Status: offline 		Well i had 2 kicker 10's in my truck on a sony xplod 1200w amp. i took them out of the truck box(too loud) and put 1 10 in a regular box that fit perfectly behind the console in the foot. It worked fine for the first ten minutes in the single box until i pulled off the side of the road to move it and when i opened the door, i saw a spark. i think it was from the amp but the speaker wire was close to it and may have been it. idk. the amp was turned down to keep from blowing my speaker and now it want play my other 10 either. btw, the amp still lights up, if that helps. Do you think it blew, or what??

thanks.

Status: offline 		Sounds to me like the amp is in protection mode. I got this information from a car audio forum that I'm a member of.


One of the more confusing things with a car stereo can be when the amplifier goes into protection mode. One minute it's working and the next minute it's not. Here's a brief troubleshooting method that will hopefully help you if your amplifiers ever go into protection.

1. Try to determine the cause. Amp's can go into protection mode for several reasons. Knowing what happened before it cut out can help determine how to fix it. Did the amp not work as soon as it was turned on? Did it happen after blasting for hours (may be thermal overload and it needs to cool)? Did it cut out after you hit a bump (a wire connection may have come loose)?

2. Tear it down. Get the amp down to it's most basic state. Remove all of the speaker wiring and RCA wiring and leave only the power, ground and remote leads connected. If you still have a problem in this state then either your amp is defective or you may have an installation problem such as the amp touching metal.

Remember that an amplifier should only be connected to the vehicle through the power and ground terminals. Mounting the amplifier to the metal of the vehicle, including putting the mounting screws into metal, can cause problems for your amplifier. Always mount the amplifier to a non-conductive surface. An easy way to accomplish this is to mount the amplifier to a wood board and then mount the board to the vehicle.

3. If the amp is OK in this torn down state keep adding the other wires back on until you find what causes the problem. Add the RCA cables first. Then add the speaker wires one at a time. If the speaker wires cause the problem then they are probably touching metal. Check to make sure that a speaker wire isn't being pinched somewhere between the amp and the speaker. Also check that the speaker wire or speaker terminals aren't touching the vehicle metal near the speaker opening. Rear decks and door panels can easily touch unprotected speaker terminals if not properly installed.

If the problem starts occuring when you connect the subwoofer wires to the amplifier you may have your subwoofers wired at too low an impedence. First check the specs on your amplifier to make sure what kind of loads it is stable under. Then go here and check the wiring configuration to make sure that your load is not too low:

If you believe your amplifier is defective contact the manufacturer first. Many have flat repair rates that are very affordable and cover parts and labor. However local repair shops may be cheaper if it is just a small repair. Compare the manufacturer's repair rate to that of a local shop. If you don't know the reputation of the local shop it may be better to send it to the manufacturer who will have working knowledge of the amp and parts readily available.

Status: offline 		yea its in protection mode, i saw that light on but figured it was suppose to be on. i think the positive and negative speaker wires that were not hooked up to anything may have touched. i just checked and none of my fuses are blown. how can i get it off of protection mode?

Status: offline 		yea i never cut my truck off after it happened and i went ahead and took the power off of my amp. i got to thinking today that i didn't try cutting it back on and trying it. well i did today and it works fine. i still wish i knew where the spark came from!

Status: offline 		My guess is that while swapping out the speakers you may have moved the amp. I know on mine the power wire would come loose occasionally. The power wire was probably pulled out just a little and sparked with the ground. I've had it happen several times, nothing to be concerned about unless it happens on a regular basis.
