Best Car Amplifier Buying Guide and FAQ
When you’re dealing with sound equipment, there are near infinite things to get into in terms of dcb, RMS power, and everything in between. Let’s get into every detail you could possibly need to worry about when you’re deciding which car amplifier is right for you, and some frequently asked questions to clear the air.
Factors to Consider When Buying a Car Amplifier
There are a lot of working parts to your new audio system, so let’s break them down piece by piece and showcase what you should be looking for in a car amp.
- Channels – These play into your decision majorly. We’ll get into these more below, but the main difference between channels are power, audio quality, and heat.
- Power – This is where you start getting into the logistics of RMS and peak performance. Power is everything; it’s one of the three main reasons behind any car amp purchase. Not having enough power to back your amp is a huge mistake.
- Size – Are you going for under-the-seat amplifiers, or filling up half of your trunk? Either way is fine, but it will impact cost and performance, so choose wisely.
Q: What Kind of Car Amplifier Should I Get?
Watch it – this step’s a doozy. There are essentially six different types of car amplifiers you can get, so it depends on what works best for you. Each one of these different degrees of amplifiers are basically measurements of power. Let’s break them down by type:
Also known as class D amplifiers, these tend to produce a bit more power than their older brother – the dual channel model. Class D amplifiers utilize multiple transistors, however, they are generally either in an on or off position – there’s not a lot of wiggle room here, so you’ll end up with a load of sound, or nothing at all.
You get a lot of distortion with mono channel speakers, despite the fact that the sound passes through a filter. Overall, they’ll do the trick, they’ll refrain from pushing out a lot of heat, but they’re mostly used solely to power a subwoofer and don’t show a lot of promise on their own.
You can power two speakers to get more of a surround sound output, and can also handle subwoofers with ease. These are optimal for trucks or vehicles with no trunk space; you’d put these beneath your seats. You can use both channels to power one speaker/subwoofer for maximum output.
You get two types of circuitry in one amplifier, making this perfect for trucks or SUVs with no room in the trunk to spare.
This is when you get into the big leagues. You can pack a full speaker system and support it with four channels; these are ideal for those wishing to turn their trunk area into an audio arena.
In the same way that a three channel system works, a five channel is really four channels, plus one that powers the subwoofer. Odd-numbered systems can sometimes be a pain, so be sure that this is something you really want/fits with your vision before you commit to a purchase.
You won’t see a lot of six-channel amplifier systems out there on the market. These are mostly found in large SUVs or Humvees for maximum power, sound, and audio quality.
Is 2 or 4 OHM Better in a Car Amp?
This gets a little into it, so here goes everything – your amplifiers are the power source for your music, which are relied upon by subwoofers and your speaker system. Your amplifier compresses electrical currents in its circuitry, outputting different watt numbers. Those differing watts are used to identify your OHM, and what the result will be.
Let’s say that your amp produces 100 watts of power, and that comes through a 4 OHM speaker. It’s going to produce 200 watts of power for a 2 OHM speaker. Using those basic principles will help you identify exactly what’s going on in your sound system.
Now, which one is better? The higher your OHM, the better – some models may even include up to 8 OHM. This depends on the wiring providers to your subwoofer, transferring everything into a “load,” sort of like the language that your subwoofer will understand.
More OHM = more capabilities, but also, in most cases, requires more wiring. Depending on how hardcore you want to go here, you may want to opt for a 2 OHM to get excellent sound without sounding like a mobile dancefloor.
Max (Peak) vs RMS Power
Let’s identify what each of these actually mean, and get a firm grasp on the key differences between the two.
Max Peak – The grand total of how much wattage your speaker can handle in bursts. Your speaker is going to output various electrical levels at different times, peaking at sharper points in your audio. Your max peak should be ready to handle it.
RMS Power – This is how much continuous, steady power your amp can run at a time. Your RMS power is better equipped to identify and manage your most frequent wattage use.
In a nutshell, they’re both important metrics for measuring the sound that comes out of your new amplifier, and what your system is going to do with that sound. If you run music that’s too high on wattage and your peak performance can’t handle it, you could end up damaging your equipment.
What Role Does a Car Amp Play?
When you hear about hooking up a fantastic sub(woofer) or epic speaker system, they both rely on the amplifier for power and performance. Without an amp, you’re dead in the water.
Where Do I Mount my Car Amp?
Get ready for a flashback to the 90s. For the most part, depending on the size of your amplifier, you’re going to want to stash it and hook it up in the trunk. Some amplifiers will be better off stored beneath seats (usually the passenger seat since the driver’s seat will have more mechanical/automatic parts).
If you’re going to go with the trunk route, here are a few things you should know before installing your new amplifier:
- Get an Amplifier Wiring Kit
You’ll have to pay attention to the gauging, but any wiring kit is going to be of significant importance to you. When you go with a well-rounded kit, you get additional power fuses, lengthy (17 feet on average) wiring, most comprised of the standard copper clad aluminum, and more.
- Don’t Bolt it Down
Sounds crazy, but here’s the low-down: we’re all about enhancing your car, not prohibiting it – bolting your amp to the metal chassis of your car, specifically, the inside of your trunk, is going to cause major issues. Vibrations will rattle the entire body, mimicking engine/fuel injector problems, so you won’t be able to identify other issues with your ride. On top of that, it produces an aggravating atmosphere, which isn’t the reason you’re looking to buy a car amplifier.
- Never Mount Upside-Down
If you’ve heard the buzz that it produces a superior sound, you may be right. However, it also traps and projects heat which can damage your amplifier, as well as overheat your trunk. Too much heat can fry circuits, which isn’t what you’re going for.
