Protection light won't stop blinking/ Subs don't work

Just installed this amp into my car. I know that nothing's blown because it has worked for a few minutes. But now everytime I turn my car on the protection light justs blinks and I get nothing out of my subs. Wiring is all good, everything is brand new. Any ideas would be helpful.

    Read through the troubleshooting guide, it may have something to do with the RCA's or Speaker wires. Tested this by taking out the rca's and speaker wire (sub amp powering 2 12's) when I turned my car to aux, instead of blinking the protection light was just on, no blinking. I then re-attached and they started blinking, took them off again with it on and it stayed blinking, weird. Also, put a voltmeter across the amp (power and ground) when the prot. light blinked off it showed 12~ volts, when the prot. light blinked back on (protection on) the voltage would drop anywhere between 1 and 3 volts, going as low as 9.5~ volts. Does this help? Is there more info that I could get that would be helpful?

The amp probably has shorted output transistors to eliminate other possible causes, read through the following page. Let me know if you have any other questions.

Boss 5500 watt amp stays in protection mode

The amp is going into protection mode because one or more of the output transistors is fried inside. You want to check for resistance on all the outputs. I repair these everday. Either have it repaired or do it yourself. I buy broken amps and I also repair them. Let me know if you want to sell or repair or want instructions on how to repair it.

The green light and protection light on my 1100d constantly blink and the interior lights in my car blink in sequence with the lights on the amp and I get no sound out of the amp and sub setup. What could...

Sounds like you have an issue with the amp, the install, or possible blown subs.. check, test and if all else fails get the amp serviced or get a new amp.
A good car audio shop can also help you check it over.

JBL amp, worked fine untill 2 days ago. protection light on..

might have roasted your speakers voice coils a little which may be sending the amp into protect mode throw a speaker on it that you know works and if it doesnt trigger the protect circuit then you probably have a blown or almost sub.

Amp powers on, no sound from subs

the output is blown. It is in need of service.
There are many different ways that an amp can fail but the two most common failures are shorted output transistors and blown power supply transistors (< those are not blown). There are several types of protection circuits in amplifiers. The most common are over-current and thermal. The over-current protection is supposed to protect the output transistors. Sometimes it doesn't work well enough to prevent the failure of the output transistors but it will work well enough to shut the supply down before the power supply FETs are destroyed. If the amp remains in protect mode, goes into protect mode or blows the fuse as soon as the remote voltage is applied, shorted output transistors are almost certainly the cause.

Red LED "Protection Light is on" What is the problem

The red light means the amp is in protection mode. A few things can cause protection mode..... First disconnect the subs completely from the amp, and turn it on, if it powers up you have blown subs. Also try checking the main power wire at the battery...sometimes the current your meter is seeing is backfeeding from the remote wire, so your main power line could be blown at the fuse under the hood. hope this helps

Amp not working correctly goes into protection

Disconnect the speaker wires from the amplifier and see if it still goes into protection mode. If it still goes into protect with the speakers disconnected, there's a problem with the amp; if not, you may have a blown speaker or a shorted speaker wire.
