Quick question my boss head unit has 2 sub inputs on the back and I have it running to a ds18 2k amp and my dens are wired to 1ohm witch the amp dose support and I’m having an issue with the bass coming out of the subs is will only work when I have my rca wires one going into input and one going into out put in my amp and I cannot figure it out

It sounds like you're experiencing issues with how the RCA connections are set up between your head unit and your DS18 2k amp, which is likely affecting the bass performance. Here’s how you can troubleshoot and potentially solve the issue:

1. Correct RCA Connections:
- Typically, you should only connect the RCA cables from the head unit to the input of the amplifier. The RCA output on the amplifier is usually meant for daisy-chaining another amplifier (if you decide to add more subs or amplifiers in the future). Make sure you have the RCA cables connected from the head unit's sub output directly to the amplifier's input only.

2. Check Head Unit Settings:
- Ensure that the head unit's settings are properly configured for subwoofer output. Check for settings like "subwoofer level," "bass boost," and "LPF (Low Pass Filter)" settings. The LPF should be set appropriately to allow bass frequencies to pass through.

3. Amplifier Gain Settings:
- Adjust the gain on your amplifier. If the gain is set too low, you may not hear the subs properly. If it’s set too high, it can lead to distortion. Set it to a level where the subs sound clean without distortion.

4. Wiring Check:
- Ensure that your subwoofers are wired correctly and securely to the amplifier. A loose connection can cause issues with performance. Verify that they are wired in parallel or series as intended for a 1-ohm load.

5. Signal Ground:
- Check the grounding of your amplifier. A poor ground connection can lead to signal issues. Ensure the ground wire is connected to a clean, bare metal surface.

6. Inspect the Subwoofers:
- Make sure that the subwoofers themselves are functioning properly. If they have any physical damage or if the voice coils are blown, this can affect their performance.

7. Testing with a Different Source:
- If you have another source (like a different head unit or RCA inputs), try connecting that to see if the issue persists. This can help determine if the problem lies with the head unit or the amplifier.

After checking all of these, if you still encounter issues, you might want to consider consulting the user manual for both your head unit and amplifier for specific advice related to their settings and configurations.
