About the Soundstream Reserve DPA4.1600D

An amp with the features you want
An amp with the features you want
Soundstream designed their Reserve Series DPA4.1600D 4-channel amplifier to supply your speakers, tweeters, or subs with plenty of power, and give you the ability to fine-tune the amplified sound to match each driver with digital precision. The DPA4.1600D can send each of your front and rear speakers 80 watts RMS, for some pretty robust rockin'. Or, you can power a couple of front speakers with 80 watts each while powering a subwoofer with up to 320 watts RMS from bridged rear channels.
Digital signal processing
Digital Pre-Amp Tuning features include variable high-pass, low-pass, and bandpass filters, along with a variable bass boost. All settings are made by button and confirmed on the digital display. The high- and low-pass filters have unusually wide ranges (20-20K Hz) and steep slopes (48 dB/octave) to accommodate the widest variety of tweeters, speakers, and subs you might use in your system.
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.

Features
Channel Configuration: The SoundStream DPA4.1600D is a 4-channel amp; essentially two full range 2-channel amps built into one chassis. Both sections are bridgeable, so it can be configured as a 4-channel, 3-channel, or 2-channel amplifier.
Specifications:
- Power Output:
- 4Ω: 80 watts RMS x 4
- 2Ω: 160 watts RMS x 4
- Bridged: 320 watts RMS x 2-channels into 4Ω
- Signal to Noise Ratio: 70 dB
- THD: 0.5% (at 4Ω)
Protection Circuitry: The amplifier features built-in circuitry to protect against overload, short circuit, and overheating (160° Fahrenheit or higher).
Display: Along with the top mounted controls, there is a digital display. Normally either the input voltage or amp temperature is displayed. When adjusting any of the top mounted controls, the current setting is displayed.
Controls: The controls for the front and rear amplifier sections are independent and identical. Other than the input gain, all the controls are on the top of the amp. The top mounted controls are labeled 1CH-2CH (front) and 3CH-4CH (rear).
- Gain: two rotary controls to match the amplifier to the output of the source unit; variable from 500mV to 8V
- Level: output level; separate from the input gain control; range 1-20
- High Pass: high pass crossover point; range 20 Hz to 20 kHz with approximately ⅙ octave spacing; can be used as a subsonic filter
- Low Pass: low pass crossover point; range 20 Hz to 20 kHz with approximately ⅙ octave spacing
- Band Pass: both the high pass and low pass crossovers can be used simultaneously to create a band pass frequency range
- Bass Boost: bass boost level centered at 45Hz; range 0-14 dB
Connections:
- Input: two ports for use with the included RCA input harnesses; when using speaker level inputs the RCA plugs can be cut off following the instructions in the manual
- Power/Ground: set screw terminals; will accept up to 8-gauge wire (8-gauge recommended)
- Remote Turn-on: set screw terminal; will accept up to 8-gauge wire (typically a much smaller wire is used)
- Speaker Output: the included harness has wiring for all four speakers
- Fuses: three 20-amp ATM (blade) fuses installed on the end of the amplifier; 60-amp fuse (minimum) also required on the power wire within 18" of the battery
- Thru-Out: proprietary line output jack; requires the cable included with the DPA1.2000D subwoofer amp
