Car Audio speakers have become much more than factory upgrades. High-end aftermarket speakers are now designed and built by the same engineers and using the same materials as the legendary home theater and studio monitors. A speaker upgrade can uncover previously unheard instruments and details in your favorite songs that lower quality speakers are unable to reproduce.
Add a little, or add a lot! To some, the subwoofer's purpose is to reproduce a lifelike musical experience by recreating the kick-drums of a live performance. Throw a few hundreds watts into a sub and your driver's seat will become front row to favorite band's best recording. To others, the subwoofer is a thousand watt punisher, capable of sound pressure levels that no human should be subject to. Find the sub that suits your taste and treat yourself (and maybe your neighbors) to a VIP concert.
Tweak, tune, emphasize and equalize your music, just the way you like it! A sound processor will allow you to refine your system's acoustic characteristics to match what was recorded in the studio, or give you the raw experience of a live performance. In this category you'll find products to boost your bass, interface with your factory stereo, or even run an "active" system with individual control for each speaker and tweeter.
Many of your favorite 12 volt brands are available for marine or outdoor use. Often, these products are regular car models with weather resitant coatings, but some are completely designed to withstand moisture, rain or your garden hose.
