Installing a PC Subwoofer is as easy as choosing your favorite color. Subwoofers are a complete set of loudspeakers and are dedicated to low-pitched audio frequencies. If you have a desktop computer and a music lover, it is best that you have a subwoofer.
Go to a computer shop or electronic store to choose the best brands of subwoofers because the best brands are long lasting. Some of the subwoofers may cost between $200 and $300 minimum. Sometimes the best brands are expensive but if you want a cheaper one, you can just set it up yourself. In fact, there are also online auctions with self-help kit.
Subwoofers are very popular equipment because it gives deep, strong bass to your sound system. The subwoofers divert the notes that full-range speakers cannot reproduce. Subwoofers come in different sizes and shapes and some of its kind are unpowered, component subwoofer, plate subwoofer and a lot more.
How do you install a subwoofer?
1. Unpack the subwoofer and speakers.
2. Position the subwoofers on your desired place and note that you have to identify the left and right speakers. Be careful with where you are going to install the subwoofers, its best that you position the subwoofer at a safe place as well.
3. Shut down the computer and connect the cables of the speakers and the subwoofer. There is also a manual that will guide you with regards to where the cables should be attached. There are cables which are hired-wired to each other but there are cables that are not. Connect the jack of the speakers to the computer. Usually the jacks are color coded so all you have to do is to match the colors of the jack to the colors of the port at the back of the computer. The kit should also have an illustration of the wiring with its corresponding numbers. With this illustration, the installation will be easy to follow.
4. Plug the speakers to the power supply and turn on the speakers.
5. Start the computer.
6. Test the speakers by playing any music from your desktop computer.
Note that the subwoofer does not have a built-in amplifier so you need to hook it up with an external amplifier as a source of power. Also, although some subwoofers come separately, it is advisable that it is installed in an enclosed space to operate properly.
There are amplifiers used to power up your subwoofer. There are amplifiers that are solely designed for subwoofers and there are some that use a normal pro audio amplifier. The most commonly used amplifier is the plate amplifier which usually includes a crossover. The plate amplifier often times has the crossover mounted in the speaker enclosure.
A crossover separates the frequencies which the subwoofer does not receive. There are commercially available crossover materials which are mounted externally or simply buy a plate subwoofer. Most subwoofers are crossed over at 100 HZ and lower. The crossover points depend on the main speakers and as well as the room where the speakers are setup.

How to Do a Custom Pioneer Car Audio Install
Pioneer car audio install can be done by you. You do not need a professional to come and take your money while it is so easy to plan how to achieve a successful Pioneer car audio install. I have used the word plan because installing any car audio requires exactly that. You need to spare some time and employing lots of concentration will go a long way to help you achieve your goal. Firstly, you need to consider what Pioneer car audio you are installing. They may be stereos, speakers, amplifiers, subwoofers, or even subwoofer boxes. Some of the most tricky to install are speakers and amplifiers. Your chosen Pioneer car audio systems should reflect what you want to gain from the systems. They need to be of the right fit and of very high quality.
Firstly, you need to consider where to get the information that you need. The guides may be in form of manuals or they may be print outs from sites or downloads. Whichever your source is, make sure they have the right information to guide you. Apart from being concise and legible, they should be accurate. If you need to have images to direct you, there are DVDs available to help you go step by step as you install your Pioneer car audio. Make sure you read on the various tips that are available for each car audio product you plan to install. Going through the manual in a car audio store will ensure that those hard or complicated steps are solved by the store staff. You therefore need to visit stores with staff who know about in depth details of a particular product.
Once you have all the information that you need, it is time to go to work. Get the tools that you may need. These tools may be crimping tools. These tools are used with a hammer to crimp terminal into wires. You also need connectors like butt slice connectors. You also need terminals like spade and ring. If there is any soldering to be done, which there usually is, be prepared with the appropriate tools. Take your time to make sure that every detail is in the correct order. For people who wish to rush through things blindly, this is not for them. You need to forget about other things and concentrate especially when you are doing the wiring as you undertake Pioneer car audio install.
When you have done your installation and everything does not work out as you hoped it would, it is not a time to give up. Slowly go through the procedures again and you will find the reason why you went wrong. If this does not work also, look for a professional who is trained to do this and hand over the job to them. The bottom line is to get the car audio safely installed in your car by whichever means possible. There are so many Pioneer car audio install manuals from their site and you can register to receive even more information through your email. When you are content with your results, congratulate yourself for doing a good job. You will feel so good when you know that you have a car audio system installed in your car, that will not disappoint.

Whats the easiest way to install a 2channel Amplifier and Subwoofers?
Ecah subs watts RMS should match each channels watts RMS on the amp.
You will need to...
Run a power wire of the correct guage from the battery with a fuse no more than 18" from the battery to the amp. The fuse should be a total of the fuse rating on the amp.
If you don't have an aftermarket stereo, run a wire from the ignition ACC to another switch to the REM (remote) connection on the amp. This allows for full control and you never have to worry about forgetting to turn off the amp. The switch is so you can turn off the amp at will so as not to give grandma a heart attack in the car.
If you do have an aftermarket stereo, connect the blue remote turn -on form the HU to the REM connection on the amp.
The ground should be the same size as the power wire and securely grounded to the chassis of the car.
You can use a "line level converter" tapped from the speaker out of the head unit if you don't have an after market HU. If you do, run RCA from the output to the back to the amp.
Something to consider...this is an example...
To calculate the current draw of an amplifier, multiply the number of channels by the RMS watts per channel (a 2 channel amp rated at 2000 watts RMS per channel would be 4000 watts). Double it to account for amplifier inefficiency (4000 watts X 2 = 8000 watts), then divide by the average output voltage of an alternator, 13.8 volts (8000 divided by 13.8 = 579 amps). Since the average music signal requires about 1/3rd of the average power in a test tone, divide by 3 (579 amps divided by 3 = 193 amps).
This is an average approximation of current draw and can go higher. So I would gather between 194 and 289 amperes for this system.
The alternator of a:
compact car is about 35 amps
mid-sized car is about 65-75 amps
SUV is about 145 amps
Calculate 40% of the amperes of the alternator you have now. This is the average current the car uses when running. Add this number to the approximate average current draw of the amps, and you will come up with the actual size of alternator you need.
If the number you come up with is the same as what your alternator supplies, you need to take no action.
