Frequently Asked Questions - Reserve RSM1.2000D Soundstream

What is the recommended power wire gauge for the Soundstream Reserve RSM1.2000D?

Use 0 AWG for both power and ground connections to ensure sufficient current delivery. The remote turn-on wire should be 18 AWG.

Can the RSM1.2000D be bridged?

No, it is a monoblock amplifier designed to power a single subwoofer. Bridging is not applicable.

What is the minimum impedance load for this amplifier?

The amplifier is stable down to 1 ohm, delivering 2000W RMS. Avoid running below 1 ohm to prevent damage.

How do I set the gain correctly?

Set the head unit volume to about 75% of max, then adjust the gain until you hear distortion, then back off slightly. Use a multimeter for precise voltage matching.

What type of fuse does the RSM1.2000D require?

It requires a 250A ANL fuse (not included). Install it within 18 inches of the battery.

Does the amplifier have a subsonic filter?

Yes, it has a subsonic filter adjustable from 10Hz to 40Hz to protect your subwoofer from ultra-low frequencies.

What are the dimensions of the Soundstream Reserve RSM1.2000D?

The amplifier measures 10.6 x 18.1 x 2.2 inches (270 x 460 x 56 mm).”

Why is my amplifier going into protect mode?

Common causes include a short circuit, impedance too low, overheating, or under-voltage. Check wiring, speaker impedance, and ensure proper ventilation.

Can I use this amplifier with a 4 ohm subwoofer?

Yes, it will output 500W RMS at 4 ohms. You can also wire multiple subs to achieve 1 or 2 ohms.

What is the recommended wire gauge for the speaker output?

Use 8 AWG to 12 AWG speaker wire depending on power and distance. For high power, 8 AWG is preferred.

Proper system planning is the best way to maximize your amplifier performance. By planning your installation carefully you can avoid situations where the performance of the reliability of your system is compromised. Your authorized dealer has been trained to maximize your system's sonic potential. Your dealer is a valuable resource in helping you with your system design and installation.

Speaker Requirements

Each channel of your amplifier can easily drive 4Ω speaker loads when used in the stereo mode. When a channel-pair is bridged, the recommended minimum load impedance is 3Ω for subwoofer use, and 4Ω for full range operation. Although operation with lower impedances is not likely to cause immediate damage to the internal circuitry, the unit will most likely overheat, causing the thermal protection circuitry to shut down the amplifier. When the chassis cools down, normal operation will resume. Continuing to operate the amplifier under these conditions is not recommended and will reduce its life expectancy.

Most speakers designed for car audio operation are 4Ω impedance. Connecting two such speakers in parallel will result in a 2Ω impedance load as seen by the amplifier. Some subwoofer models feature a dual 4Ω voice coil design. Connecting these voice coils in parallel will result in a 2Ω nominal impedance, which is not recommended for use with bridged channels of your amplifier.

Power Connection Leads

Notes on the power supply

Connect the +12V power input lead only after all other leads have been connected. Be sure to connect the ground wire of the unit securely to a metal part of the car. A lose connection may cause a malfunction of the amplifier.

REMOTE: The unit is turned on by applying +12Volts to this terminal This terminal dose not draw heavy current like the two power terminal so a thinner connecting wire is acceptable. Standard 18 GAUGE is fine and the standard colour is yellow. If the radio is equipped with a power antenna control wire, it can drive this terminal. If the power antenna wire is already in use, you can still splice into it. With this method, the unit will turn on automatically with the radio. Use the power supply lead with a fuse attached whose value is the same as original fuse.

Place the fuse in the power supply lead as close as possible to the car battery. During a full power operation, Maximum current will run through the system. Therefore, Make sure the that the leads to be connected to the +12v and GND terminals of the unit respectively must be larger than 10-Gauge (AWG.10).
