Amp heats up quickly, melts fuses and shut down after a while

Hello, We just installed this amp and all of the channels work fine but in a short period of time and even w/o the sub channel connected, the amp heats up very quick and it melts fuses ( it burned one fuse, but the other one melt but continued working). And after a while it turns off. Hope someone can help me. thanks, Vic

It sounds like the power cable you have may be too small. If you're using an 8 gauge for both the power and the ground, try switching to a 4 gauge for both.

Amp's blue light is on but does not seem to send power to sub

It is possible that the set has gone into an error shut off. Please disconnect the power and allow it to cool off. remove the sub woofer connections if the amp does not turn on again. check for any short in the coils. reconnect the sources once again , making sure that the source is coming into the amp. If there is still no output, remove the cover and check if the main amp is shutting off due to any short in the output. You will need to confirm this out as you had run this a little too much in heat. replace the shorted mosfets if confirmed. hope you get this right. Good day

Remote wire heats up and starts to melt.

sounds like the remote wire is shorted somewhere in it and needs to be replaced. You also need to be sure you are hooking it up to an ignition switch and not a constant I usually use the radio fuse in the fuse box.

When i started to plug my battery in my amp made

you have blown the actual filters that make the sound. a amp is basically a filter with the same filters on both channels on each side of the inside of the amp - channel 1 and channel 2, that pop was in the heat sinks of the amp usually. if you have replaced the fuse in this amp and you get no on light, the internal amp is in need of repair

I turned my car on and when the amp turns on one speaker pushes out and the other pushes in and stay like that and dont produce any sound. i checked the wires and fuses and everything is correct but i cant...

Hello mikhail_1994,

I'm assuming that the amp was installed and was working properly.

It sounds like the output is shorted. The CH450 may be operated as a 2-channel amp or both channels can be bridged for mono powering subs at an impedance of 4ohms or more.

I'd test the sub voice coils and then test each channel of the amp separately.

Hope this helps.

My 800 watt kenwood

Sounds like you shorted out the main power wire somewhere and killed the amp. Is the amp on the fuse intact or blown? Do you have 12 volts at the amp? check you connections and see if it helps.

Kenwood 7202 Amp that is blowing fuses

If your speakers are wired for an impedance below 4 ohms mono or 2 ohms stereo, that would make it shut off. If you have a speaker wire shorted to ground, it would also cause the amp to go into protection.


If the speakers are not the problem, it may be shutting down because the voltage at the amp is dropping too low.

Amps protection

No but eventually you will melt the varnish coating the wires on the voice coil and will cause the voice coil to fall to short and could possible blow the Amplifier. and definately ruin the speaker.
