5.2 Ukuxhunywa kwezintambo
Refer to the diagrams below for proper wiring of power, ground, remote, RCA inputs, and speaker outputs.

Image 5.2: Rear panel connections for power, ground, remote, and speaker outputs.
- Amandla (BATT+): Connect to the positive terminal of the car battery using a heavy-gauge power cable (e.g., 4-gauge or larger, depending on total power draw) with an inline fuse located within 18 inches of the battery.
- Indawo (GND): Connect to a clean, unpainted metal surface of the vehicle chassis. Ensure a solid, low-resistance connection. Use a cable of the same gauge as the power cable.
- Isilawuli kude (REM): Connect to the remote turn-on output of your head unit. This wire turns the amplifier on and off with your car's audio system.
- Okokufaka kwe-RCA: Xhuma izintambo ze-RCA kusuka ku-pre- yeyunithi yakho yekhandaamp imiphumela ku amplifier's RCA input jacks. The HTG668BT features chrome RCA inputs.
- Imiphumela Yesipikha: Xhuma izipikha zakho ku- amplifier's speaker terminals. Observe correct polarity (+/-) for each speaker. The amplifier supports 2 Ohm stereo stable operation and can be bridged at 4 ohms.

6. Iziqondiso Zokusebenza
6.1 Ukuvula / Ukuvula
I amplifier will power on automatically when the remote turn-on lead receives a signal from your head unit. The 'PWR' LED indicator will illuminate. The amplifier features a soft turn-on/turn-off circuit to prevent audible pops.
6.2 I-Bluetooth Audio Streaming
To stream audio wirelessly:
- Qinisekisa ukuthi ampi-lifier ivuliwe.
- Sebenzisa i-Bluetooth kudivayisi yakho yeselula (i-smartphone, ithebhulethi, njll.).
- Cinga available Bluetooth devices and select 'Lanzar HTG668BT' (or similar name) to pair.
- Once paired, you can stream audio directly to the ampokokuphila.
6.3 Adjusting Audio Settings
Sebenzisa izilawuli ku- amplifier's front panel (refer to Image 5.3) to fine-tune your audio:
