Re: amp grounding out
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.

Go over all your wiring. Make sure your power wire isn't grounded somewhere. If your power wire is touching any bare metal it will spark and blow the fuse the second you touch the power to your amp. Make sure your in-line fuse is about a foot from your battery, and make sure you have your ground wire grounded securely to the main chassis of the car/truck and that it is either same size gauge as your power or even a little bit bigger gauge. Also make sure no strands of wire from your ground or power wire are loose and reaching over touching the other where you plug them into the amp. If the ground and power touch eachother they will blow the fuse and possibly cause permanent damage to the amp.
your inline fuse wouldn't blow if there was just something wrong with the amp. the amp fuse would blow if that was the case. something is faulty with your wiring. you probably have the wires touching somewhere or are in the wrong terminals at the amp or on the wrong battery terminal. or your power wire is grounding out somewhere. its not the amp. its your wiring
Are you using the correct fuse? if so,
more then likely, you don't have a good ground. Try grounding to something else that has more direct connection to your frame. If that doesnt work, try getting larger power cables.
I had the same problem with my 2500w xplodes all I had to do was get a thicker cable for the ground and battery connection. What was happening, was it was needing more power then the wire and fuse could handle, so it would blow the fuse, since the higher you have it, the more power it needs to feed the watts.
I would try grounding it directly to the frame on a good part of the frame before spending another $70 on new power cables though.
1. Start by undoing your ground. 2. Use a jumper cable to hook up the ground to the battery ground. 3. Install fuse and test.
If it continues to blow you have an internal amp problem.
If it fails to blow a fuse you have a problem with the chassis ground.
If it is a ground issue you can chase down the various ground straps and clean the connections or you can run another ground cable to the chassis (body) ground to the battery to reestablish the connection.
Here are the troubleshooting steps for fuses blowing.
1) Remove all wiring except ground, power and remote and see if the amp powers up without blowing the fuses. If it does, the problem is in the input cables or speaker wiring.
2) The use of loudspeaker impedances below the recommended minimums will cause the amp to draw excessive current - check.
3) A shorted or grounded RCA cable may cause the fuses to blow - check. 4) If an amplifier fuse blows continually, with only +12 volt, ground and remote leads connected, the amplifier is probably defective, most likely shorted output MOSFET's. In this case the amp needs professional repair or replacement.
ok, always use ground and positive from speakers to the amps +/- . Make sure the amp is not grounded. Some amps are made of metal and will ground itself. When ever any fuses pop, this means that something somewhere got grounded. If using metal srews to mount amp that has a metal casing, chances are you will pop a fuse or two. Be careful ajusting the speaker wires with a metal srewdriver, I've done that alot. "POP"
It may not be your amp at all, disconnect the power wire from the amp and then try a new fuse. If it still blows you have the power wire grounding out somewhere, if it doesn't then it would have to be the amp.
the wire from your battery is blowing fuses? and you are using 20-30 A fuses? mine has a 100A fuse..look into getting new wire plus my wire is 4 gauge.., 1600 watts is too powerful for a 12 g wire and a 30 A fuse
Sounds like the amp is shorting somehow. You are obviously shorting out somewhere between the battery and the amp. Are you sure you grounding location is a good one? is the fuse blowing only when you turn the stereo on? Something is not hooked up correctly.
If the fuse at the battery is blowing then it's a short.
If the fuse on the amp is blowing then its probably a bad amp.
