Question about Jl Audio 500/5 Car Audio Amplifier
My amp heated up and quit putting out sound but it still gets power to it. you have any idea what it could be?
It is probably in the "protect" mode. When this happens, the amp will have power going to it and seem to be turned on, but no sound. Many amplifiers have a LED that is normally red and it lights up when in the protect mode. Check all the LED's on the amp and see if one of them is for the protect mode.
When an amplifier goes into protect there are usually only 2 reasons for it.
1. A bad speaker
2. A channel blown inside the amp.
Disconnect the speakers to the amplifier and see if it makes the amp come out of protect mode. If the amp has an LED to indicate when it is in the protect mode, this LED will shut off, and sometimes they have a relay inside the amp that you will hear click. If you hear the click sound form inside the amp after you disconnect the speakers, you probably have a bad speaker. Take yours to a service center and ask them to check them for you, many shops will do this for free, I know that my shop will do it for free, so I assume that many others will also.
If the amplifier has a blown channel, you need it serviced. There is no quick fix for a blown channel. If you have a multimeter I can tell you how to check some of the components inside to verify if it has a blown channel. Let me know if you are able to do this and I will give you instructions on how to properly test the components. If you do not have a multimeter, there is really no way to figure out what components are bad. Your only choice would be to take it to a service center for repair. They can give you an estimate of what it may cost before you are committed to paying for a repair. Most car amplifiers will cost about $100 to $150 to repair a blown channel. It just depends on how much damage there is, and the rates of the service center.
I hope this is helpful, and if so a good rating would be appreciated. If you need to communicate more with me to determain what the problem is, please wait to give a rating until we are finished. That way I will not get an undeserved bad rating. By the way, the only rating that is good (meaning that it doesn't lower my over-all rating) is a FixYa! rating. The "Helpful" and lower just bring my rating down. After all, the only reason for offering this free help, is to get a good rating.
