Make sure rca cables are tight at the amp and head unit, if you didn't put the sub in the box yourself or buy a retailer.. check the connections yourself. if it's an old amp it may be burnt up. some head units these days require you to turn the sub on (especialy alpine) really need more info on what you got and how old it is.

    I repair car amps for a living. Been doing it for 17 year and have an electronicics engeer degree. Sounds like the outputs are shorted. If it comes on the it's not a power supply problem but if it goes into protech mode it could be a few things. Leyt me know if you want my help. I get amps shipped to me from this site all the time. I am the cheapest amp repair in the USA. I don't charge a bench charge and most prices are $60-$80 plus shipping. Sometime lower depending on the problem. I offer a 90 warranty also.

I have a Marantz Digital Integrated Amplifier PM75 and experiencing with LP's and CD's that I get a loud popping sound , thereafter no sound until after several minutes when it comes back on.

If the sound is common to both channels plus on different functions, it is either a part that is common to both channels or is in the power supply. It will be either in the main pre-amp or power amp, or power supply. If you can turn the bad sound down, it's before the volume control and it's unlikely to be in the power amp section. If you can't turn the bad sound down, it will be in the power amp section.
Remember stereo amps are two mono amps joined together. So the two channels have separate parts for each channel. However some use IC's that have both channels running in them, they can be suspects in this case.

My Technics SUV 660 is making a crackling and popping sound regardless of where the volume is. It does reduce once the amp has been on for an hr or so. Also the speakers are not consistantly on. Any a

If the sound is on both channels then it's probably a device that is connected to both channels. I don't think it's the power supply. I rather suspect it's in the power amp section, since it's not affected by turning up the volume. If the amp uses one of those STK devices as a power amp, it could even be that.

Marshall MB4410, with low volume gives no real volume,

Guitar amps have preamp sections (think unpowered audio mixer) and power amp sections (Crown rack-mount amp). An excellent way to isolate audio problems if amp is still producing audio is to check the preamp out (line out). Preamp output distorted = preamp failure. Connect MP3 player to "Power Amp In"...sound distorted = power amp failure. In your case the latter is the case as your "line out" is clean. Also test each speaker for clear sound as speaker cone damage from being overpowered is fairly common. At 300w. I'll assume the failure was not from cranking the volume to loud but a shorted speaker or speaker wiring could zap the power amp in an instant.

My turntable connect to Carver Preamp, I bought a

If you can hear music with the volume up, but like it was turned down low (from the power amp), then yes there is something up with it. If it's the same on both left & right channels, then it's something common to both. For instance the power supply, or an IC that has both channels going in it.
If however the power amp does produce sound normally with another device, then either the turntable has a fault, or the pre-amp has, perhaps on the pre-amp inside it for the cartridge.

Bxi 1606d amp it turns on power up but no sound

Well i sounds like your amp is shot. Or you have the subs wired incorrectly to the amp. Each amp is different in stability with ohm loads and each amp performs differently at each load. Sounds like it was wired at the wrong ohm load in the past or it came defective from factory. Definately send it back if u just got it.

My amp overheated on a Klipsch promedia 2.1

Sounds like your speakers had too many watts sucking from an amp that couldn't produce the power to feed them.
What is the max watt power output rating for your amp?
Compare the amperage of all the speakers combined and make sure they are 15% lower that the rating on your amp. Be sure to include the sub in your totals.
Chances are you've blown the power supply on your amp.
Have you tried any of these checks yet?
