FAQs

Can you run 2 amps off one power cable? ›

The best way to wire multiple amps to a single power cable is to use a power distribution block. That allows you to use a single cable for most of the run, including the crucial portion that passes through the firewall, and then use shorter individual cables to connect to each amplifier.

The first step is to determine which ends of your speaker wire are positive and negative. For speaker wire with connectors, the positive is often red and the negative is black. Once that's done, connect one positive end to the positive terminal on your speaker and the other positive end to your amp or receiver.

1. What hits punchier, the 4 Ohm or 2 Ohm? Ans: If you are looking for hard-hitting bass effects, both 4 Ohm and 2 Ohm subwoofers are good. The first one offers a louder sound, while the latter One is known for the more profound bass effect.

Subwoofer manufacturers make subs with dual voice coils (DVC) to take advantage of this difference in wiring schemes, so the user has more freedom of system design. A DVC 4-ohm sub can be wired into a system as a 2-ohm or as an 8-ohm load.

Therefore, connecting a single 4-ohm speaker to a 2-ohm rated amplifier would be perfectly safe, as the speaker's impedance is higher than the minimum rating of the amplifier.

Typical sizes of wires for 100 Amp Service are 4 AWG or 2 AWG for copper wiring and 2 AWG, 1 AWG, or 1/0 AWG for aluminum or copper-clad wiring. These sizes are also used for direct burial. When choosing 100 amp service wire size, remember that a 100 amp circuit at 240V can proceed up to 24,000W of electricity.

Wire Size for 100-Amp Service

Most 100-amp service panels require #2 AWG wire. Electricians use these wires when there's significant space between the circuit breaker panel and electrical equipment (such as air conditioners), which is common in large commercial buildings.

A 3-channel amp can take care of a single pair of speakers plus a sub quite effectively. Most people choose to use a 4-channel amp to run a pair of speakers and a sub — two channels to drive the speakers and the other two bridged together to run the sub.

What is a black wire with a white stripe for? ›

In an AC system in the United States, black will indicate an ungrounded conductor, also known as the hot wire. This is the line that will bring power from the panel to your load. As for the black wire with a white stripe, it could possibly mean another hot wire. Maybe your load runs on more than one hot wire.

It means that one wire is marked, typically with a stripe, to denote negative or positive. Most applications use the striped side as the negative, like speakers.

As far as your negative wires go, the white wire is a negative wire. You should connect this one to the negative wire in an outlet or ceiling fan after all the positive wires are connected. The green wire should always connect to the grounding screw or wire, which is usually green.

US AC power circuit wiring color codes

The protective ground is green or green with yellow stripe. The neutral is white, the hot (live or active) single phase wires are black , and red in the case of a second active. Three-phase lines are red, black, and blue.

For the most part, the wiring colors on aftermarket stereos and these adapter harnesses are standardized. That wasn't always the case, but these days you can pretty much count on the red wire being switched power and the white wire being the positive lead for the front left speaker.
