In this instructable, I will show you the whole process of installing an amplified subwoofer into a car. 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 Stuff needed to hook up subs 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.

For the power and ground wires, you will need thicker wires depending on how powerful the amplifier is. Walmart sells amplifier kits as do some other stores. The kits tell you how many watts they can handle.

This can be a tricky step. You want to choose a speaker and amp that put out the most power, without blowing each other. What you want is the RMS of both the subwoofer speaker and the amplifier to be as close as possible. The RMS is the amount of power a speaker can continuously have sent to it without going bad. The RMS is also the amount of power the amplifier can continuously put out without over heating.

When looking at speakers and amplifiers, do not look at the peak power. A speaker or amp can only be run on the peak power for about a minute before it goes bad or overheats. You want to be running your subwoofers on its RMS rating rather than the peak rating. For best sound, keep the impedance Ohms the same too. This amp has the following ratings when it is in "bridged mode".

Smaller speakers like the 8 and 10 inch ones, are very quick to respond and punch better than bigger ones, but are not very loud. The bigger ones also handle lower frequencies better too.

Make sure you buy a subwoofer box that has a hole the same size as your speaker. We will start with wiring the power from the battery. It is important to get the power from the battery and not the fuse box. Power from the fuse box often is "unclean" and you may hear your engine noise amplified through your speakers. You could also easily blow a fuse by using the little ones the fuse box has.

Start by finding an opening in the car's firewall. This is the metal wall under the hood of the car, closest to the windshield. The other Stuff needed to hook up subs of the firewall should be the inside of the car. I chose a hole that was behind my glove box and was fairly easy to get to from the engine compartment. Run the majority of the power cable through the hole in the firewall, making sure to leave enough wire to get Stuff needed to hook up subs the battery. Strip the insulation off of the wire at the end where the battery is. Wire the in-line fuse to this end if it is not part of the wire already.

You want the fuse as close to the battery as possible. Do not connect the wire to the battery yet. Make sure you tape the place where you wired the fuse to the wire, so you don't get a short. Run the remaining wire under the cars carpeting or through a wire channel, if there is one. You want to get this wire to the trunk of the car. While you have the carpeting loose, run the 16 - 18 gauge wire and the RCA cables from the trunk to as close to the back of the stereo head unit as possible, leave a little slack at both ends. You now need to take the stereo head unit out.

It usually requires you either take off the front of the center console, or you use a tool to slide the stereo out of special clips. After you have the stereo out, look at the back of it. There should be 2 RCA connections. Run the RCA cables through the back of the center console and plug them into the 2 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. You will need to run the 16 - 18 gauge wire through the back of the center console too.

This wire tells the amp that the stereo has turned on, and that the amp should too. If you look at all the wires coming out of the back of the head unit, there should be 1 or 2 blue ones. These are called the remote wires. If there are 2 wires, there should be one labeled Amp.

If there is just one blue wire, you can use that. If you have a power antenna, you will have to splice into the blue wire for use with the amp too. What you need to do is connect the 16 - 18 gauge wire to the correct blue wire. When the stereo comes on, so will the amp. If it is a stock stereo on a car without a power antenna and no blue wire, then run the 16 - 18 gauge wire to the fuse box, and connect it to a fuse that turns on when the accessories are on.

Your amp will always be on when your car is on, but it shouldn't make noise, so its OK. If it does make noise like from the engineadd a switch so you can turn it on or off. 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. OK now we have most of the wires in place, we can wire up the amp. Remote Ant. Connect the 3 foot, 10 gauge wire to the one marked do not connect it to the speaker negative : B- Neg v Gnd Ground Connect the other end of the ground wire to a nearby bolt that connects to the body of the car.

There may be 2 channels. If there are 2 channels and you can bridge your amp, do it. I won't explain bridging but its easy and you can Google it. The final step is to go and connect the power cable to the battery. I just shove my wire between the battery clip and the post on the battery. Question 19 days ago. Hey I just switched my old single din for a new 9. And im used to the old rca jacks and I got serval different rca jacks coming from the headunit. Aux in, audio,camin,and subwoofer which one do I used cause I tried and didn't get my subs to play.

My question is is there any rewiring in my vehicle that's necessary or can I just switch them out without error.

Thank you for the instructions and detailed post. Just a few things I'd like to add with respect to the original author: bmlbytes A high amperage fuse between the battery and amplifier is absolutely necessary. I think most of us have experienced the awful electrical smell and the after effect of that condition. Some decks stereos also offer dedicated sub-woofer outputs. The benefits of using those outputs is the ability to adjust the output that is sent to amplifier and then to the sub.

I prefer that method if applicable than Stuff needed to hook up subs the knobs potentiometers on either the amp or powered sub to match the desired speaker volume. I understand the need for the initial calibration settings on the amp, however it is convenient to have control over the sub-woofer independently, especially if you find yourself next to a member of the older population we all get there eventually who tend to not Stuff needed to hook up subs the wonderful sensation of properly tuned bass.

I Stuff needed to hook up subs find, with years of experience, that using crimped and soldered and heat-shrinked round connectors on every screwed connection to be the safest and most secure way to go. If you don't want to use connectors, at least solder the ends of the wires for a solid connection that also prevents fraying. If you don't plan on removing the sub or amp often, why not take the few extra minutes? This might not be too relevant, however I have also seen every single clear plastic amplifier cover melt if mounted in a spot that receives direct sunlight in hot cars.

Question 3 years ago on Step 2. I bought 2 channel outline converter from e bay and I need to tap into factory cable speakers but not sure with speakers I should tap. My front speakers have no Bass at all and rare speakers are batter and with some Bass.

Can any of you help me. I have had my sub for a few years and recently I had a few things in my boot, as i went round a corner something fell and it pulled ripped one of my cables off my speaker picture below. Is this something i can easily fix?
