Help with 2025 Tundra Audio

[WNCTracker]

This truck has been more challenging for me than other installs.
2025 Toyota Tundra SR5 without JBL.

Factory head into LC5iPRO to DS18 G1000.4D to front Morel Maximo 6 components and rear coaxial. Also the LOC using accubass is feeding a JL JD500.1 pushing two JL 8W3V3 subs.

Everything is connected and getting full sound so all electrical and plugs are good but First question is in LOC instruction is to set my “load select.” Crutchfield said 20 ohms, very little sound coming out. Multiple online searches and AI searches are all different. My current setting is 20k ohms but it still seems off. As instructed I turn all my amp gains down, turn off high pass filter on DS18 and increase factory radio to 75%. Then turn the output level up until the light comes on, which it didn’t do at max. That’s on channel 1 which is also set as “sep.”

Channel 2 is set as sum/bus to open channel 3 for the sub. Channel to going to the rear doors does the same thing, no light on the Loc. Turn gains up on amp and it sounds so so. I used 1000hz tone.

Channel 3, the sub channel I can’t get the accubass level to light until the threshold is totally maxed out using 50hz tone. When I increase the level on the LOC to get decent bass, my JL amp is clipping without gain increased. I’m assuming it’s getting too much voltage in from LOC or something but it seems like the LOC isn’t cooperating with me to get everything correct. First time ever using anything other than a $19 kicker LOC of a rear door wire and I’m so overwhelmed I’m regretting my investment.

Anyone willing to help out a very frustrated, non car audio expert with some hand holding? Crutchfield has always done me right, but their specs on the new tundras have been consistently wrong and sending me on wild hunts and working in circles.

Thanks for reading, I need a break.

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:

• 20 Ohm Setting: 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.
• 20k Ohm Setting: 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.

### 2. Gain Settings & Signal Level
Your signal levels and gain settings seem to be off:

• Initial Setup: Ensure your factory radio is at 75% volume. This is a standard for setting gains to avoid distortion.
• Adjusting Output: 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.

### 3. AccuBass Level
The AccuBass processor is designed to enhance low-frequency output, but getting it set right can take some iteration:

• Threshold Setting: 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.
• Testing Tones: Use a mix of tones (30 Hz, 50 Hz, and 100 Hz) while adjusting to understand how the system responds.

### 4. Clipping Issue
Regarding clipping with your JL amp:

• Line Level: 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.
• Amplifier Gain: Ensure your amplifier gains start at minimum, and increase them after setting your LOC properly.

### 5. General Troubleshooting Steps

• Wiring Check: Double-check all input and output connections on your LOC and amp.
• Grounding: Make sure all components are well-grounded; ground noise or poor connections can lead to this kind of issue.
• Settings Comparison: 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.

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.

WOW!!!
The bot actually provided very useful information.

Seriously. That was a BOT!?!? I’m dumber than I thought
