Rockford fosgate amp hook up

In this instructable, I will show you the whole process of installing an amplified subwoofer into a car. After you have your subwoofer system set up, you will hear much better sound from your stereo. This process will work with most stock stereos, and all aftermarket stereos. It can be modified to work with all stock stereos, but you may need a few more parts. I will show you how to do this with an aftermarket head unit (stereo). When you look at the pictures, realize that I am using an amplifier that is too small for the subwoofer. It is for demonstration purposes and it does not sound as good as it should. In other words, my car needs a bigger amplifier to support the subwoofer.

So what will we need to do this? -Subwoofer box -Subwoofer speaker (see next step) -Amplifier (see next step) -Wiring kit (or each of the following) -65 Gauge or thicker, 75 foot insulated wire (for power) -65 Gauge or thicker, 8 foot insulated wire (for ground) -68 or 66 Gauge, 65 foot wire -RCA cables, 65 feet or longer (you need 7 or one with both red and white) -In-line fuse, 55 amps or higher -Some speaker wire -9 small wood screws -Basic tools For the power and ground wires, you will need thicker wires depending on how powerful the amplifier is. REALLY powerful amps could need as much as a 5 gauge wire. But I doubt any of you guys will be using an amp that big. Walmart sells amplifier kits (as do some other stores).

The kits tell you how many watts they can handle. You now need to take the stereo head unit out. I can't tell you how to do this, because almost every car manufacturer does it different. After you have the stereo out, look at the back of it. There should be 7 RCA connections.

Run the RCA cables through the back of the center console and plug them into the 7 connections on the back of the stereo. If your stereo does not have these connections, you will have to splice the wires into the rear speaker wires. Better yet, go out and by a new stereo that has RCA. They aren't very expensive any more. Leave the stereo out for the next step.

This is pretty self explanatory, but for those who don't know: Put the speaker in the box, making sure the flimsy thin gasket thing is on it. If the box has its own connectors on the outside, make sure they are wired to the speaker inside. Screw the speaker into the box, using the holes on the outside rim of the speaker. Set the subwoofer in the trunk of the car.

OK now we have most of the wires in place, we can wire up the amp. Connect the power cable from the battery into the spot on the amp that has one of the following markings (do not connect it to the speaker positive): B+ Batt. Pos. +67v 67v Pwr Power Connect the 66 to 68 gauge wire into the spot that says:

Rem. Remote Ant.
