The BRP9004 will maximize the low-frequency power and punch of any bass system, whether you've got a simple powered tube or a full-blown competition setup. Simply install this processor between your car's receiver and your outboard amplifiers, and hear what you've been missing. Sophisticated processing restores low bass fundamental tones, and increases your bass response without putting any additonal stress on your speakers. A subsonic filter removes extreme low bass from your signal so your amps and subs will play louder and cleaner.
