AMPLIFIER INSTALLATION WIRING KITS (HOW TO WIRE YOUR AMP):
1. Get Your Amplifier, Subs, Stereo, and amplifier wiring kit ready. You can find amplifier wiring kits form most online stores. All what you need is a 4 gauge wiring and In-line fuse, you won't need anything larger than 4 gauge.
If you're using an after market head unit, go to an electronics store's stereo department and ask for a wiring harness from your car to the after market head unit example : If you have a Chevy and a Sony stereo go to them and tell them you need a Chevy to Sony wiring harness, they will ask you the year and then go pick it off the shelf, these are usually by the install department behind the counter. once you have it go unscrew your stock stereo, unplug it, plug in your new wiring harness, and plug in the other end to your Stereo, when you buy the new wiring harness make sure its the same shape/size as your stereo.
There are 5 types of amp wiring kits:
- 2 Gauge amp wiring kits: Mainly used for high powered systems and you need to buy a capacitor as well.
- 4 Gauge amp wiring kits: Generally for systems 400 to 1000 watts.
- 8 Gauge amp wiring kits: Is used for systems 100-200 watts.
2. Run your amp wires (battery, ground). Figure out where you're going to place the amp, put the beginning of your power (red) wire there and give it about a foot of wire extra, then begin to hide and run the power wire to under the hood. If you need to drill a hole in the fire wall, be careful not to hit anything on the other side. Make sure this wire is safe from any moving objects.
3. Disattach the power cable from the battery and attach your sub's power wire to the power cable for your vehicle; leave it unattached. If you bought a kit it comes with an inline fuse, if you didn't you need to get an inline fuse. Just cut the power wire, insert the inline fuse and reattach..
4. Place the amp where you want it, then attach the ground (black or brown) wire to the amp. Ground it to a piece of bare metal (not painted); most people unscrew a bolt from a seat attach the wire and screw it on.
5. Now for the RCA jacks, if you're going to use your stock stereo and run the amp from there you want to buy a LOC (Line Out Converter) ~$20. with the LOC you get a small box with 2 RCA's coming out and 4 speaker wires out the other, you want to take out a door speaker and run 2 of the 4 speaker wires to it, pay attention to the pos. and neg. You don't need the other 2 speaker wires, from here secure the loc out of sight and run the RCA's to the amp, plug them into the "IN" RCA jacks. If your using a after market stereo on the back there is 2 RCA jacks, just run the RCA from there to the "IN" on your amp.
6. Now for the Remote (blue wire). If you're using After market Stereo there will be a blue wire coming from the wire harness in the back, mostly these are attached so you have to splice, just snip them and tape off the old end and run your remote wire to your amp. If you're using your stock head unit you have to purchase a toggle switch that fits your fancy, find a cool place to mount or hide it, from here you want to attach the remote wire to your amp, run it to your toggle, cut it, attach it to one terminal, then attach the end you just cut to another one. Then run the remote wire back to the amp and cut it there leaving a foot or so of extra cable. This will come into play later.
7. Get your capacitor as close to the amp as possible, and use the same ground as you did for the amp. Have your power wire taunt and find out where your cap. is going to be, cut the wire, and attach the battery cable to the battery. You cannot just plug it in; you must charge it first with a resistor, use a 1k ohm resistor because they do not get as hot, it only takes a few seconds to charge, do not do this bare handed. You want to ground your cap. and grab a volt meter and place them on the cap. take the resistor and place it in the power side of the cap. and attach the power wire to the other end of the resistor, your volt meter should jump up to around 12.0 Volts, then your cap. is charged.
8. Run the power wire to your amp. If you have a stock stereo and you have the remote wire there you want to in twine the remote wire with the power wire before inserting in the power slot for amp. The remote wire tells the amp to turn on. so if you dont have the remote wire from the after market head unit to turn on the amp when ever you turn on the stereo you have to turn your amp on manually. Make sure you always turn off your amp when you leave your car, it will overheat and drain your battery.
9. Run your sub wires to the amp and screw them in.
10. Turn the gain all the way down, start playing music and turn it up to where you usually listen, where the mids sound good. Tune the gain until the subs sound good.
