![]() It gets tricky when you need to factor in the impedance and the wiring. Your amp should be able to supply the total RMS rating for this subwoofer system.Īdditionally, figure out the total impedance load that your subs could be wired together to form. This will be the total RMS rating of all the subs. Now, get the Watts RMS rating of each sub, then multiply this by the number of subs you want to install. Remember that if you have or plan to have multiple subs and one amp in the room, the subs all need to have the same impedance (Ohms) or coil type otherwise, the power won’t be distributed evenly.

To get the best results out of your amp/sub pairing, pick an amp that is capable of delivering anywhere from 75 to 150 percent of a sub’s watts RMS. In an amplifier, the RMS is the amount of power it can deliver. This measures how much power your sub can handle without getting damage or without distortions in sound. A subwoofer’s power output is expressed as watts RMS (root-mean-square). As such, the number of Ohms of the subwoofer needs to match with the power output of the amp. The number of impedance is expressed in Ohms. The amp, in turn, puts out the amount of power based on this load. Impedance refers to the amount of load your sub transfers to an amp. Through this, you will find out how big your amp needs to be in relation to your subwoofer. But this task is tricky because matching involves knowing the specifications of your subwoofer and understanding how an amp fits into these specs, or vice versa. It is crucial to correctly match your amp to your sub. So, using an external amp with your active sub just to push the output to extreme levels is not ideal. Otherwise, too much power could cause damage to both your external amp and active subwoofer. You have to ensure that the specs of your devices are in line. Testing out this kind of connection comes with a cautionary warning, though. In this setup, the amp serves as the channel through which data passes between passive speakers and the rest of the sound system. But people who connect the two do it mainly for data transmission purposes because other workarounds aren’t possible. You can connect an external amplifier to an active subwoofer if you think it would improve the sound. ![]() Can You Use an External Amp With an Active Sub? And because it operates as a single and self-contained unit, it is the ideal pick for smaller spaces. ![]() If you have a passive sub, you will need to get an amp that generates enough power to sufficiently sustain the deep tones produced by your audio player.Īn active sub, meanwhile, is easier to set up because it is already an all-in-one solution for homeowners who need optimal bass. It is also the wiser choice if you are setting up a custom home theater system or a recording studio. It is ideal for larger spaces that need multiple units or if you need a more spread-out bass. All it needs to work is an audio source.Ī passive subwoofer, on the other hand, relies on an external amp or receiver as an additional power source. It is designed with the ability to sustain all the power it needs by keeping its speaker/amp configuration well-aligned. Active SubwooferĪ premium powered or active subwoofer draws power from a built-in amplifier, so you would no longer need an external amp for it. There are two types of subs: passive and active sub. This is why it is important that you first know the type of sub you plan on buying or the one you already have. However, not all subwoofers need a separate amplifier. Does a Sub Even Need an Amp in the First Place?Īll subwoofers need an additional power source since reproducing low-frequency sound signals requires large amounts of power. ![]()
