runs off the fuse box up front. and it was a bad ground at the amp. 4) Check the grounding is solid. If you read something less than 1v, the transformer is likely OK. Important! Not many amplifiers will illuminate the protection light when the fuses are blown but a few will so you need to check this. Sometimes it will make it through a whole song without doing it, sometimes it stays in protect for the majority of a song. power my subs will make popping noises and the amp goes into protect. If the amp goes into protect with no RCA or speaker cables connected to it or if the amplifier blows the fuse AFTER remote voltage is applied, the amplifier likely has shorted output transistors. If the power light blinks then goes off, the amp is either going into protect mode or there is a bad connection in the power supply wiring. Sometimes the voltage will only drop when current is being drawn from the power source. If you're using a mono amp and have only one pair of speaker wires, you'll need to disconnect all but one speaker from the other end of the speaker wires. Bachelor's Degree. All these wires are fully connected and I have no problems with this. Or if its something much harder to fix. However, when I only connect the left speaker, the receiver goes in protection mode right away when a peak of high volume is sent out by the receiver. Sounds like the ground at your amp and the ground at your HU are different, and when the RCA's try to equal out the voltage it throws it into protect, because the amp sees a huge voltage on the input. The model # is XM 554ZR. I installed my amp with the rockford 4 gauged amp kit. But as soon as I plug in 1 RCA cable it goes into protection. Problem: Amplifier goes into protect. Fuses - Open But Not 'Blown': Maybe your gain is set too high. Sucks… John Regalbuto. The first thing you need to check is the on-board fuses plugged into the amplifier (if it has them). Amp goes into protect mode!! 140 dB . Hey, I had my amp working for a few minutes with all the gain and everything set to low.

To know how low your meter reads at 0 ohms, touch the leads together for 5 seconds. If the shield ground of the head unit is OK, the amplifier could have one of several problems. I have a pioneer gm-5500t I checked all the wires and connections and made sure I had a clean ground. I removed the speaker wire to see if its the speakers and its not the light still shows red. I have a 200 watt amp in my car, and everything worked fine. It is a much more powerful amp than the sub, the amp is 850w rms while the sub has a tolerance of 600w I thought setting the gain all the way down would allow it to be used with it. Such problems usually result from having the subwoofer positioned at a different distance from the listener than the other speakers in the system. Senior Engineer. Using the demo should help you to better understand where you'd lose voltage when there is a break in the circuit. My fuse running from the battery power wire blew today so I had it replaced. If the fuse holders are melted, you need to have the amp checked by a technician to determine why they melted and to determine if the fuse holders are usable. PROTECTOR as soon as I turn it on. You need to power up the amplifier and measure the voltage on the shields (shiny outer metal ring) of the RCA jacks. The amp started to go into protection as i was setting the gains,i thought maybe the amp was detecting clipping that i could not hear so i decided to turn the gains down a bit. If your amp has a “protect” light, and it’s on, then chances are good that you have a faulty speaker, subwoofer, cable or another component. All my wiring is solid and ground looks good. New member. If you read more than 0.01v and the amp is at idle, you may have a bad ground. Once I had a chance to check, I found that the amp was going into protect mode. The same noise it makes when you turn it on. Normally, both will be above 12v. I then did the reset and listened for 2 hours without shutting down. Tried the disconnect/reconnect of all internal connectors. Phase Shift: Use this button to help compensate for time alignment problems. 4. Some amplifiers have a problem with broken connections between the RCA shield and the circuit board. I have a pioneer gm-5500t I checked all the wires and connections and made sure I had a clean ground. I get so many questions about amplifiers going into protection (or blowing fuses after remote turn-on voltage is applied) that I've decided to provide a page to help determine if the amplifier is faulty or if a fault in the system is causing a problem. If the power light blinks then goes off, the amp is either going into protect mode or there is a bad connection in the power supply wiring. You will also see defective fuse holders. Then I disconnected the RCA cables and the amp turns on. RCA leads are used to feed the amp with input signal from the car stereo. Page 1 of 2: 1: 2 > Display Modes. When I only connect the right speaker to the receiver, I can play at high volumes without the receiver going in protection mode.
