Unless your vehicle has a built in amplifier or your installing an aftermarket one then you can leave it off. A remote wire will turn on an audio accessory if you have one.
the remote wire goes into the back of the deck (head unit). it tells the amp to turn on when the deck is powered up, if you don't connect it it will continue to drain power from your battery.
Either your remote wire from you head unit to your amp is broken or not connected properly, you don't have a remote wire, or your head unit is faulty. Try another piece of cable as your remote wire from your head unit, and if it still does not work, your head unit is faulty. To save buying a new HU, you could wire the remote wire to your accessories, but be cautious as you could flatten your battery quickly if wiring incorrectly.
Connect the positive (usually red), earth (usually black) and accessories (usually blue)into the new head unit making sure the positive is fused. Connect the speakers into the head unit and away you go.

well, you set up your power, remote, and ground wire. Then you need to run your RCA cables to the back of your head unit. After that, you just connect your speakers to the amp and your done.-Shocker
There will be a wire on the back of your head unit that turns the amp on. It will be marked something like "rem" "remote" or "amp." If not, consult your head unit manual.
These jacks are used to connect the head unit to a separate, more powerful amplifier. If you are powering your speakers directly with your head unit then these jacks are not headed. They can also connect to a subwoofer amp if a crossover is used to block the higher frequencies.
Yes you can. You need to buy an inline convertor that takes the speaker output from the back of the head unit and turns them into RCA outputs. Then you need to find any wire that powers up when the car is on and off when the car is off. Splice into that wire from the Remote turn on wire. The rest is a simple.
Your head unit should have a wire marked as P. Antenna that's the wire you need to connect.
If the spark plug is not sparking when removed from cylinder head its probably the Remote cut off, try unplugging the unit and connect then 2 leads together. There are 4 leads two into a single plug for power. the other to are on separate plugs connect them together.....check for spark.
With some stereos there is a remote faceplate capability. The stereo?æ will have to have the remote plug and cable extensions to mount the faceplate.
You have to change the head unit to the ones which has an aux input or iPod connector because the OEM head unit only has a single CD/cassette player & radio.
