About the Soundstream Reserve RSM4.1200D
Soundstream packed an unbelievable amount of power in this tiny, hand-sized RSM4.1200D amplifier that'll fit in almost anywhere in your car — putting out 75 watts RMS to each of your front and rear speakers. You can also bridge the rear channels to blast a subwoofer with 220 watts RMS while powering the fronts with 75 watts each. And this amplifier generates all this power from a chassis with a footprint of 7" by 3-3/4", with a Class-D design that keeps heat and current draw to a minimum.
Soundstream pays attention: they know 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 super-compact and very powerful car amplifiers.

Channel Configuration: The SoundStream RSM4.1200D is a 4-channel amp; essentially two full range 2-channel amps built into one chassis. Both amplifier sections are bridgeable, so it can be configured as a 4-channel, 3-channel, or 2-channel amplifier.
- Power Output:
- 4Ω: 75 watts RMS x 4-channels
- 2Ω: 110 watts RMS x 4-channels
- Bridged: 220 watts RMS x 2-channels into 4Ω
- Gain: The input levels are independently adjustable for the front and rear channels. The input range is 0.25 volts to 6.0 volts.
- Crossover: The amp has independent
crossover controls for the front and rear channels. The
crossover slopes are 12 dB/octave:
- Mode: three position switch; choose high pass, full range (crossover is bypassed), or low pass
- Frequency: set the crossover point; rotary dial; 35-250 Hz
- Power Input: Two set-screw terminals are provided for connecting the power and ground cables. The terminals accept up to 8-gauge wire. (10-Gauge minimum is recommended.) The set screws are tightened/loosened with a Phillips head screw driver (not included).
- Remote: The remote turn-on terminal is a set-screw and will accept up to 10-gauge wire. (18-Gauge minimum is recommended.) The set screw is tightened/loosened with a Phillips head screw driver (not included).
- Speaker Outputs: The four pair of speaker output set-screw terminals will accept up to 12-gauge wire. The set screws are tightened/loosened with a Phillips head screw driver (not included).
- Line Level Input: Two pair of stereo RCA jacks feed the front and rear channels.
- Speaker Level Input: Two 8" 2-channel wiring harnesses are included for speaker level input.
- Fuse: There is one 30-amp ATM fuse, mounted inside the amplifier case.
