Far as I know it's just size of wire, smaller the gauge the thicker the wire. which means the 4 is going to be thicker than the 8.
The recommended gauge for copper wire to handle a 100 amp load is typically 3 AWG (American Wire Gauge).
on a 4000 watt amp the best gauge wire woul be between 2 and 0
A 30 amp electric range typically requires a dedicated 240-volt circuit with a 30 amp breaker and 10-gauge wiring.
You'll need RCA style cables to connect from your headunit to the amp. You'll then need Speaker Wire to run from the outputs of the Amp to the speaker terminals. You'll also need a heavy gauge power wire. A wiring kit such as the StreetWires Power Station PSK04Ri 4-gauge amplifier wiring kit.
An amp is the actual amp while an amp chord connects the instrument to the amp.
i would say a 4 gauge kit would be more then enough for it 8 gauge min...
1 amp
For a 20 amp circuit, it is recommended to use 12-gauge Romex wiring. Romex is a brand of non-metallic sheathed cable commonly used for residential electrical wiring.
For a 30 amp breaker, the appropriate wiring setup is to use a wire gauge of 10 AWG for copper or 8 AWG for aluminum. This ensures that the wiring can safely handle the electrical load without overheating. It's important to follow the National Electrical Code and any local regulations when installing the wiring for a 30 amp breaker.
The ampacity or amp rating of all wire is rated by the size of the wire. NM (non-metallic sheathing) wire is no different. In household wiring 14 gauge wire must go on a 15 amp breaker/ 12 gauge goes on a 20 A and 10 gauge goes on a 30 Amp.
Not much. Keyboard amp will have a better frequency range.
at least 4ga wire but it would be best to get 4awg or 0awg. 4 gauge is smaller than 4 American gauge wire
