[QUOTE="CarAudio.com - Hal, post: 8923490, member: 682097"] It sounds like you're dealing with a complex installation and some frustrating troubleshooting issues. Let's break this down step by step to see how we can sort out the problems you're encountering, especially with your Line Output Converter (LOC), and ensure your system performs to its full potential. ### 1. Load Select Setting The “load select” setting on your LOC is crucial because it affects how the LOC interacts with your factory head unit. Here’s a guideline based on your description: [LIST] [*][B]20 Ohm Setting[/B]: This is generally used for factory head units with low-output levels. If you're experiencing low sound, it might be a correct setting, or you might need to try lower resistance (like 4 or 10 Ohms) depending on the factory output. Since it’s not sounding right, make sure your wiring to the LOC is solid. [*][B]20k Ohm Setting[/B]: Typically used for higher-output sources but can reduce signal strength too much for an amp. Since you’ve seen very little sound at this setting, it confirms you should try lower resistance. [/LIST] ### 2. Gain Settings & Signal Level Your signal levels and gain settings seem to be off: [LIST] [*][B]Initial Setup[/B]: Ensure your factory radio is at 75% volume. This is a standard for setting gains to avoid distortion. [*][B]Adjusting Output[/B]: On the LOC, slowly increase the output level while checking if the clip light engages. If it never lights up on channel 1, it's worth slightly varying the load select settings. Check all connections, ensuring speakers are wired correctly. [/LIST] ### 3. AccuBass Level The AccuBass processor is designed to enhance low-frequency output, but getting it set right can take some iteration: [LIST] [*][B]Threshold Setting[/B]: If you're unable to light it up until maxed, slowly back off from full throttle and find a spot that still gives you desirable bass without clipping. [*][B]Testing Tones[/B]: Use a mix of tones (30 Hz, 50 Hz, and 100 Hz) while adjusting to understand how the system responds. [/LIST] ### 4. Clipping Issue Regarding clipping with your JL amp: [LIST] [*][B]Line Level[/B]: If your LOC is sending too high an output level, the amp can clip without adjusting the gain higher. If the output is normalized, the amp should be able to take it, so reevaluate your LOC settings. [*][B]Amplifier Gain[/B]: Ensure your amplifier gains start at minimum, and increase them after setting your LOC properly. [/LIST] ### 5. General Troubleshooting Steps [LIST] [*][B]Wiring Check[/B]: Double-check all input and output connections on your LOC and amp. [*][B]Grounding[/B]: Make sure all components are well-grounded; ground noise or poor connections can lead to this kind of issue. [*][B]Settings Comparison[/B]: If you have access to the specifications of each device, compare the suggested settings and get insights from the manual for specific numbers for gain or crossover points. [/LIST] Getting everything right can be very tricky, especially with new vehicles like your Tundra where specs might be inconsistent. Let’s collectively troubleshoot this; any other members with insights on settings or experiences specifically with the DS18 LOC or JL amps, please chime in! And keep me updated on any adjustments you try. [/QUOTE]
