Frequently Asked Questions - Horizon HXA100.2 ESX
What is the power of the ESX Horizon HXA100.2?
The amplifier delivers 100 W RMS per channel at 4 Ω, and can be bridged to obtain 200 W RMS mono at 4 Ω.
Can I connect 2 Ω speakers?
No, the minimum recommended impedance is 4 Ω per channel. Using 2 Ω may damage the amplifier.
How to install the amplifier in my car?
Connect the 12 V power supply to the +12V terminal, ground to the chassis, and audio signal via RCA inputs. Use a power cable with appropriate gauge (≥ 4 mm²).
What to do if the amplifier does not turn on?
Check the +12V connection, ground, and remote wire (REM). Make sure the fuse is not blown.
How to adjust the low-pass filter?
Use the LPF (Low Pass Filter) potentiometer to adjust the cutoff frequency between 50 and 250 Hz, ideal for a subwoofer.
Can I use the amplifier with a factory car stereo?
Yes, provided the car stereo has RCA outputs. Otherwise, you will need a high-level adapter (signal converter).
What is the overheating protection?
The amplifier automatically turns off if the internal temperature exceeds a critical threshold. Ensure adequate ventilation.
How to bridge the amplifier?
Connect the speaker to the CH1+ and CH2- terminals. Activate bridged mode if a switch is present (by default, bridging is automatic).
Where is the fuse of the device?
The fuse is located next to the +12V power terminal. Use a fuse of the same rating (usually 25 A).
The amplifier produces background noise, what to do?
Check the quality of the ground and RCA cables. Keep signal cables away from power cables to avoid interference.
