How to troubleshoot Soundstream Stealth 1200D that will not power up?
If your Soundstream Car Amplifier won't power up, ensure you have a solid ground connection and battery power at the (+) terminal. Inspect all fuses, replacing any that are blown. Also, check that the Protection LED is not lit.
Why does my Soundstream Stealth 1200D Car Amplifier have distorted sound?
If you're experiencing distorted sound with your Soundstream Car Amplifier, first, check that the input level control matches the head unit's signal level, keeping it as low as possible. Verify that all crossover frequencies are correctly set. Finally, inspect the speaker leads for any short circuits.
What to do if the protection LED comes on in Soundstream Stealth 1200D Car Amplifier?
If the Protection LED on your Soundstream Car Amplifier is illuminated, check the speaker leads for short circuits and ensure the speaker load isn't beyond the minimum. Try removing the speaker lead and resetting the amplifier. If the LED remains on, the amplifier may be faulty and require servicing.
Why is my Soundstream Stealth 1200D Car Amplifier getting very hot?
If your Soundstream Car Amplifier is overheating, verify that the minimum load impedance for your amplifier model is correct. Ensure there's good air circulation around the amplifier. In some cases, you might need to install an external cooling fan.
What to do if my Soundstream Stealth 1200D has no output?
If your Soundstream Car Amplifier has no output, check that the RCA audio cables are correctly plugged into the proper inputs. Inspect all speaker wiring. Also, check the headunit output and the amplifier level setting.

Official documentation for the Soundstream Stealth Amplifier Series.
Connect speakers/subwoofers, check polarity. Never connect to chassis ground.
Connect to positive battery terminal via fuse/circuit breaker. Protect with fuse.
Turns amplifier on when (+)12 volt is applied. Connect to head unit remote lead.
Connect directly to vehicle frame (bare metal). Use shortest distance, consider larger cable.
For source units with RCA outputs. Minimum 200mV level required. Use twisted pair cables.
For speaker level wiring. Use when RCA outputs are unavailable.
Connect remote controller to adjust subwoofer amplifier volume from driver seat.
Matches amplifier sensitivity to source unit signal voltage. Range 200mV-5V. Not a volume control.
Selects low pass x-over frequency. Adjustable from 40Hz to 220Hz.
Filters unwanted low frequency from 10Hz (OFF) to 50Hz. Increases woofer power handling.
Boosts wanted frequency and level. Frequency 30Hz-90Hz, Level 0dB-12dB.
Adjusts speaker output phase from 0 to 180 degrees for system phase matching.
Controls frequencies for front channels. Options: Low Pass, Full Range, High Pass.
Controls frequencies for rear channels. Options: Low/BandPass, Full Range, High Pass.
Boosts bass level by 0dB, 6dB, or 12dB. Boost frequency centered at 50Hz.
Switches rear channels' signal path. 4CH requires all RCAs; 2CH uses front channels in parallel.
Controls frequencies for STL2.350 & STL2.560. Options: Low Pass, Full Range, High Pass.
LED lights up when amplifier works properly.
Red LED lights up/flashes for faults. Disconnect and resolve fault.
Soundstream Stealth amplifiers can be stacked. Plan installation for air circulation.
Check drawing to mount the bottom amplifier.
Prepare side bars by inserting rectangle nuts.
Insert side bars into heatsink fins and fasten with screws.
The bottom amplifier is now mounted.
Stack two amplifiers, preparing side bars and ensuring a 1/4 inch gap.
Mount the third pair of side bars on the top amplifier.
Now you have stacked two amplifiers.
Select cable and fuse according to the provided table.
Connect ground cable to bare metal frame. Use nut/bolt, same size as +12V cable.
Connect remote terminal to head unit remote output using 16 gauge wire.
Connect fuse holder within 18 inches of car battery.
Connect all inputs with high-quality cables. Connect Remote Control if needed.
Insert fuse(s) into the battery fuse holder(s).
For 2-CH and 4-CH, bridge channels using Left '+' and Right '-' terminals for subwoofers.
Check ground, battery power, fuses, and protection LED status.
Check for speaker shorts, load limits, and reset amplifier.
Check RCA cables, speaker wiring, headunit output, and amplifier level settings.
Reset level control and check crossover settings.
Check RCA cable for shorts to ground and amplifier grounding.
Set input level low, check crossover frequencies, and check for speaker lead shorts.
Check minimum load impedance and ensure adequate air circulation.
