SOURCE: remote wire

there should be a remote wire for your amplifier on the back of your stereo if you have an aftermarket stereo. It's usually a blue wire, if not you can always hook it to the same remote wire as the one your stereo is running off of.

Wiring the System:
Wiring is an important factor in your audio system. You need enough power cable to run from your car battery's positive terminal through the firewall to the amplifier. The thickness or gauge (AWG) of the power wire is very important because you want to make sure wire can handle the power demand of your system. To find out the right gauge you must ascertain the approximate current draw (in amperes) of your amplifier (or amplifiers). First, calculate the total power of each amp (multiply the number of channels by the number of RMS watts per channel). If you have multiple amps, add up the total power figures to arrive at a grand total. Second, double your grand total power figure. Finally, divide by 13.8 — the result is your system's approximate current draw in amperes. Be sure to install an in-line fuse or circuit breaker near the battery. Without one, an accidental short circuit could pose a fire hazard and damage your amp (not to mention your car). Your ground wire should be of the same gauge as your power wire and must make direct contact with the body of the car. Look for an existing bolt or screw that makes contact with the car body closest to the amp. Remove the bolt or screw, and scrape away any paint or grime. A star washer will help your ground wire maintain solid contact with the car body. Use a ring terminal on the end of the ground wire, to keep it securely fastened to the bolt or screw. If you cannot find a convenient ground screw or bolt, drill a hole for one. Be careful not to drill into the gas tank, a gas line, or a brake line. If you are grounding multiple components, try to ground each one separately, with about a half-inch of space between each of the grounding points. If you'd rather use a single bolt, place the ground for the most current-hungry component (probably the biggest amp) closest to the body of the car. Put the ground for the component that draws the least current (probably the electronic crossover) on top. The last wire you need for powering the amp is a turn-on lead. It does not need to be as thick as the power and ground wires (18 gauge should be fine). It runs from the remote turn-on lead at the back of your receiver to the remote terminal on the amp. When connecting these wires, be sure to use crimp-on spade or ring terminals to get the best signal transfer. Your car's alternator ampere rating determines how powerful an amplifier you can install. An alternator that cannot handle your power demand will hurt your systems output. Here is how to find out if your alternator can do the job for your system. Multiply the ampere rating by 40%, and you'll get a rough idea of how much power demand your car's system can handle. An alternator capable of producing 55-65 amperes is usually adequate for systems up to 350 watts RMS. A Japanese car with a 35-amp alternator can accommodate around 125 watts of power, while a German car with a 90-amp alternator can handle a 500-watt system. Heavy-duty capacitors connect to the power cable (just before it reaches your amplifier) and act as a buffer zone between your amp and your car's electrical system. They store up a reservoir of power that can supply the amplifier's peak demands (like a kick drum beat) without having to get current from the battery. Capacitors come in half or full Farad. You can use one or link as many as you want depending on what your system demands. Car audio competitors often replace their vehicle's alternators with heavy-duty upgrades to accommodate big power demands. An amp can be securely installed with just a few screws. But since amps can be sensitive to electrical and motor noise and because interference from the amp may affect your radio reception, try to mount it at least 3 feet away from the receiver. When working inside the trunk, tape over the latch, so you will not become trapped inside accidentally. If the amp is in the trunk, run the input signal leads down the same side of the car as any speaker wires you have installed. Run the power and turn-on leads down the other side of the car to avoid interference. Do not mount an amp or other car stereo components such as electronic crossovers or equalizers directly on steel — you will invite noise problems. Instead, mount the amp on a non-conductive board and mount the board to the car body (or use rubber grommets under the screws to isolate the amp). Before you drill the screw holes to mount your amp, hook it up and give it a test run. If the amp is operating correctly, with no engine noise, then proceed with the installation. There is also a safety issue here: Components that aren't securely mounted could break loose during an accident and injure someone as they fly through the passenger compartment. Use bolts and nuts or screws to secure amplifiers and other components to their mounting locations.

have a good day

I have lost all my wires to my Bunker Hill security camera item 95914 how can I make some more

Hi Jeff
It looks like the camera use an RJ 45 Plug to transfer the signal and power to the AV and power plug connectors. All you have to figure out is which pin goes where.
Power uses 2 pins, Video uses 2 pins and Audio Uses 2 Pins.
So you can get a network cable with an RJ45 connector at the end and connect the AV and power plugs on the other end. I just dont know which pins are witch.

Nissan almera 1997 stereo wiring

to bench test you need a speaker, a 12 volt power supply, and something to add as an antenna wire about 3 ft long..most radios have a power wire, ground, memory, and 4 mated speaker leads..others also have these nw rca connections for hookup to an auxilary amp, determine which is power(usually red orange or yellow with a fuse in the line..a blak or brown ground wire, a yellow or white memory wire.. and the speaker leads should be mated lines 2 front and 2 rear.. now since this is going in a nissan..please do a photo of the wires on the radio and a photo of the wires in the car system and I may help you figure this spaghetti mess not power up anything unless you are absolutely sure whats what or you will burn up the radio..

Im installing a after market radio and cant figure out what wires are the ground, power, ignition power,

Usually the ground is black. Power is red, Memory (constant power) is yellow, antenna/amp trigger is blue. Speakers usually have corresponding colors to each one. As an example if one is purple, then the negative wire that goes with it to the same speaker is grey with a purple tracer... I hope I've helped. If so please rate my assistance. Thank you and Happy Holidays.

I have a 93 honda civic hatchback and the person who owned it before me cut the wires for the stereo and i just bought a pioneer deh2100ib and cant find the ignition wire

you must have a tester light .ground the light then one by one test the wires,the one that has power when the car is in off position is your battery back-up and thats gonna go to the yellow wire on your deck,next find the wire that only has power when the key is turned and thats gonna go to the red wire on your look for a ground wire usually black but not always test to make sure no power is coming out,if u cant find a ground make your own by drilling a hole somewhere in firewall or under carpet sand the area to make a clean ground and use a wire no more than 18 inches you can now turn on the deck. to figure out speaker wires pop the trunk and look at the speakers the wire colors will match up front,then front speakers u may have to remove to check colors

Pioneer DEH-P5800MP CD Player not powering on.

did you try the fuse behind the wireharness. if so check the yellow wire and the red one for power. also check if you have ground on it. if you want to make things simpler try to connect the black wire to the battery neg. and the yellow and red together on the positive of the battery and see if it turns on.

I would like to get my amp out of my car but i cant figure out how to disconnect the ground wiring

The ground wire can be cut and be spliced in at a later time so its safe to cut the ground to the amp and tied off for later use. Otherwise it would be a needle in a haystack of wires to find the ground lead. Thanks Rulds2008

Problem with aftermarket stereo wireing

seriously the answer is very easy the yellow wire from the deck is constant power weather the truck is on or off it should always be hot. The red is the ignition wire which simply turns the deck on when the ignition key is turned on and the black is ground besides the actual speaker wires these are the only wires that need to be connected. if they are properly connect there is a good chance that there is a short somewhere
