If you feel like out-thumping your neighbour's car, albeit with a crystal-clear thunder of sound, you may want to buy yourself the Pioneer Premier PRS-A900 Amplifier to sit in your car's boot. This amplifier is a product coming from the Japanese electronics giant, Pioneer and claims to redefine audio quality by reproducing sound in a clearer form. The system is mainly targetted at the discerning audiophile who worships clarity over ear shattering bass. For this, the amplifier features a filter-less design. This essentially means that the amplifier will only amplify sound instead of creating any additional noise or crossfade like other conventional amplifiers.

So, distortion gets booted out of the door and you get clear sound even at high volume levels. Pioneer claims that even the bottom cover of this amplifier is designed to make sure that it doesn't affect the sound adversely. If you ever buy this expensive amplifier, priced at $1500, make sure that you install it properly in your car, replete with it's own sound enclosure. This is very important because every car's interior is differently shaped and thus a proper enclosure and proper positioning only will help the amplifier achieve it's goal of maximum sound clarity.
