## Overview

The Soundstream ST4.1200D is a compact Class D amplifier designed for high-efficiency, low-noise audio performance. Measuring just 19.7 x 7.6 x 3.8 cm and weighing under 1 kg, it fits easily in tight spaces like under seats or dashboards.

## Description

Don’t let these little monsters fool you. The latest and greatest of class d full range technology allows us to Pack 10 lbs of kick your ass in less than 2 lbs chassis. Once regarded as “dirty power”, class DS stable performance, thanks to high power capability, maximum efficiencies, and low tolerance components, rivals traditional full range applications. Minimal power requirements, Ultra micro Footprint, unbelievable sound quality, and easy install make Stealth amplifiers great for any car, Motorcycle, boat, or off-road vehicle.

Review: I chose the Soundstream ST4.1200D running my front and rear mids/ highs separates (Hertz brand) to replace a JL Audio JX 400/4D that was cutting in and out and producing static. I've had good experiences with Soundstream amps in the past and after reading many favorable reviews decided to give them a shot again. The stealth series is super convenient if space is an issue, and will easily fit under a seat, glovebox or rear deck of a car. I was surprised at how small it was due to it being Class D & the type of wiring harnesses it comes with. I used the supplied RCA to wire plug adapter since my existing system used RCA cables, and hooked up to power, ground and remote turn-on (if your using speaker level inputs you can do without the remote wire). It has LP/HP crossover switch but I'm running it full range since my head unit has crossover and EQ built-in. The manual shows a wiring schematic but did not include individual wire colors in it so I simply looked them up online (They are standard colors, same as almost every speaker wire out there, White, Grey, Green & Purple with negative having a black stripe). I initially turned the gains to halfway point, but after testing, volume was too low, I had to turn them all the way to max for my particular system. Sound is clean, clear at both quiet and loud volumes with pretty low noise considering my gain is at max, noise is less than the JL Audio it replaced. More expensive amps will have screw lug terminals and jacks integrated into the chassis, whereas the Stealth uses wire harnesses for all inputs, outputs and power, so butt/ splice connectors will be needed. Overall I am pleased with my purchase and would buy this amp again.
Review: Bought this little amp for a ‘72 International Scout II as I wanted something small enough to fit under the passenger side dash so it’s hidden when the top comes off every summer. Fit perfect and pushes a great note through the Rockford Fosgate 6.5’s and the other 2 channels are bridged to a single 8” sub

## Questions & Answers

**Q: Does it have a remote bass control**
A: It has a port for the remote bass, but I had to purchase it separately.

**Q: What gauge do I need for power? Page 9 does not have a chart.**
A: It pulls 100+ to 200 more watts than rated watch tube with on a amp dyno i run the 3600 watt sound stream extreme power on 3 8" skad 2600 watt subs and this stealth on 4 kicker 6×9's 2 6.5" components 4 twesters and 4 for 2.5" horns and my amps arent maxed out but it makes over 98 db and enough bass to make yiur stomach hurt all on 4 gauge

**Q: This may have been answered already. But my question is I’m installing this on my wife’s 2014 street glide. What gauge wire do you use for power?**
A: I used 8 gauge

**Q: Which wires are for bridged 4 ohm?**
A: I had the same problem with the 1000 watt version of this. Look at the picture on the end of the amp, not the picture in the instructions to wire for bridging.

*by S***Z on 9 October 2022*

Have this installed in my Ford Ranger Single Cab, needed a small amp for a small truck. It's powering a set of Kicker CS-Series 6-1/2"Components and a set of Alpine 6x8's in the rear. Sound quality is fantastic and loudness is very loud. Amp installs just like any other amp, not easy or hard, you'll know what to do. Instructions are pretty weak but you can get by with them if this is your first time. Dial adjustments are easy to use and pretty accurate. Took my truck from California to North Carolina, 3500 miles, blasting music all the way and amp never skipped a beat. Have had other amps cut out due to overheating but not this one. Would highly recommend if you're looking for a small compact amp to push some serious power.
