I hooked up a car amp and when i put the fuse in,it blew.then i disconnected the power,installed the fuse and as soon as i touched the power cable,the fuse blew again...


Hello
Some kind of dead short is there. It may be inside the amp circuit of with outside wiring. You have to find it by meter check. Contact a auto electrician and let hinm detect the fault. OK.

Old Amp blew, got a new one. Power light came on but speakers didnt work. Unhooked the amp, hooked it back up and no power. Any ideas?


Are the speakers still working? When the old amp blew it might have blown the speakers too. Are any of the wires grounding out besides the ground? I would check the remote wire too. I also suggest replacing it with a bigger (smaller #) gauge wire, its not as sensitive to interference and gives your amp a boost in actual power to the speakers. Check any fuses to see if they are blown. Make sure all the connections are tight. If no power after this all checks out then amp is blown again and you might want to get smaller speakers or a bigger amp (or better).

Toxic tx 600 amplifier


You need to get another amp for your sub. I would say if you want good quality go for MTX because I have had amps from MTX and never had a problem. what you need to know is look at the fuses on the amp if there are 3 of the 25 amp fuses on there then it should push out about 750 watts but on MTX they under clock the amp so it will push about 800 at 14.4 volts for that you will need a 4 gauge wiring kit with a 60 amp fuse in the fuse link. As far as your other amp hook up the speakers and tweeters to that but be sure to tune in down and you would need a 8 gauge wiring kit. I hope this helps you.

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.

Amp burned out


yes you shorted the output transistors and replacing them will fix your issue. inside the amp you will find three legged transistors that mount to the amps body/heat sink. replace all of them.

good luck man.

Power surge


i am guessing the car still starts, this means the battery is fine. other than that you can try checking all of the connecting power cables, if nothing is burned out then i am afraid that it probably is the amp blown out

Power Acoustik 1600 trouble


All fuses would be external. Check all of them.

If all of the fuses are OK, you probably blew the power supply for that channel (and possibly the output transistors). You'd need an ohm meter to check them.

Let me know if you have any other questions.
