About the Soundstream Reserve RSM4.1200D

Tiny giant

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.

Features

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

Controls

  • 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

Connections:

  • Power Input: Two set-screw terminals are provided for connecting the power and ground cables. The terminals accept up to 8-gauge wire. 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. 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.

Customer Q&A

Q
What is the minimum gauge wiring recommended?
[ Michael  Dec 02, 2020 ]

A
I believe for the power and ground it was 10 gauge. I used 8. I would say that the larger size is better, less resistance means cleaner power and these amps need the power to deliver their potential! As far as the rest of the wiring I am sure 12 or 14 is fine, I used 12.
[ Joseph  Dec 02, 2020 ]

8gauge Enter
[ CAMERON  Dec 02, 2020 ]
A
Accordingly to Soundstream- Make sure that the leads to be connected to the +12V and GRD terminals of the unit respectively must be larger than 10-Gauge (AWG).
[ ANGELINO G  Dec 02, 2020 ]
A
It says 8gauge. But I'm currently running 4gauge with ferrules no issues.
[ ANTHONY  Dec 02, 2020 ]
A
8 awg. I would go with that! Obviosly the connection block is built heavy duty enough for 8 awg power & grnd cable. If your driving the RSM4,1200 near its limit a lot like i do you could develop heat in the PWR & GRND wires if their too small because the amp will be demanding more current. The imporntance of a good ground is often over looked ! Patience in making solid connections all the way around is a must !

Would i be able to wire 4 speakers @50 rms 4ohms and subwoofer 150 rms@4 ohms to this amp?

I connected 4 Polk speakers recommended for my car with no issues. Sounds great and crisp even with the top down on the highway.
[ MORTIMER  Nov 20, 2020 ]

Negative, this amp is 4- channel 4 Ohm stable or 2- channe 2 Ohm stable.
