SOURCE: power light turns from green to red protect mode and then there is no sound coming from my speakers

there are 2 reasons for it to be going into protect mode 1 is heat 2 is the load on it. if it is going into protect mode soon after it starts there is a problem with the speaker. if it is after it has been on for a while it is that the amp itself is overheating. hope this answers your question

SOURCE: my kicker amp goes in and out of protection, like

Thankyou for the detailed fault description..it really helps!

sounds like there is one of these 3 things wrong:

1. leaky or partially blown mosfets on ouput power stage of amplifier are leaking DC onto speaker output causing amp to go into protect..this explains any banging or clicking herd.

2. There has been damage to the internal SMPS and is going into protect because of an internal rail over-voltage/under-voltage.

or 3. you have a shorted speaker lead or sub that is bringing the amplifiers load down to less than 2 ohms..buy or obtain a multimeter and have a poke around and check all your speaker leads on the ohm setting anything lower than 1.6 ohms and you have a short...also make sure that you have correctly loaded amplifier to..alot of begginer audio enthusiats overlook this important step and cook amplifiers!!

remeber impendance ratings, have a look on google, search "impendance formulas" and study up if your unsure!

hope this helps,ben

Tc 8001 red light

on some amps there is a duel light. red and green usually. red means it is in protect mode or you didn't hook up your remote wire. if in protect mode, it could mean a number of things. did you hook it up with speakers and everything?

Hello. My Kicker kx200.4 is acting funny. The red display light on front/top of the amp is turning on for a second and then turning off, repeatedly. The light on the side (power) is also turning on, red...

the amp is a 200 Watt by 4 im guessing and its doing that because its going into protection mode unhook the subs if it stops then 1 you have a bad sub or 2 the subs are too much for the amp if an amp is rated 200w per chanel its 200 max about 75 rms or 75 normal constant power

Unit only stays on for 4 seconds then turns itself off.

This is a short or unstable ohm load. Remove all speaker wire connections to see if the amp will stay on.
If the problem goes away when disconnecting the speaker wires try this:
1) Check volume level on zone one and zone 2 if connected. If it is too high the amp will go into protect mode and shut off exactly as you described.
2) Make sure no wires are touching any other wire or the metal surface of the amp. This will cause a short and send the amp into protect mode.

Still having amp problems

Hello lilmario,

After eliminating wiring problems and possible shorts, grounds and low impedance in the speakers, most likely the amp is failing internally. A partial failure of either the output MOSFET's or the thermistor. In either case, the repair requires removal and replacement of components on the circuit board. Depending of the age and original cost of the amp, such repairs are sometimes expensive.

I'd recommend having a professional audio shop test the amp and provide an estimate for repair.

Hope this helps.

Green and red light are on my pyramid amp and its not working

It could be even simpler than that, yes an improper impedance rating on an amp will cause it to overheat, but should function temporarily until it reaches peak temp. If the outputs were blown the protect light should not light up being that they would need to work to cause the protect light to come on. I would double check all of your connections, one small little crossed wire would cause an amp to immediately go into a protect mode.
