Frequently Asked Questions - SPX1000X5 Stinger

How do I wire the SPX1000X5 for a 5-channel system?

Connect four speakers to channels 1-4 (minimum 2 ohms stereo) and a subwoofer to channel 5 (SUB+/SUB-). For front/rear bridging, use Front-Right + and Front-Left - for front, and Rear-Left - and Rear-Right + for rear. See the system diagram in the manual for a typical setup with four 4-ohm speakers and two 4-ohm subwoofers (2 ohms on sub channel).

What fuse size is recommended for the SPX1000X5?

An 80-amp inline fuse should be installed within 18 inches of the battery. Use 8-gauge power and ground wire.

Why is my amplifier going into protection mode (red LED)?

The red PROTECT LED indicates thermal shutdown or over-current protection. Let the amplifier cool down (thermal) or check for shorted speaker wires or low impedance loads. Cycle the remote power to reset. If it persists, inspect speakers and wiring.

Can I bridge channels on the SPX1000X5?

Yes, you can bridge channels 1-4. For front bridging, use Front-Right + and Front-Left -. For rear bridging, use Rear-Left - and Rear-Right +. Minimum impedance when bridged is 4 ohms. Channel 5 (sub) is mono with a minimum of 2 ohms.

What does the CONFIG switch do?

The CONFIG switch selects 2CH or 5CH input mode. Choose 2CH if your head unit has only two RCA outputs; the amplifier internally sums signals to drive all channels. Choose 5CH if you have dedicated front, rear, and sub outputs.

How do I adjust the crossover settings?

Each channel pair (Front, Rear, Sub) has its own crossover controls. Use the X-OVER switch to select HPF, FLAT, or LPF. Then adjust the FREQ knob (40-400Hz for main channels) or SUB controls (LPF 50-250Hz, subsonic 10-55Hz, phase, bass boost) as needed. A good starting point is 80Hz for both HPF and LPF.

How do I use the remote level control?

Plug the included remote level knob into the REMOTE LEVEL CONTROL port. It allows ±20dB of volume adjustment for the sub channel only. Press the knob to mute; press again to restore previous level.

What is the input sensitivity range and how do I set it?

The SENS (gain) control adjusts from 0.2V to 10V. To set it, turn the gain to minimum, play a test tone at 3/4 volume, and increase gain until you hear distortion, then back off slightly. Use a DMM or oscilloscope for precision.

Can I use high-level speaker inputs?

Yes. Cut the RCA connectors off the input cables and connect the wires to your head unit's speaker outputs. The amplifier accepts both low-level (RCA) and high-level signals.

What is the warranty on the SPX1000X5?

Stinger offers a 1-year limited warranty for the original purchaser from an authorized US dealer. It covers defects in materials and workmanship. Damage from misuse, improper installation, or unauthorized repairs is not covered. International warranties are handled by the local reseller.

System tuning

1. Install all system fuses.
2. Set the amplifier's input sensitivity controls to their minimum positions (full counterclockwise).
3. Set all amplifier signal routing switches according to your system's design.
4. Make preliminary adjustments to the crossover frequency, usually 80Hz is good starting point for high and low pass. It may be necessary to fine tune the crossover frequency later for the best overall sound quality.
5. If using an Remote Level Control, set it to maximum (full clockwise).
6. Turn the head unit on with the volume set to minimum.
7. Visually check the amplifier's has powered on by the power LED.
8. Check the condition of all other components to make sure they are powered up.
9. Set the headunit's tone controls, balance, and fader to the center (flat) position. Turn off any loudness or other signal processing features.
10. Set the volume control of the source unit for maximum undistorted output (on most headunits / media devices this will be approximately 7/8 of maximum volume). Use a very clear and dynamic recording.

1. Turn up the input level control until the speakers reach maximum undistorted output.

2. Repeat input level adjustments for all other amplifiers.

3. Reduce the source unit volume to a comfortable level.
4. Listen to various musical selections to check overall system balance. Compare front to rear, midbass to midrange, etc. If one speaker set is too loud compared to another, then its level must be lowered to blend correctly with the other speakers. The idea is to reference all speakers to the weakest set.
5. Fine tune crossover frequencies to achieve the smoothest possible blending of each speaker set.
6. With all levels set correctly, the system will reach overall maximum undistorted output at the volume level set in step 10.

Volume Control with Mute Function

The included volume control will allow for +/- 20dB of level adjustment from the remote based on the level set in the previous step.

In some instances this will not be enough to completely mute the output level depending on the amount of input signal. In these cases, a mute function allows for instant mute of output without adjusting the volume control.

To activate the mute function, press the volume control knob inward until it clicks.

To return to previous output level; press the control knob again.

Troubleshooting

No power: Check voltage at amplifier with a DMM (volt meter), B+ and REM (with head unit on) the voltage should register between 12.2V and 14.6V when using the attached ground lead of the amplifier. Check fuse at amplifier and at the battery. Use a meter to verify connection from one end of the fuse to the other, breaks may not always be visible. If the fuse is blown, check the power wire and also the amplifier for a short. If the short is in the amplifier itself, see your Stinger dealer. If no short is present, replace the fuse.

Power without sound: Turn the amplifier off and check all input and output signal cables and power connections. Check the speakers for shorts with a DMM (volt meter) or by connecting them to another audio source. After making sure everything is correct, turn the amplifier on again.

"Motor Boating" - the power indicator going off repeatedly when the audio system is on: Check the amplifier's connection to the battery. Check battery voltage. If low, recharge or replace the battery. Check all ground connections.

Power without sound and the PROTECT LED Is Ilt: The red PROTECT LED lights when the amplifier shuts down for either thermal or over-current protection. A high internal amplifier operating temperature will trigger thermal shutdown: after it cools about 5°C, the amplifier will restart. A shorted speaker lead or operation into unusually low impedance loads will trigger over-current shutdown: cycle power at the amplifier REM terminal to restore operation. Check for shorted speaker wiring or damaged speakers or crossover systems if over-current shutdown occurs.

No sound from one side: Check the balance control in the head unit. Check speaker connections. Check signal input connection.

WARRANTY:

LIMITED WARRANTY ON AMPLIFIERS

Stinger warrants this product to be free of defects in materials and workmanship for a period of one (1) years from the original date of purchase. This warranty is not transferable and applies only to the original purchaser from an authorized Stinger dealer in the United States of America only. Should service be necessary under this warranty for any reason due to manufacturing defect or malfunction, Stinger will (at its discretion), repair or replace the defective product with new or remanufactured product at no charge. Damage caused by the following is not covered under warranty: accident, misuse, abuse, product modification or neglect, failure to follow installation instructions, unauthorized repair attempts, misrepresentations by the seller. This warranty does not cover incidental or consequential damages and does not cover the cost of removing or reinstalling the unit(s). Cosmetic damage due to accident or normal wear and tear is not covered under warranty.

INTERNATIONAL WARRANTIES:

Products purchased outside the United States of America are covered only by that country's Authorized Stinger reseller and not by Stinger. Consumers needing service or warranty information for these products must contact that country's reseller for information.

Frequent amplifier shutdown with automatic recovery: This indicates chronic amplifier thermal shutdown because of operation at consistently high internal temperatures. High operating temperature can be caused by inadequate ventilation. Make sure you are not running a lower than recommend impedance. Also check for damaged speakers or passive crossover systems. Finally, chronic thermal shutdown may result from otherwise normal operation of the amplifier at elevated output power levels, which can be resolved by providing additional amplifier cooling, installing a higher-power amplifier, or reducing amplifier output level.

Very low output: Check your head unit's fader control or the amplifier's input sensitivity level. Make sure HP frequency control is not set too high and LP frequency control is not set too low at the same time.
