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 :/

Ok, relax. The purpose of the harness is to wire you radio to it, then be able to plug into the factory harness without cutting wires. Let's start from scratch. The harness you have should have all the wires you need IF you told the retailer all the specifications of your vehicle. Basically the harness should have a positive, negative, switched power, and speakers (4 sets). Speaker wires are generally grey, green, white, and purple. Constant power is red, switched power is yellow, and ground is black. However, you unit may have other wires coming off of it, such as remote turn on (usually blue), RCA outputs, and will have an antenna jack that you may need an adaptor for. Sometimes factory harnesses have two plugs. Sometimes they are not required for the radio to be functional (it may be the output and return for an external amplifier that you are currently bypassing). So follow the instructions on the package. Don't feel like you have to be stuck in your car to hook your radio to the harness either. Hope this helps.

I just bought a VC KS-AX4302 amplifier. When hooked up to power, the amp immediately turns on and the deck turns on and starts playing music, with no key in the ignition. Both stay on until the power is...

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.

I have two amps one for my speakers and the other for my subs it was working fine but recently one of them turned off. I thought was a short circuit and bought a new one but still doesn't work. Its looped...

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

Need to know the wires to install a deck for 97

Red is power to from ignition to cd deck
Yellow is direct power from battery to cd deck to hold the memory.
Black is ground
Blue is only needed if you are hooking up an amplifier.
I always suggest buying a wire harness quick connect system for $5, then you won't have to cut origional car wiring. If by chance you are taking the original wire route, then go to to find which wires on the car are for what.

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.
