Disconnect the speakers from the amplifer, and turn the system on again. if the protection light still is active even without the speakers hooked to it, then it is most likely that you have a blown transistor in either the power supply section, or the output section.

Either way, your amplifier will need to be serviced.

Well i was driving one day and my subs just whent out so i bought brand new wires and hooked everything up but the power protector light turns red whenever uu turn it up past volume 10 i really do not know...


It sounds like your amp is going into protection. I know it's frustrating, but this is actually a good thing. If you subs you have are drawing too much power and the amp can't keep up, it will shut off instead of melting the board. Usually, the protection mode only last a few seconds. The user normally turns the music down that the protection shuts off and the music plays again. I recommend looking at a larger amp for your subs, if you are going to play them that hard.

I have a red light right next to my ground remote and power wire Connecters and it comes on red and then turns off what's my problem


Ok, need more information, but I will tell you what I am assuming. I assume you are talking about an amplifier. Does it work after the light goes off? If not, It sounds like your amplifer is either going into protection, or that your amplifier is malfunctioning.

If your amplifer is going into protection, you need to check wiring. Most amplifiers go into protection if they sense an amperage anomoly (ie. fluctuating high and low, or overload). This would be a good thing because it's protecting your amp. But it's also frustrating, because now you have to find the problem. If your issue is wiring, I recommend starting from scratch. It's a pain, but will save you the frustration of checking every little thing and there a lot of things to do with the wiring. Always use a multimeter when checking for good ground placement. This tends to be a leading problem with amps shutting down. Also, inadequate guage wiring can also be an issue. Happy Hunting.

Kenwood kac-749s amp power indicator flashing red. what does this mean and what can fix it?


Either there is a short in the in the amp or hopefully just the speakers or wires going to the amp. disconnect any speaker input output and turn your amp back on(you will only have power, ground, and remote wires plugged in at this time) and if the red protect light goes away, then there is a problem with the input/output speaker wires, this includes your RCA's. If it's still flashing red then there may be a stray wire shorting to the amp in the speaker outs, other than that your amp may be fried. By the way, if it works without any speakers connected, including RCA's try connecting one component speaker at a time starting with your RCA's(if using them), speaker in, then speaker outs. If it turns into protect mode, note which speaker/RCA it was and replace or repair the short.

My kicker dx 500.1 and my xpliod tens worked for all of ten seconds before the protect light went red then green keeps doing that


You are running more then 1 speaker on a 1 channel amp. You need to verify how many ohms your subs are, and what ohm you are wiring your subs to run at. Your amp is only capable of running at 2 ohms.

Here is a link to figure out how to wire them correctly.

Here is a link to your amplifiers specifications.

I have 12 volts constant on my power wire coming from my battery but when I connect the p.cont. wire to the amp the voltage drops out. The green indicator light comes on for a split second then fades away...


Your P.cont is not hooked up to a correct power source... Make sure that you dont have it possibly hooked up to the power antenna wire by mistake. The p. cont. (remote turn on) should always send constant power one the key is turn on in the vehicle.

No sound from subwoofer Solo Baric L7


check the resistance of the sub with a digital multi meter, make sure you dissconect the sub from everything before you check the resistance, if your sub is supposed to be 4 ohms than it should be between 3-5 ohms, if it is under 1 that the sub is blown, while the sub is dissconected from the amp, turn the system on, does it still go into protection?

Basslink Powerlight comes on then fades quickly


check to make sure your remote wire is hooked up to your amp turn on that runs straight out of the stereo not your power antenna also make sur you have a clean ground(no paint or rust) and also check your connections make sure you have a strong connection to all wire hook ups.......you should check to see that your remote wire has no tears in it or small rips or cuts because that can interrupt your current to and from the amp and radio

Amp is going out.


Have you tried replacing all of your fuses? If that does'nt work check your ground........ I would check all your connections also could be a connection shorting out causing your red light to come on.

Subwoofers won't work and they are brand new


Hello,

I've got a pair of these MTX's subs powered from a Fusion 450 watt 2-channel amp. For the price, they are great. By the way, they are 4-ohm.

My first suspicion would be that something in the first incorrect wiring damaged either the amp or the subs. Can you explain specifically what the "installing the subs incorrectly" means? Was the amp output shorted out at any time or was it operated without a load? Either of these conditions will fry an amp and sometimes, the protection circuitry doesn't work either.

First make sure that your amp is still working. Check both the primary power fuse, usually located near the vehicle battery, and the fuses on both sides of the amp. Make sure that when you turn the system on, the power light comes on steady (blinking is protection mode). Test your subs one at a time on a speaker output.

I have an older red sony xplod 500w 4ch amp. the power/protection light is glowing red. what does that mean and how do i fix it? I have no sound.


The protection light comes on if the amp overheats or if the speaker outputs are shorted.

Turn everything off and check all of your speaker wires for shorts. When you locate and repair the short, the protection light should go out and your amp will work normally again.

Hope this helps!
