I have a typical Sony Amplifier that is about 4 years old. The power button which has not changed makes a click when I push it. But the unit does not come on in terms of script or power to speakers or anything. I know the plug works as I tested it. What do you think the issue is?

Re: sony amplifier power
This is usually caused by a blown fuse or a blown capacitor. The fuse would be cheap and easy to fix, the capacitor would be expensive and replacement would be my choice. If you are pretty handy with electronics, unplug it, take the cover off the unit, and look near the capacitor for the fuse. Check the fuse for a break in the wire inside it. You can get these fuses at Radio Shack. Hopefully this is what it is, and will be a cheap and easy fix for you.
Let me know how it goes.

The "PROTECT" and "PUSH POWER" messages will flash alternately when the protective device of the amplifier has been activated because a strong signal was input, or if there is a short-circuit detected. Press the POWER button on the unit to turn off the system, and check the following items after "STANDBY" disappears.
1) Are the + and - speaker cords short-circuited?
2) Are you using only the specified speakers?.
3) Is anything blocking the ventilation holes of the system?

Most receivers will click a few seconds after being powered on. This is the relay that turns on the actual amplifier part of the receiver. This is usually the most typical issue in regards to this. Replacement parts may be available but it could require a fair amount of soldering knowledge. Would have it looked at, at a repair shop to verify.
Since the unit is less than one year old, Sony should repair it under warranty. Also, check the extended warranty parperwork. Normally the seller does not provide the actual warranty, they contract with a service company. That company should still be around. If you are not successful with Sony, please post the exact problem and model number and we'll try to get you up and running.
Get an amplifier that is rated just under the power ratings of the subs, that way you will not blow the subs by pumping in too much power to them. An example is, if you have 2 subs that are 500 watts each and you are going to connect them in stereo mode, you need an amp that is no more than about 400 to 450 watts per channel. This will push them very hard, but will not blow them by overdriving them. If you are going to connect 2 subs at 500 watts each in a bridged mode (in parallel across both channels) then you need an amplifier that is about 800 to 900 watts total power for both channels. This is basically the same power ratings for an amp, but some amps are mono (just one channel) and will have just a total power rating, while other amps are 2 or 4 channel amplifiers and have a rating for each channel.
I hope this helps in your decision making, if you need more help let me know. I have been repairing car audio equipment for almost 20 years and have seen just about everything.
