So here it is everyone!
The definitive list of some of the best subwoofers around right now. As you may or may not know, subwoofers are in charge of playing the low frequencies of the sound spectrum. Therefore no matter what size subwoofer you have, it will fill that lower end that the midrange speakers can simply not produce. Due to their design and use, subwoofers are Omni-directional. This means that no matter which way they face you will still feel the force of the subwoofer, unlike midrange speakers for example, where you would not be able to gain benefit of all the detail and clarity they are able to produce if you are standing behind the actual speaker.
Through my experience with different subwoofers, I've found that subwoofers generally become more like tactile transducers as they get louder in essence, you end up feeling the bass more than being able to hear it. As a result, if you're someone that is going for sound quality over loudness, I would recommend using a smaller size subwoofer. Many audiophiles who concentrate on sound quality over sound pressure will choose a smaller size subwoofer as the cone area is much smaller, and as a result, a tighter bass is achieved and when married with a sealed enclosure, the end result will be a nice tight bass that will be precise and accurate while not attempting to crack your windows! However, those who prefer sound pressure will choose the biggest cone area they can fit in their car. Take for example Steve Meade; with regards to his subwoofer he was able to put 4 18 inch subwoofers. The result of these monster subs is that Steve is able to achieve a high SPL. It is apparent that Steve attempts to increase his sound quality by installing large midbass speakers as well as using high quality midrange and good quality tweeters, all manufactured by Rockford Fosgate.
For my system I was restricted for space, and that is what defined to an extent my choice of subwoofer. I needed to have amplifiers that would be as powerful as could be whilst being as small as possible while still trying to maintain a budget! As a result, I settled for the Alpine MRP-M500 and as you can probably tell from the name, the amp is capable of pushing out 500RMS at 2OHM. Sure you might be thinking there’s plenty of choice with regards to a subwoofer but after running a 400 RMS Pioneer subwoofer in my previous system, I quickly learnt that each sub sounds very different and although the Pioneer produce very good subwoofers, (my old Pioneer, now retired to my bedroom!) I found that they were not able to produce the sound I was after which is when I turned my eye to Kicker.
The Kicker L7, a subwoofer that has truly lived up to the reputation and hypes that goes along with it. Yes the first time someone told me they had an L7 as part of their setup I stared at them, blank faced and somewhat lost, but then they gave me a demo and WOW! Although it was not perfect for what I wanted it sounded great! Precise and Accurate as well and the best bit of it all, I found that if I gave it 500rms, although not reaching its potential, it would be more than happy.
For subwoofers, the enclosure is vital for the sub to perform to its best abilities. Although you’ll see many subwoofer packages come with generic subwoofer boxes. While this is not an issue, it does somewhat hinder the performance of your sub. This is why I would recommend a custom made box. By their nature, custom boxes are much larger in size giving the subwoofer the air they require and many people choose to have a ported box, usually tuned to between 30 and 34 hertz. The benefit of this range of frequencies is that you’re pretty much maximising the output of the subwoofer without it becoming solely a transducer. For me, my box was tuned to 32Hz and the result was a sound that is pleasurable to hear as well as giving you the physical experience of moving air and I love it!
So in conclusion, subwoofers are just as important as any other speaker you have in your car if you want to enjoy the full spectrum of your sound, and after having a subwoofer in my car I can guarantee you all that I will, no matter what size, always have a subwoofer in my future cars!

Wires!
Wires and Wiring Kits
WIRES... everywhere! The boot of your car is full of them! They’re coming out from under your carpet, visible by your footwell, tangled, messy, abstract, annoying bundles of utter confusion!!! Sound familiar...? Here is how to keep them simple! Read on...
K.I.S.S
For a car audio system, the wires are one of the most crucial parts of the system (apart from the components themselves!) This is why it is important to use decent cabling in your system, but at the same time, to keep the layout as simple as possible to minimise any potential interference and should anything go wrong, it will be easier to diagnose the problem. There are many different wiring kits available on the market; the difference in price is respectful to the gauges and the quality of the cables.
If you plan to run two amplifiers or more, it is advisable to use a distribution block. This will make the wires look neat and tidy whilst giving you the option should you wish, to have some of your wires on display. Distribution blocks come in many different variations by many different manufactures and whilst some people are happy to chain the power wire from amp to amp, I personally think that the use of a distribution block is quite a nice touch and will make your installation a lot simpler and more pleasing to look at. For my car, the distribution block I chose was able to be used as for both the power and ground, and due to the location of my amplifiers, this was the most ideal solution.
What type of cabling do I need?
The power and ground wires come in different thicknesses or 'gauges' (the term coming from the American Wiring Gauge or AWG for short) The lower the gauge, the more current can flow through, so for example 0AWG wire would allow the most current through. The thicker the wire the more current that is able to flow through. For a car audio system that has several amplifiers or a very high power amplifier, you need as much current as can be delivered. This is coupled in with the fact that as electricity flows through a wire, the voltage will drop, this poses a problem, one which can be remedied by, for example carrying out 'the big three' upgrade, upgrading the alternator or using a higher gauge wire.
The overall idea to use a thicker wire is to effectively reduce the resistance that the electrical current has to go against. From a number of sources, I have also found that it is recommended that wire no thinner than 12 gauge is used, due to a number of reasons, the obvious being the higher resistance as amplifiers have a rated power input, usually, but not always around 14.4v, if the voltage were to drop too much then potential damage could occur to the components as well as the rated power output of the amp being higher than the actual output. Trying to power a high current amplifier using thin wire would be like trying to suck water out of a lake using a chain of McDonald’s straws. It would be like trying to empty a huge swimming pool with a pipe the thickness of a straw, replacing the pipe with a much thicker one will allow for more efficiency and thus a greater flow.
If you buy a wiring kit, inside you will have everything you need to be able to wire up your amplifier into your car. You will have a piece of grounding wire, a positive wire as well as a fuse holder and the RCA cables required by the amplifier to deliver the signal from the head unit to the amplifier. You will also find a thin piece of wire (usually, but not always blue). This wire is what is used as the remote to turn the amplifier on and off in conjunction with the state of the head unit. It may be possible however that the head unit does not have the facility to accommodate a 12v switched signal. If this is the case it is up to you where to find another source of 12v switched power as having the amplifier on even when the engine is off will reduce the voltage of the battery and potentially, if enough current has been drawn, render the battery indefinitely useless. www.the12volt.com have a guide to the ideal gauge wire used depending on what size of length wire is required, however if you, like me have a specific wire gauge in mind, that is higher than what is recommended, from my research I would strongly recommend that it is better to go for the thicker option.
For my car, I opted to use a 4 gauge wiring kit. I felt that this would be the best option as the wire wouldn’t be too thick that it would be resulting in bulges from the carpet while also being too thin that I would encounter a serious voltage drop as my plan was to be running 2 amplifiers and I can confirm that the voltage is kept at about 13.8 volts. Should I wish to undertake ‘The Big Three’ upgrade, the voltage will be increased.
Fuses
As Steve Meade would say
This is true. A fuse is effectively the lowest common denominator in the circuit, therefore should the rated power exceed what the fuse is able to handle it will blow. Fuses should not blow on a regular basis, if they do, it indicates there may be a serious underlying problem and to just keep replacing fuses when the blow does not solve the problem. there are different types of fuses, the blade fuses, AGU fuses, while the more expensive ones are ANL fuses. the difference being the range of amps each type of fuse is able to handle.
Types of Kit
There are many different types of Kits to choose from, however there is a lot of talk of Stinger Wiring Accessories being one of the top brands. I came across one on a forum, a rave review about a Stinger kit that he purchased.
The Earth Wire
Earthing the amplifier is the most important part of powering the amplifier and your car audio system. It is important to keep the ground wire as short and thick as reasonably possible. As the wire is not directly connected to the battery’s negative terminal it is important not to forget that the signal will have to travel throughout the entire car till it can reach the battery negative. For this reason, being able to use the shortest ground lead possible will help reduce the chance of obtaining feedback, without the use of a ground loop isolator. The isolator is seen by some as a quick fix for the grounding problem, however if the amplifiers are grounded properly, then strictly speaking there should be no need for ground loop isolators. However it is important to not forget that although there are measures to reduce grounding issues each car varies in design and some cars even with the utmost care taken, may still encounter grounding issues.
Conclusion
At the end of the day, no matter how much you are willing to spend on the other components such as amplifiers, subwoofers, speakers or head units, the best way to ensure that you get the most out of whatever you have installed, and are able to use them to their full potential, is if you spend the right amount on high quality wires. It could be like the difference between slapping an orange hard enough for a bit of juice to spray out, or squeezing the life out of that orange and drinking every last drop of sweet OJ...
