You will need a battery charger capable of providing up to75 amps at 12 volts DC.
This is called a converter, not an inverter. An inverter takes 12 v and transforms it usually to 120v AC or 220v Ac.
Keep in mind that your 1000 watt amp will not draw 100 amps only briefly at times if at all unless you are at maximum volume. You probably could get by with a 50 amp charger and a big capacitor to supply the boost for a few seconds.
how much energy it draws from your outlet or car battery.
A 5000-watt inverter on a 24 volt system draws approximately 208 amps (5000 watts / 24 volts = 208.33 amps). This calculation assumes 100% efficiency, so actual power draw may be slightly higher.
The inverter draws little current on its own. It is the load that is connected to the inverter. If there were no load on the inverter you could use an ampmeter to determine the no load current. One thing to consider is that a higher wattage inverter would have larger gauge wire which is of lower resistance. This could make the no load current lower for the higher wattage inverter. Bottom line is you would have to measure or have a specification on the no load current.
an analog amplifier is a device used in car audio applications to produce louder and clearer sound. Amplifiers, aka amps, are most often found in the trunk of the car and require semi professional installation. It draws power from the battery of the car amp uses the signal input from the car's stereo as its two inputs. Its output is in the form of current aimed toward a receiving speaker. Again this is generally found in the trunk of a car to power a subwoofer.
For powering a load over 150 watts, you can connect the inverter directly into your car battery. This involves using a 4-guage power cable that draws directly from the positive battery terminal. Without an in-line fuse or circuit breaker, you could short circuit the process.
From what I've read online, the XBOX 360 draws anywhere between 160 and 195 watts. So I would say to be safe, get atleast a 200 watt inverter, and if its going to be in a confined environment, possibly get a larger one so it doenst have to work quite as hard, and wont get as hot.
At 100 volts, around 170 watts. At 240 volts, around half as much. So, I'd suggest a nice 200 watt inverter for the 120 volt model, but that seems to be an awful lot for your purposes. Are you sure that you're not reading the power output of the power adapter, as compared to the amperage it draws on A.C.? I seem to remember using my laptop in a truck with just a 40 watt inverter and it worked just fine.
My side-by-side fridge, which is about 8 years old, uses 70 watts on average. When the compressor is actually on, it draws about 200 watts after an initial spike of ~400 watts. The fridge draws 5 watts when idle.
Turn your radio off before you shut your car off.
Unfortunately, you have not specified a model. The only 5000 BTU model I see on Danby's page is the DAC050MUB1GDB.This device is a 115V machine that draws up to 4.8A of current, which totals at 552VA.Even with really poor efficiency, your 2000W inverter should theoretically run this unit. HOWEVER - most motor-driven devices do not work well on poor inverters and may not start up at all! Also, the inverter and/or the device may heat up excessively.It would be best if you could test the device for an hour before making the purchase.You have not provided the model of your inverter, so I cannot help out any further.
If a piece of furniture? A few draws are usually known as a 'chest of draws.'
Most often something has been added to the car that draws power all the time. Car alarm or car stereo amplifier are two examples. Be sure that everything is off and look for power lights on new equipment. If that's still not working then it will take some work with an amp meter and some time pulling fuses.
