L.A. Car Accessories Philippines has low prices on car subwoofers, boxes and enclosures to put ground-pounding power behind your favorite tunes.

Subwoofers are speaker units dedicated to reproducing lower-frequency sounds, and many audiophiles consider them an indispensable part of astereo system. A subwoofer adds impact to a listening experience by adding power to bass notes, sound effects, and other low-frequency noises. Subwoofers can be either passive or powered. Passive subwoofers are units that include the speaker only; they require an external amplifier to power their big bass sound. Powered (also known as "active" or "amplified") subwoofers are fit into enclosures with built-in amplifiers. Powered subwoofers do not require a separate amplifier.

Deciding between a passive and a powered subwoofer for one’s car is a matter of space, sound, and budget. Powered subwoofers tend to be smaller, and therefore slightly less powerful, than their passive counterparts, so they are often a good choice for people with smaller cars or less powerful car batteries. They are also less expensive to install. When considering purchasing a powered subwoofer, consumers should consult car audio magazines and websites to get a better idea of what is available, and what models within their price range have the best performance. It also helps to have a basic understanding of how subwoofers work, as well as the most important technical specifications for subwoofers. The right powered subwoofer can dramatically improve a listening experience.
