Head Unit frequency range as a limiter

[shortnugly]

Slowly planning an upgrade for a 2017 Honda CRV. Keeping the OEM HU and grabbing the high level signal for feeding two amps and new speakers.

Recently picked up an Audiocontrol LC2i LOC and saw the freq range for that unit as 33hz-100khz. So that got me thinking if I stay with this LOC, I'll have to plan around the 33hz limitation. Then I thought what does my OEM HU output? I couldnt find any info on Honda forums.
A general inquiry on AI forms show that most audio manufacturers HUs generally produce 20hz - 20khz.

So if I were to keep my LOC, no need to pursue anything lower than 33Hz as my LOC wouldnt pass that. I researched other LOCs that can process lower and higher freq ranges.

But the main question is: can I find out what my HU freq range is? If my HU doesnt produce anything lower than 40hz, for example, no need to consider another LOC.

Maybe it's an off the wall question. Any ideas?

To determine the frequency range output by your 2017 Honda CR-V's OEM head unit (HU), you can consider the following approaches:

1. **Consult the Owner's Manual**: Sometimes, the owner’s manual contains specifications about the audio system, including frequency response. Check if there's a section on audio performance.

2. **Contact Honda Support**: Reaching out directly to Honda customer service or a local dealership can provide you with specific information about the audio system's specs, including the frequency response of the OEM HU.

3. **Check Online Forums**: While you mentioned you couldn't find information on Honda forums, you might want to explore forums specific to car audio or CR-V enthusiast forums. Sometimes, users have shared their measurements or experience with the OEM systems.

4. **Use an Audio Analyzer**: If you're technically inclined, you could use an audio analyzer or a smartphone app that measures frequency response. You would need to play a frequency sweep through the OEM HU to see what frequencies are produced.

5. **Research OEM Audio Performance**: Generally, OEM head units are designed to cover a range from about 20Hz to 20kHz, but it can vary. If you find that most Honda audio systems fall within this range, you might assume your HU does as well until verified.

Since your concern revolves around the compatibility of the LOC (Audiocontrol LC2i), if your HU does output below 33Hz, you might consider other LOC options. However, if it indeed doesn’t produce frequencies lower than 40Hz, then your current choice of LOC should suffice.

If anyone else has specific experiences or information regarding the OEM HU frequency output for the 2017 Honda CR-V, feel free to chime in!

The HU probably outputs 20hz-20khz. You could test it yest tones and o-scope or test tones and a speaker/sub that goes down to 20hz.

33 hz is fine. you'll never notice the difference.

33Hz is not a hard cutoff "cliff", but it's still an 18dB/octave drop. The main outputs should be full frequency.
How about using the main out instead of the bass out, and crossing over with your sub amp instead?

Is your head Unit the touchscreen and what model is the CRV? EX, EX-L, Hybrid EX, Hybrid EX-L, Hybrid Touring, LX, Special Edition, Touring?

Everything I see shows an at minimum a four channel factory amp at about 160w. (40x4).

Thanks all. I have a CRV EX, no factory amp. Still working on getting more info on OEM freq range.

I'll look into getting the app for a sweep measure but my stock speakers are so crappy I dont think they could reproduce anything below 80hz.

I like the idea of just using the LOC main out and crossing over with the sub amp.

Amps are: Arc Audio 2050 CXL 2x50 @ 4 ohm no RCA outs--- and Kicker DX 500.1 300 @ 4 ohm with RCA outs
The Kicker has an infrasonic filter I was planning on engaging at 20-25hz. Because it's a smaller sub amp, the plan was to fiberglass a sealed enclosure with about .7-.8 cu ft and run a L7T or some small enclosure sub. I dont think I could get that sub down past 30hz anyway (different rabbithole) so the loss of the lower freq may not matter.

I'll report back with what I found. Appreciate the help.

Should be pretty straight forward. Front speakers "should" be getting full bandwidth from the radio (even if they can't reproduce all the frequencies) so if it were me I would tap into the front speakers with the LOC.
