How to connect wires to amp

Most amps have 3 places where you need to hook up wires to power them. the 1st is a ground wire that at best is 1 foot long and it goes on the ground or negative 12 volt connection then a bolt on the car you may need to sand off the paint for it to work, 2 a RMT or remote wire that is normally in the middle of the power and the ground connections the remote turns the amp on and off so it needs to go to the remote wire on the radio or a ignition spot on the fuse box - turns on with key on and off when you turn the key off , 3 the power wire is hopefully large 4 gauge wire and goes to the + 12 volt plug on the amp this wire has a in line fuse and goes to the battery and to the amp only. RCA wires go from the radio to the amp and are round and just plug in with no screws some factory radios need a conversion kit you can get at walmart for RCA wires. the speaker wires have some sort of mark or line to tell you what to put were like if you put the line on a negative on the amp you need to put the line on the negative on the speaker box to or it will not bass and could hurt your amp. ask me if you need anything else :) and please rate :/

I have an AudioBahn A4004T Amp. It was working fine and then I had it sitting in my house for a few months. My cousin wants to use it in his car so he hooked the power cables up to his battery to see if it...

If you only hooked up the power and ground the amp will not turn on. You must also hook up the remote wire. This either can come from your radio, your fuses, or your power wire itself. If you hook it up to your radio then it will turn on when the radio is turned on. If your radio doesn't have a remote wire to amp then you can read your owners manual and hook it up to the radio fuse and when the radio turns on the amp will turn on. An lastly you can run a wore from your power wire to your remote plug in. But if you do this the nano will constantly be on if it is hooked up to the battery.

You must have gotten the power lines mixed up. You need to connect the power to the amp and radio the the switched side of the power supply. Or, you connected the amp power and the amp switch wire, usually the blue wire in reverse.

When running multiple amps you need a relay most of the time for the remote wire off the radio this is because the radio was built to power one not multiples. one 12 volt relay may help .check local car audio store. also when hooking up relay it has to have a 12 volt power wire connected to it usually the center pin on the relay is your connection for the power wire the you connect your remote wire from the radio to the relay then connect each amp independently to the relay. Hope this helps write back if not . and if so leave feedback

Were do i plug in the RCA cables from the amp to a factory radio? do i need any sort of adapters if my stereo dose not have inn or outputs? and where do i hook up the remote from the amp?

Most factory radios do not have RCA outs, but most will have a remote wire. Usually used for a power antenna option. Your remote wire from the amp could be hooked to the power antenna wire on the factory radio and it would work great for turning on the amp. As for the RCA inputs on your amp, you will not be able to use them without RCA outs on your factory deck. Although most amps offer a high level input alternative and will use the standard speaker level out on your factory deck. This means the rear channel speaker wires from your factory deck will be used to feed the signal to the amp. You will have to check the instructions and manufactorer recomendations for the amp you are trying to hook up. Have fun and good luck!

How do i install mrp m1000 to two type r 12s step by step.

Hello chadbcavanau,

See the link here for a step-by-step install with photos and amp wiring diagram.

First you need to purchase an amp wiring kit (minimum 4 gauge power and ground). If your vehicle is equipped with the stock radio, you'll also need to purchase a line output converter (LOC).

Hope this helps.

If you used a wire harness to connect with the factory setup, try running the power wire to your fusebox. Find a fuse that is only live when the car is running and insert the wire with the fuse.

Make sure the amplifier is turning on. Remember ther is three wires that power the amp Battery constant, Ground which in a fiberglass boat run ground to battery not motor, Plus make sure the remote wire is hooked to power, generally it is switched power. But if the amp is not turning on temporarily hook remote and power together to battery and see if the amplifier turs on. Second be sure you have a good set of RCA cables hooking the radio to the amp. And finally check and make sure the gain is turned up on the amplifier.
