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.

I Hooked up a Performance Teknique 1200 watt 2 channel amp to my 2 12" comp kickers. and before doing all this i took out the fuse. from my car battery. after everything was hooked up i put the fuse back...

disconnect the amp and then put the fuse in.if it blows,there is a pinched wire causing a short.
Also,big amplifiers like that have to be wired battery direct.
the surge current at boot up can pull 100 amps for 10 millisec.

I have a Jensen A600HLX hooked up to Rockford 12 and it keeps getting hot and cutting off. I have it mounted on the top of the box. What is wrong?

Make sure you are using the proper gauge wiring for your amp.

Is the amp set up in bridged mode? What is the impedance (Ohms) of the Rockford Fosgate 12? If the impedance of the speaker is different from the impedance for the amp in bridged mode, it WILL get hot and cut off. Also, if you overdrive the amp, the same will happen.

The amp is stable :
  • 75 watts RMS x 4 channels at 4 ohms
  • 100 watts RMS x 4 channels at 2 ohms
  • 200 watts RMS x 2 channels bridged at 4 ohms
  • 300 peak watts x 2 channels bridged at 4 ohms

  • Also, what model is the subwoofer? What are the specs? Is it single or dual voice coil?

    You can most likely mount a cooling fan on the amp and have it turn on using the remote sensor wire. If the amp still cuts out, you're overdriving it.

    Good luck and keep me informed!

    I have 3500 watts of subs total of 1100 rms what size amp should

    Make shure your running thick guage wire like 2-0 guage wire to get correct power to it also and check on amp the ohm's it can handle to make shure your not running to makny ohms.

    Audio system set up

    Well one problem is you might need a smaller amp depending on how many speakers you have, 1200 watts is way overpowering for 300watt max speakers and could possibly blow them and even catch them on fire!!!! But everything else is compatable because all of your epuipment is of a newer products but if you dont have 4 guage wires or anything else make sure you get them heres a list: 4 gauge wires for power and ground, REM wire "blue is the normal color" RCA jacks, A compacitor, fuse for battery to amp to keep system from blowing up, 8 gauge speaker wire or even 12 guage to hook up from the amp to the speakers, That should be the common things you need to have a good thumpin system!!!!

    Car amp blows 12 volt wire fuse

    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

    2.0 Farad Capacitor

    The answer is yes, any amount of amplifiers can be hooked up to a cap. Obviously the more amps you hook up to it the less you are going to nodice the difference with the same amout of farads. The only thing that I am worried about is the wiring from your battery to your cap. As long as you have a decent gauge wire running back you should have no problem. And for this instance I would recommend 0 guage, you might be able to get away with 4 but I would highly recommend 0. Over all I would recommend 0 guage on all installs unless you are going small and don't plan on upgrading. I hope I could help

    Hi jimmyjames,


    How do you have the wires hooked from the sony reciever to the inputs on the mtx? 

     Sounds like your Remote wire is way too big. it should be 14 guage.  It only sends a low voltage low amp signal.


    Another thing that could be messing up the sounds is the routing of the wires.  you should have the power supply wires separate from the Audiop signal wiring.  Power should run down the Driver side and Audio down the passenger side.


    When you answer I may be able to tell you more.

    Amp not working correctly goes into protection

    Disconnect the speaker wires from the amplifier and see if it still goes into protection mode. If it still goes into protect with the speakers disconnected, there's a problem with the amp; if not, you may have a blown speaker or a shorted speaker wire.
