What Product Specifications Does Soundstream Technologies List for Amplifiers and Subwoofers?

Updated

Soundstream Technologies lists specifications on its product pages in a consistent format: amplifiers show max power, RMS power at 4Ω and 2Ω (plus bridged figures where applicable), channel count, and physical dimensions; subwoofers show driver size, max power, RMS power, and voice coil configuration; source units show screen size, smartphone integration support, and dash-fit notes. You can use these figures to compare models before buying, but you need to match them against your own system's impedance, space, and power goals rather than treating max power as a like-for-like number.

Amplifiers: What the Specs Tell You

The amplifier listings follow a fixed pattern. For example, the Stealth Series ST4.1200D is described as a 4-channel micro-amp with:

  • Max power: 1,000 watts
  • RMS power at 4Ω: 100W × 4
  • RMS power at 2Ω: 150W × 4
  • Size: 3" W × 1.50" H × 7.75" L

The ST4.500D, also a Stealth Series 4-channel micro-amp, lists 500 watts max, 45W × 4 at 4Ω, 65W × 4 at 2Ω, and 125W × 2 bridged at 4Ω, with dimensions of 3" W × 1.5" H × 3.75".

The RSM4-1200D is a compact Class-D 4-channel full-range amplifier with 1,200 watts max, 75W × 4 at 4Ω, 110W × 4 at 2Ω, and 220W × 2 bridged at 4Ω.

How to read these numbers

  • Max power vs. RMS power: Max power is a peak figure; RMS is the continuous rating you should use when matching speakers and planning electrical load. Compare RMS figures across models, not max figures.
  • Impedance matters: The same amplifier produces different RMS output at 4Ω and 2Ω. Check what impedance your speakers or subwoofers present before assuming you'll get the 2Ω number.
  • Bridged ratings apply when you combine two channels into one, typically for a subwoofer. The bridged figure is per bridged pair, not per channel.
  • Dimensions are listed so you can confirm the amp fits your intended mounting location — relevant for the "micro" and "compact" lines, where small footprints are the selling point.

Subwoofers: What the Specs Tell You

Subwoofer listings follow a similar pattern. The BXW-124 is a Bass Xtreme Series 12" subwoofer with:

  • Max power: 2,400 watts
  • RMS power: 800 watts
  • Voice coil configuration: DVC 4Ω (dual voice coil, 4 ohm)

The T5.124 is a Tarantula T5 12" model rated at 2,000 watts.

How to read these numbers

  • Size (10", 12") affects enclosure requirements and low-frequency output; the site lists size as part of the model name.
  • RMS power is the figure to match against your amplifier's RMS output at the impedance the subwoofer will present. A DVC 4Ω subwoofer can be wired to present different total impedances depending on configuration, so confirm the final load before matching.
  • Max power is a peak rating and should not be the basis for amplifier matching on its own.

Source Units: Screen, Integration, and Fit

Head unit listings include installation-relevant specs alongside audio features. The VRCPAA-106F and VRCPAA-106M are both described as floating 10.6" multimedia touchscreens with:

  • Apple CarPlay® and Android Auto® built-in
  • Fitment for standard 2-DIN dash kits/brackets
  • A screen roughly 30% larger than traditional 7" models
  • The 106F includes a DVD drive; the 106M is mechless (no disc drive)

The VRCA1-72W is a 6.5" 1-DIN digital multimedia car stereo with wireless and wired Apple CarPlay and Android Auto.

How to read these numbers

  • Screen size and mounting style (floating vs. standard) determine whether the unit fits your dash and how it sits in the console.
  • 1-DIN vs. 2-DIN is a hard fitment constraint — check your vehicle's dash opening before choosing.
  • CarPlay/Android Auto support is listed per model, including whether it's wired, wireless, or both. Confirm the specific model's support level rather than assuming it across the line.

A Practical Checklist Before You Buy

Use the listed specs to answer these questions in order:

  1. What impedance will my speakers/subwoofers present? Match it to the amplifier's RMS rating at that impedance.
  2. What RMS power do my speakers or subwoofers handle? Aim for an amplifier RMS rating in that range rather than chasing max-power numbers.
  3. Will the amplifier physically fit? Compare the listed dimensions against your mounting space, especially for micro and compact models.
  4. Will the head unit fit my dash? Confirm 1-DIN or 2-DIN compatibility and whether a floating screen suits your console.
  5. Do I need a disc drive? Choose between the DVD and mechless variants of the same screen size accordingly.
