Re: directed 2400 amplifier turned off and has not come...
Based on your post/description, three possible reasons:
1. There is no power going into the amp. The fuses may be good but there is no +12VDC in the big red wire. You have to use a voltmeter to check if there is 12V at the end of the line/wire before it goes inside the amp. In some cases, the fuse might be good but there is corrosion on the fuse terminals and the metal contacts of where it is placed;
2. There is no switching signal to activate/power on the amp. In some setup this is a blue, yellow or orange wire. This can be activated by either the ignition switch of your car, the headunit/stereo, or even a manual on/off switch. This has to receive a 12V also to activate the amp;
3. Internal fault of the amp. The big red wire has 12V, the fuses are good, there is signal 12v to activate amp, but still no power; there is something wrong inside the amplifier. It has to be opened up and diagnosed. This may involve component level repair, circuit analysis, electronics and soldering so you might be better off seeking the services of a qualified professional.
Hope this gives you some ideas and work out for you. Good luck and pls post back how things turn up. Kind regards.

w/out amplifier; dome, and Cig. hint if you cigarette lighter is working and your dome light is working ,the problem is not fuse is the radio.
With amplifier. Amp, Cig, and Dome; again if cigarette lighter and dome light and amp fuse is good then amplifier is bad, or Radio is bad the only hint in this one is that the amplifier control sound if radio has ilumination then the amplifier could be the cause.
All this fuses are located by the lower left side of the steering column.
1. power connection to the battery/amp 2. make sure you have a remote line radio/amp 3. make sure you have rca's radio/amp 4. make sure you have a ground amp/car frame ( scratch paint away for good contact) 5. make sure the speakers are connected to the radio.
if all is ok then check the inline fuse from the hot wire from the battery is not blown and the fuse on the amp is not blown.if so replace them. with the proper amp fuse.
the problem lies in your wiring . you need a amplifier wiring kit u can get best buy that can handle 650 watts and go direct to battery under the hood. just the battery positive running to the + on the amp.make sure the remote wire or the r+ on the amp is not hooked up to power.what radio do u have?
There should be 3 wires on the power side of the amplifier.
Ground - to the car chassis
Power - to the car battery
Remote - to the remote turn on lead from the head unit. (this emits a 12V signal to a relay inside the amplifier for it to turn on when the radio does)

The size of the wire affects the performance of an amp, but the amp should still turn on. 12 volts is 12 volts. So you tested with another amp, on the same wires, and it works fine.The only thing you can really check on the new amp is the fuses in the side. If those are blown, then you should be able to (Unless the amp is fried, and that's why it blew the fuses in the first place) fire it right up. If the fuses arent blown, and you have all your power, and ground, and still nothing.. Well then in that case the amp is just bad, and regardless of the wattage, you just don't fix a Pyle amp.
Well you could have a couple of problems... First, if you have a separate, non-fader output on your radio, make sure the volume on that is turned up. Also check the gain on the amplifier to make sure that is at a reasonable level, usually 3/4 of the way up. Check to make sure you have good connections and wires going from the amp to the speakers. Also make sure that the RCA cables you are using are good, I have ran RCA cables, to find out later that they got pinched in the reassembly of my car . A way to test this is get a set of RCA cables and run them directly from the back of the Radio to the amp without hiding them. I hope I can help. -Andrew Hawkins
Check the amplifiers fuses. Some amps have speaker fuses that leave the LED on if blown. Check for continuity on the voice coils of both subs. Check for 12 volts on the remote turn on line from your receiver. If all of the above are good, the amp is probably toast.
