Question about Car Audio & Video
Grounding out in amp and blowing fuses
If the amp is blowing fuses, you could have one of several problems. The only one of those problems you could fix yourself is if you have a shorted speaker. A speaker that is shorted in the voice coil can cause the fuse to blow. To check if this is causing it, dis-connect the speakers and then turn it back on. If no fuse blows there is a good chance that a speaker is shorted, take the speakers to somebody or someplace that can check them properly. If the fuse still blows with no speakers connected, you have an internal problem in the amplifier.
If the fuse blows before you even turn the amp on, you have some shorted components in the power supply. If the fuse blows after the amp gets turned on, you have some shorted components in one or both of the output channels.
Unless you have some experience with electronics and have the proper tools to troubleshoot electronics, there is really nothing you can do yourself to fix the amp if it has internal problems.
You should take it to a repair center and get an estimate for repairing it, that way you can decide if the cost of the repair is worth the price of the repair. Sometimes it is better to just buy a new amp, but you first need to know what it will cost for repairing it. There is no way to tell you how much it will cost to repair without having the amplifier in front of me and troubleshooting it to see exactly what is wrong.
If I can be more help let me know, I have been repairing car and home audio equipment for almost 18 years and can offer you good honest advice.
