If you are looking to add enormous low-end sound to liven up your car’s playlist, then picking the best car subwoofer for your car is just 50% of the equation – the second half is finding the right power amp to control the subwoofer. Since low frequencies have such long wavelengths, car subwoofers need to move a lot of air. If you attempt to wire your sub to the auto stereo, as you do with the car speakers, it won’t have enough energy to move the speakers. Without a power amp, your auto subwoofer is only a bowl with an extensive magnet.

However, there are a wide range of power amps, and every amp is intended to control diverse sorts of speakers and subwoofers. You can’t just pull a power amp off a shelf and expect it will work with your subwoofer. Some important aspects regarding the power amp needs to be fixed before you can add the power subwoofer in the car audio system

Few Aspects To Consider While Installing a Power Subwoofer

Channels

The best power amplifier for a car subwoofer is a single channel amp. This implies that the amp forms a single sound sign through one channel, which is wired to your subwoofer. You can wire different subwoofers to this single channel, yet every sub gets the same mono recurrence. Low-end frequencies aren’t for the most part heard stereophonically like the midrange and high-run frequencies your car speakers produce, so one channel is everything you need. The best power amps additionally have channels and tone controls that permit you to enhance the bass proliferation.

RMS Watts

Subwoofers have two power handling specifications – RMS watts, also referred to as continuous power handling, and peak watts, or peak power handling. The RMS (root mean square) wattage of the subwoofer shows the measure of force the subwoofer can deal with on a consistent basis. The peak wattage shows the most extreme measure of force the subwoofer can deal with for brief periods before encountering harm.

You have to coordinate the RMS watts of the subwoofer with the RMS watts of the force amp. Numerous force amps list a RMS watts range. This reach shows the base and most extreme force that the amplifier is equipped for producing. If the power amp has a wattage range, you need to guarantee the base force is 75 percent of your subwoofer’s RMS watts and the greatest is 150 percent of the RMS watts.

In case you’re ever in uncertainty, remember that an overwhelmed subwoofer is superior to an underpowered one.

For each extra subwoofer you introduce to your framework, the power amp’s wattage range needs to mirror the extra sub’s RMS watts. For instance, if you introduce two subwoofers with a 300 RMS watts rating, then you require a force amp with a force scope of 450 to 900 watts. Moreover, both subwoofers need a large portion of the power to remain efficiently active.If you choose to include a second or third subwoofer to your auto sound collection, you have to redesign your power amp as well.

Subwoofer : Impedance

Impedance measures electrical resistance. Coordinating the impedance with your power amp is similar to coordinating a water funnel to a faucet – the water won’t stream effectively if you attempt to fit a little pipe on a huge faucet, and the other way around. Impedance works similarly. If you neglect to coordinate the impedance accurately, your power amp and your subwoofer could over heat, leading to damage and terrible audio.

Most auto subwoofers give you the choice to buy a model with an impedance of either 2 ohms or 4 ohms. Coordinating impedance appears like a decently solid idea at first glance, and more often than not it is straightforward in case you’re simply introducing maybe a couple of subwoofers. However, it can get entangled when you’re managing numerous subs or double voice coil subwoofers, which have two input and output connections. For instance, in case you’re introducing two 4-ohm subwoofers, you require a power amp with 8-ohm impedance. In case you’re introducing a double voice curl subwoofer with 2 ohms, you require a power amp with a 4-ohm impedance since every connection has 2 ohms.

Once you’ve found a power amp that matches the RMS watts and impedance of your subwoofer, you should simply interface the subwoofer to the amp and connect the power amp to your auto stereo. A legitimately fueled subwoofer can be the difference between listening to a lifeless playlist on your drive and rocking out wherever you go.
