How do you determine amp size?
Generally you should pick an amplifier that can deliver power equal to twice the speaker’s program/continuous power rating. This means that a speaker with a “nominal impedance” of 8 ohms and a program rating of 350 watts will require an amplifier that can produce 700 watts into an 8 ohm load.
How can I find out how many amps are in a light fixture?
You can also determine both volts and amps by looking on the labels or in the operating manuals. You can look up common figures for standard appliances (most small appliances and lighting fixtures in homes require circuits that range from 15-20 amps and larger ones are 20 to 60.
Where is the distribution amplifier on an antenna?
Unlike a preamplifier you attach to an antenna outside, a distribution amplifier is usually located indoors (e.g., directly after the coaxial cable enters the house and before or after the splitter) Normally you’d use either one of these, although there are situations where you might consider using both, which I describe further below.
Why is there a fourth field in battery calculator?
The fourth field is to adjust for the age of the battery being considered. Since the greatest usage of the calculator is to figure out what battery to buy, usually the box will be left unchecked, as in our example, but it is there in case the batteries available are older.
Where is the best place to install an amplifier?
Good locations to install an amplifier include: Pros: You can use short wires and patch cords. You won’t have to remove a seat or climb into the trunk. Cons: Only very small amps fit here. This puts your amp close to some common noise sources. Pros: Plenty of room for large amps. Near the rear speakers.
Where is the turn on wire on a car amplifier?
The turn-on wire (also called the remote wire) is located behind the stereo. On aftermarket stereos, it’s usually a blue and white wire. The remote wire will “tell” your amplifier to turn on whenever the stereo is powered up (usually, whenever the vehicle is turned on). You’ll have to remove the stereo to get to this wire.
Where does an amplifier get its signal from?
Amp wiring kits often don’t include signal wiring. Your amplifier gets its input signals from the receiver’s output typically via RCA cables. RCA cables come in stereo pairs, in various lengths.
How do you hook up an amplifier to a radio?
There are two ways to do this: get a line output converter (LOC) that’ll adjust the speaker-level signal for your amp’s input, or get an amplifier with speaker-level inputs. You cut the factory speaker wires behind the radio, and connect the wires coming from the radio to your LOC or amp’s inputs.
