How to Choose the Best 5 Channel Amp
So, you know of a number of top performing 5-channel amps.
But you still have to close in on one amplifier that best matches your listening needs. Maybe you want to get rid of the boring distortion you experience from your car stereo or the system’s inability to crank up your favorite jams.
We’ll discuss the most important factors to consider as you aim to give your audio system the best upgrade.
1. Does the amp meet your system’s power requirements?
You need an amp that will make your system sound better. Volume and bass are definitely top on the list of required improvements. But your speakers and subs have specific power ratings (RMS and MAX power indications). These ratings should guide you when choosing the best amp for the system.
One important thing to remember is that you’d rather overpower than underpower your speakers and subs. Underpowering speakers often damages them. As such, consider amplifiers that have an RMS rating higher than that of your speakers and subs.
2. Is the amplifier bridgeable or not?
While it’s obvious that 5-channel amps are designed mainly for 5-channel systems, it doesn’t necessarily mean that the same amp cannot be used with a 3-way system. The only requirement is that it is bridgeable. Most of the amps reviewed above are bridgeable and we did that intentionally.
If you’d like to change the composition of your car audio system in future – for instance to add more speakers – you’d better buy a bridgeable amp today because it offers more flexibility.
3. What is your main reason for buying a car amplifier?
There are many sound ills that 5 channel amplifiers treat. What is the most disturbing problem affecting your car’s sound system?
4. Check the impedance rating
Every amplifier has an ohms rating, which describes its impedance - how hard it has to work to drive power through. The lower the impedance, the easier it is for the amp; and the higher it is, the harder the amp has to work. Most 5 channel amplifiers have a rating of 4 or 2 ohms, but always check to ensure you get the right one for your audio system.
5. Other desirable features
The following qualities make an amplifier more desirable to real users. Check them out.
- Thermal, voltage, and short protection – especially crucial for amps with high power capabilities.
- Adjustable equalizer – gives you more control over your system and ability to tweak your music to your liking.
- Subwoofer remote control – gives you control over your sub from the driver’s seat.
- Amps that are easy to install
- Aluminum covers - excellent heat dissipation
Lastly, don’t forget to consider the size of the amplifier to ensure that it fits in your vehicle. Technology has made it possible to design extremely compact amps. You can get an amp as thin as a textbook and as long as your palm. Make sure you check the installation space requirements before buying your new amp.
Best 5-Channel Amplifiers 2020 FAQs
Q. How is a 5-channel amplifier configured?
A: A 5-channel amp is usually a combination of two amplifiers. A common layout is where a 4-channel amp is combined with a 1-channel unit. This amplifier combo can power four speakers and one sub. The one channel for the sub is more powerful as it has to drive more power compared to what channels for regular speakers need to drive.
Q. Why should I go for a 5-channel amplifier?
A: 5-channel amps are a great addition to your system if you have/or plan to install one speaker for each corner of your car and a powerful sub at the back. The amplifier will power all your speakers better than most amplifier setups as each speaker is served by one dedicated channel. In other words, there is no sharing of channels between speakers.
Q. What are the advantages of a bridgeable amplifier?
A: Bridging multiple amplifiers is a common way of increasing the power supplied to a speaker. It is useful when you want to drive a single voice coil (SVC) or single channel subwoofer. While the process is bridging is easy, it should be left to professionals to avoid problems with sound quality. Some of the issues that result from faulty bridging include harshness in the highs and midrange as well as thin bass. Amplifiers to be bridged must be identical.
Q. How do I tune my 5-channel amplifier for the best sound?
A: Buying an aftermarket amplifier is an excellent step toward better audio. The other critical step is tuning the amp so that it reaches all your speakers and subwoofer, and it attains its full potential. Failure to correctly tune your amp not only results to under performance but also puts the rest of your audio equipment at risk of damage. Here are the settings you need to understand to set up your amp for optimal performance:
- Level/gain: Used to match head unit (Bluetooth player, radio, etc.) output voltage with amplifier output voltage.
- Crossover (X-Over): This setting has predetermined frequency ranges
- HPF and LPF filters: After setting crossovers to an appropriate frequency range, you can use high-pass and low-pass filters to further dial the crossovers. Proper tuning of crossovers and filters eliminates sound distortion and reduces the risk of damage to your amplifier, speakers, and subwoofers.
- Bass boost: Be careful with this setting. Turning up the bass boost adds more kick to your low-frequency notes. However, turning it up all at once is a direct route to distortion and possible damage to your sub.
- Other critical settings include the subsonic filter and remote (external) bass control.
Q. What should I consider first when choosing an amplifier: impedance or power rating?
A: Many people make this mistake: choosing an amp based on its power rating without first considering the impedance their subs can and cannot provide. Finding an amp that can do 2000W RMS does not mean it is the right amp for two subs each with a power handling of 1000W RMS. What impedance (ohms) are the subs wired to provide? Can the amp match this impedance? If yes, you can consider the amp, otherwise it cannot work with your subs. It’s inherent to remember that wiring subs to the wrong impedance is one of the most common causes of burnt voice coils and blown subwoofers.
Q. Can I install a 5-channel amplifier even though I have less than 4 speakers in my car audio system?
A: Yes. If you have, say three speakers and a subwoofer, you can still use a 5-channel amplifier and leave one channel unused. Having more power for your speakers is not a problem. Under-powering them is a problem. Having an amplifier with unused channels also gives you an opportunity to add more speakers to your system in future.
Q. Which are the best places to install a 5-channel amp?
A: When planning on where to install your amp, it helps to consider how you will route connecting wires. Popular installation locations for amps include in the trunk and under a seat. Record the measurements of these spaces and use them to select an amp of the appropriate size.
