If the fuses only blow after the remote voltage is applied, the output transistors are likely shorted.

 

According to the owner's manual, the amp should have two 20 amp fuses.

Everytime I cut it on. It cuts back off like there is something wrong with it


If you turn it on and it clicks right back off you may have a short. Make sure the wire panel does not have any straggler wires going from one connector to another. Also you may have a very weak fuse. Check the fuses in your amp and at the battery terminal. Make sure the power, ground and remote wires are solidly connected. Make sure that ground is tight. Is the deck shutting off at the same time your amplifier does? The remote wire off the deck powers that amp so if the deck is also cutting out the problem may be the deck and not the amp. If this is the case then run through the steps I listed above but with the deck as well.

Regards, Tony

3 amp fuse blows


Mark all your wires using tape or by writing it down to ensure you will be able to hook them back up exactly the way you found them. Remove all the wires from your board again. Tape off the ends so you don't "short" anything together. Identify the wires going to your outdoor unit and the wires going to your thermostat. Hook the wires up one at a time starting the with C wires and the R wires. Then hook up G. Then W. Then O. Then Y.....and any other wires you might have. Check the fuse everytime you hook up one of the wires. Remember to do the tstat and outdoor unit wires one-at-a-time also..........meaning........you will have 2 "Y" wires. Hook up only one, then check the fuse, then hook up the other, check the fuse...........Eventually, that fuse will blow again when you hook up the right wire. Then you will be able to determine the color wire and whether it is the one for the tstat or the outdoor unit. Once that is determined, disconnect that wire at the other end and re-install the fuse and restore power. If the fuse blows, the problem is in your wire. If it does not blow, it is most likely a bad control coil. More often than not, it's the wire. Look for damaged insulation and "crimps". Usually the repair can be made with simple electrical tape and/or cutting the bad spot out, using a wire nut and electrical tape, and testing it again. Let us know how you made out. If you run into another stumbling block, we'll dig deeper and walk you through it. :-)

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

Amp blows fuses


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.

Blowing of fuses


The reason your blowing fuses is the amp needs at the least a 150 amp fuse on the wire that runs to your bat. There are fuse blocks that you can put 4 40amp fuse and theres the high dollor ones that you can put all the way to 200amp. When you trun up your amp its drawing to much current for the little 40 amp fuse that you have and will blow it everytime. I recomend Running a 4 gage wire to bat and ground with same. Get you a 150 or above amp fuse from a car audio shop somewhere. anyway sounds like from what you decribed, theres nothing wrong with your amp just the wires and fuse are not big enouf to handle the current that your amp pulls.

Keep Blowing Fuses


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.

Amps


If the amp blows a fuse with no remote voltage applied, the amp has a short in the primary side of the power supply. If the fuse only blows after remote voltage is applied, the amp probably has shorted output transistors.
