An amplifier is designed to boost audio signals sent from the source, such as your phone or laptop. It amplifies electric currents to increase volume and improve clarity. A powered subwoofer on the other hand uses its own internal amplification, so it can be connected directly to the source without needing an extra amp. Subwoofers use special drivers that create deep frequencies which are not produced by ordinary speakers.

Both components bring their own unique capabilities to any stereo system, allowing you to enjoy a more immersive sonic experience than ever before. Whether you're looking for crystal clear highs or earth-shattering lows – there's something out there for everyone!

Will I Need To Add A Crossover Or Equalizer To My System?

It is estimated that 400 million cars are equipped with amplifiers worldwide. With so many drivers relying on these devices, it is important to understand how they work and what accessories you may need for your own system.
