Adding an amplifier to your car’s sound system is one of the best ways to make your music clear, clean, and loud. There is a wide range of amplifiers available on the market, and it’s important to match one to your system to make sure you’re getting the best performance. Familiarize yourself with everything that goes into choosing an amp (or ask an expert), and you’ll find the one that’s right for you.
Do You Need an Amplifier for Speakers?
A sound system doesn’t work at all without some kind of amplifier. Most cars have a low power amplifier built into the stereo head unit. The real question is, “do you need a good amplifier for your speakers?” The easy answer is that upgrading the amplifier for your speakers is a lot like brushing your teeth– you don’t technically need to, but you really should to get the best results. Most cars don’t come from the factory with a good dedicated amplifier, and low-impact aftermarket enhancements won’t include an amp either. If you want to get a good audio experience in your car, a better amp is key.
How Many Amps Does a Car Amplifier Draw?
Since an amplifier draws power from your vehicle, your alternator amp rating can help determine how much power you can install. The reserve current capacity is generally about 40% of your total amp rating. From there, you can calculate the current draw of a particular amplifier by converting the wattage (accounting for inefficiency) into amps by dividing it by the voltage of your alternator (12 volts).
If you don’t want to dive into that kind of math, just divide the total fuse rating by two. That is, add up the value of all fuses in the amp, then cut it in half. This will give you a rough ballpark estimate. To eliminate the need for both math and guesswork, the easiest way to get a precise answer is to consult your local audio experts. They’ll be able to tell you how much power a given amp will draw and if your car can support it.
What Does an Amp Do in a Car?
An amp takes an audio signal and amplifies it, sending increase power wattage to your speakers. The signal on its own isn’t enough to power the speakers (or any other component like a subwoofer), and the amp is what creates the wattage strength you need. A better amplifier provides a better signal for those speakers, and you’ll get better bass with a dedicated amp (or a dedicated channel) to drive your subwoofer. An amp upgrade will produce noticeably better sound from your entire sound system, and you’ll especially notice it in three critical areas:
- Make Your Speakers Sound Better – No matter how good your speakers are, they won’t be able to do much with a bad signal. The better your speakers are, the bigger the difference will be when you add an amp. If you’ve upgraded to aftermarket speakers or sprung for a fancy speaker system from your car’s manufacturer, you should definitely make sure the amp is pulling its weight.
- Better Sound at High Volumes – If you like to crank the system up when your favorite sound comes on, you might notice that the quality plummets as the volume rises. That’s a sure sign that your amplifier is underpowered and should be upgraded. A quality amp will also eliminate signals thru the crossover filter that are beyond your speakers capability, keeping the speaker from damage by not overdriving them.
- Bring the Bass – If you have a dedicated subwoofer, you almost definitely need to add an amplifier. Your built-in radio simply doesn’t have the right channels, wattage, or frequencies to power that kind of bass.
