Types Of Subwoofers
How to Install Subwoofers Author Info. The most cost effective first step is to buy an amplifier wiring kit off of an internet auction site, etc. This will come with a huge power wire, a short ground wire, a remote wire, and many times an inline fuse and various connectors to help keep the install organized and looking clean.
Some stereo shops have huge spools of wire available by the foot. This is another cost effective alternative to buying a wiring kit, if you know the dimensions of your car. Run the 12v power wire usually the longest wire in the kit, mostly red, typically ranges from 8 gauge to 0 gauge from the battery through the firewall and then to the amp. You can find a hole somewhere in the bottom right of the firewall.
Don't connect the power wire to the battery or the amp just yet.
Find a solid metal ground somewhere near the amplifier. You'll need to stay within 2—3 feet 0. A way you can do this is pull up the carpet and scrape the metal until it is bare metal with no paint left on it. If the amplifier is to be mounted in the trunk, many times bolts from the suspension can be found directly above one of the rear wheels. These suspension components usually bolt directly to the frame, making them an ideal grounding point.
Pull the aftermarket CD player out of the dash. There is a blue wire with a white stripe hanging out of the back of the deck known as the remote wire.
The remote wire is a simple 12v signal that the cd player outputs to tell the amplifier to turn on. It's a small box that has 4 input wires and the 2 necessary RCA output that will run to the amplifier. It takes the high level speaker voltage and drops it to a low level signal the amplifier can process.
Run all the wires straight back to the amplifier. RCA cables should be run down the center of the car as RCA cables can pick up sounds from wire looms and also air con vents power wires. Use Speaker Wire to connect sub-woofers to amplifier. Gauge isn't extremely important here, as long as the wire is copper, the resistance-per-foot is in the mili-ohm range, meaning there will be minuscule, if any, voltage drop across the wire.
There are many different types of enclosures sealed, vented, bandpass, infinite baffle, etc. There are numerous articles explaining the pros and cons of each type of enclosure, far too many to list in this article. If you really want the best response possible, your subwoofer manual will list the ideal enclosure volume for each type of enclosure.
How To Connect A Subwoofer To A Car Stereo Without An Amp
If you don't want to go through all of the volume calculations, just buy a box slightly bigger, and stuff it with pillow stuffing from walmart until the subs respond the way you want them to. Be sure to know the impedance of the subwoofer s you are using and try to match the amplifier's impedance accordingly. For example, if you have an amp that is w 4 ohms, and w 2 ohms, you'll want to try to run your speakers at 2 ohms.
Two 4 ohm subs can be wired in parallel to achieve this. If you're new to the impedance calculations, many amplifiers will have specific wiring diagrams in their manuals to assist. Put a fuse into 12v wire in the engine bay no more than 0. If your amp kit came with an "inline fuse holder", you'll want to find a nice location to mount it in your engine bay. Once it's secure, cut a length of the power wire to reach the fuse, and connect it to one side of the fuse holder.
The other side the side you just cut is stripped and connected to the other side of the fuse holder. Connect the power wire to your battery.

Then under the hood clamp the wire down to the battery. A word of warning, sometimes you'll see a nice big spark the first time you touch the power wire to the battery. Don't worry about it! This is the amplifier charging the huge capacitors contained inside. Do not turn up the volume or gain too high or you may produce clipping in the subwoofers.
This is where the output of the amplifier peaks and stays there for a split-second. This is bad for the subwoofer because it holds the cone the big circle part! Not only are you not producing a single decibel of sound during this microsecond, but you're also working the voice coil very hard and damaging it. You can get them in various abilities and sizes.
For your car, I will advise these type of subwoofers especially if you have a compact car. They are manufactured to cater for a particular kind of car, and thus each design is meant for a specific car. It is worth noting that, the real audio power for your car stereo comes from the low end, the bass. When you feel the music touching your heart when played, it is the bass doing the magic. The following features should be considered when purchasing a car subwoofer:. There are several ways which you can use to connect a subwoofer minus an amp.
Remember, subwoofer comes with two codes, one for audio output and one for power. But the thing is, some subwoofers are more complex, depending on the model that you have chosen.
You can use the following:. The LFE port is a special one for subwoofers only. You will be able to locate it as it is normally only one RCA connector on both ends. Alternatively, it could be having clips made of springs which will be at the other end of most available speakers. If your cable has an end that is split and has both the R and L, then you will need to plug both of them in. If the car stereo has both the R and L RCA plugs for the subwoofer output, you should also make sure that both of them are plugged in.
If your subwoofer uses spring clips to connect the speaker wire, you will need to use the output of the car stereo to hook it up. When doing all this, make sure that you mind the channels. If there are two sets of spring clips On the box of the subwoofer, for In and Out, you will need to connect one of the speakers to the subwoofer, which in turn connects to the car stereo to pass the audio signals.
But if there is only one set of spring clips On the box of the subwoofer, you will then have to share the same receiver connection as the speaker. Get the best subwoofer for your car stereo that will be easy to connect minus an amp.
