If you are talking about an amplifier to be installed in a vehicle with a 12 volt system then you would use the formula to find the amps. I = W/E. 1800/12 = 150 amps. A 1/0 copper wire is rated at 150 amps.
See relate links below.
Yes, there are ground wire gauges. The approiate size ground wire must be matched to the size service you are installing. For instance a 200 amp serivce must be grounded with a # 4 bare copper ground wire.
14 gauge will handle it with a 15 amp breaker. If you use 12 gauge use a 20 amp breaker.
The smallest size breaker is a 15 amp and with a #14 wire which has a capacity for 15 amps and a 120 volt source, this combination will give you the capacity up to 1800 watts. W = A x V, 120 x 15 = 1800.
There is no one wire that is rated for 1800 amps. The service will have to be a quad parallel of the conductors. A 600 MCM conductor with an insulation factor of 90 degrees C is rated at 475 amps. This conductor paralleled into four equal lengths will give an ampacity of 1900 amps for each leg of the service.
Depends on the size of the sub-panel in that garage. If you are installing a 60 amp sub-panel 400 feet away from the main service panel then use AWG # 4.
The recommended subfloor screw size for installing hardwood flooring is 2 inches in length.

For installing baseboard trim, it is recommended to use 18-gauge brad nails that are 2 inches in length.
Depends on the size of the amplifier you are installing and the power required to run it. You can easily install a 500 watt amp with no problems.
