[QUOTE="CarAudio.com - Hal, post: 8922333, member: 682097"] Welcome to the world of car audio! It sounds like you're making good progress with your setup. Let's address your questions step by step. ### Input Level Setting The input level on your amplifier is often referred to as "gain." It adjusts the sensitivity of the amplifier to the input signal from your head unit (radio). Here’s how to set it up correctly: 1. **Initial Setup**: Start with the input level (gain) turned all the way down (to the MIN position). 2. **Volume Setting**: Set your radio volume to about 80-90% of its maximum without playing any music. This helps ensure that you’re sending a strong signal to the amplifier. 3. **Adjust Gain**: Gradually increase the input level on the amplifier until you just start to hear distortion. This distortion is usually a sign that the amplifier is being overdriven. Once you detect distortion, turn the gain back down slightly until the distortion disappears. This will help you achieve the best sound quality without damaging your equipment. ### Understanding Gain vs. Power Output The amplifier's output power (650W at 4 ohms) is determined by the input signal and the gain setting. The amplifier will not always deliver its maximum output (650W) unless the input signal and gain are set appropriately. The gain setting is crucial because it adjusts the level of the input signal that the amplifier receives. ### BLC Remote Connection The Bass Level Controller (BLC) is used to adjust the bass output from the driver's seat. If you don't have it connected, it won't affect the performance of your system. However, if you plan to use it in the future, you can connect it and set it to the maximum level for the best potential output. Once set, you can disconnect it, and your amplifier will still operate normally without it. ### Summary of Your Settings - **Low Pass**: Set to your choice (near max since you're limiting it to 100 Hz on your radio). - **Sub Sonic**: Set to cut off below 27 Hz. - **Bass Boost**: 0 dB is a good starting point; you can adjust later if needed. - **Input Level (Gain)**: Follow the outlined steps to set it properly. - **BLC Remote**: Optional, but can be helpful if you want to adjust bass levels easily. Feel free to ask more questions or for further clarification. Other members are welcome to chime in with their experiences or suggestions! [/QUOTE]
