Amp Amplifier
When you are on the look out for car audio amplifiers, first you got to know how it functions and what is it used for. The purpose of a car audio amplifier is to convert a low level signal from the source unit to a high level signal for driving the loudspeakers. Amplifiers can range in power from 20 watts to over a thousand watts per channel. And their prices too differ from one amplifier to another depending on their features, quality and power. The most popular type of amplifier is the one with 2 to 4 channels model.
If needed, you can even add extra built-in features to car audio amplifiers whenever required. Some of these extra built-in features may include, crossovers, speaker level units, equalizers, and signal processing. While purchasing an amplifier for your car stereo system, there is one thing you need to take into consideration when it comes to dealing with amplifier power ratings. You should see that all power ratings are not created equal. The true measurement for an amplifier power is the RMS rating or the continuous power ratings.
Quality of the car audio amplifier is very important to take into account when buying the amplifier. But the question is how do you know if it is a high quality amplifier? The good indicator of a quality amplifier will be determined by the weight and the size of the amplifier. The heavier the amplifier the better the quality it will produce. But size is not all that matters
Another indication that you can consider is the quality of the car audio amplifier by the size of the fuse used. There are different classes of amplifier, and a quick and easy way to check the true power output is to take the fuse value of the amplifier or the sum of the multiple fuses and multiply it by 6, if it is an A or B class amps, or 10 for class D amps where the efficiency is higher. Though this will not give you an accurate result, but it will be able to indicate if your car audio amplifier is close to the specifications.
If you have a tight budget or lack of space, the most economical thing to do is to opt for a multi-channel amplifier with the required built-in processor and features that you need. This will save you a lot of money and space, which will in turn allow you to add any extra feature to your car audio amplifier. Though there will be difference in quality compared to the outboard processors but this will not be noticeable. Sometime adding too many components can lessen the chance of noise entering into the system.
To sum out in brief, the key features you need to look into before purchasing a car audio amplifier includes, bridgeable, channels, connectors, class, crossovers, distortion, filters, power output, efficiency, speaker level input, stability, separate gain controls, tube amplifier, tri-mode out put, power supply, pre-amp inputs and outputs. But make sure that you always opt for genuine brands through genuine dealers.

The market for independent sound cards has seen a decline over the years. This can be blamed on chipset manufacturers equipping motherboards with HD sound cards that provide acceptable performance.
The Vista driver debacle that plagued Creative's X-Fi range did little to strengthen the public's opinion of costly sound cards. In the old days it was deemed a worthwhile upgrade to a system, because it offered a game port and took some load off the CPU. These days the CPU can easily handle the sound requirements for a game and with USB there is no need for game ports any more. So why does a system need a dedicated sound card? Truthfully it doesn't. You however do.
The Asus Xonar Essence STX is not aimed at gamers but rather at an all-round audio experience. In other words it should perform equally well with games, movies and music. The first thing that will surprise most people is the lack of 3.5mm jacks (these are the small headphone jacks). Instead, Asus have opted to use the larger 6.3mm jacks as well as 2 RCA outputs (left and right). The card comes bundled with a 6.3mm-to-3.5mm adaptor and a RCA-to-3.5mm Y cable so you can use your headphones on either. These ports make complete sense for audiophiles, especially those who work with sound equipment, like DJs. Fewer converters means less loss of sound quality. The line-in/mic-in is also a 6.3mm jack, so recording from sound equipment will be a breeze.
Two features about the Essence STX most impressed. Firstly, the built-in headphone amp gives more than enough volume to any pair of cans that you have. Secondly, and by far the most exciting of all the features of the card, you can upgrade the opamp. An opamp (operational amplifier) handles different and varying inputs into a single output. Different opamps can have varying effects on sound quality. Some provide a richer bass experience while others enhance the high end of the EQ. This is a curious thing for Asus to do, but a welcome one none the less.
The asking price is a bit steep for an object of desire rather than need, but the quality makes it worth the price. Music simply explodes with life. A good set of headphones makes music sound spectacular but a sound card of this quality upgrades it to the classification of phenomenal. Music has more depth than ever before - and this is across the board, from old classics like Eric Clapton with his guitar to Kings of Leon - Sex on Fire. Watching Saving Private Ryan on Blu-Ray almost became a religious experience with the landing at Omaha beach gaining a new level of realism.
This we can confidently attribute to the Essence STX. While the Essence STX is not aimed at gaming it doesn't disappoint when put through its paces. The sounds of bullets ricocheting off walls and rockets whizzing by is enough to make even the bravest of men cower under their desk.
It might be pricey but if you want your music, movies and games to reach a whole new level of awesomeness, your standard onboard is not going to deliver. The Asus Xonar Essence STX makes a significant difference to the overall experience of using your computer.
