About the Soundstream Reserve DPA1.2000D
A sub amp with the features you want
A sub amp with the features you want
Soundstream designed their Reserve Series DPA1.2000D mono amplifier to supply your subwoofer with plenty of power, and give you the ability to fine-tune the amplified sound to match your sub with digital precision. The DPA1.2000D can send your sub up to 400 watts RMS of bass power.
Digital signal processing
Digital Pre-Amp Tuning features include variable low-pass, and subsonic filters, along with a variable bass boost and phase control. All settings are made by button and confirmed on the digital display. The low-pass filter has an unusually steep slope (48 dB/octave) to accommodate the widest variety of subs you might use in your system. A wired remote lets you control the bass level from your front seat.
Soundstream Reserve
Soundstream knows that Crutchfield offers free lifetime tech support for the gear we sell — and that's one of the reasons why we can offer you their Reserve line of compact and powerful car amplifiers.
