I spend a good amount of time playing with amp settings but ended up using my own vs the auto tune ones.

This is sick!! I need to look into fitting a 10” in my box. I have an 8” right now but I miss having the 10” from my last truck. May I ask what cu. ft. of air space your sub requires?

first of all, congrats, nice system. heck of a grille on that sub, hehe.


uh... what? that looks like a kicker key 500.1, I have one also.

there aren't any amp settings other than gain (edit) and crossover frequency. you can't tweak the EQ or DSP at all it's just auto-tuned or off. did you have issues getting the automatic tune to complete? because, I've had issues with that on key series amps, also. it can be a PITA.

you definitely want to use the autotuned dsp and you should not have to mess with the gain afterwards. the dsp will fill in the very low bass quite well, and it'll remove any peaks due to the sync3 source, cabin gain, resonance, etc.

Yes you are correct. I spent a lot of time listening more or less after running the gain track and the sweep track. I wasn’t happy with the adjusted setting so o currently have them off. I also didn’t have my spectrum analyzer at home. I may give that a go in my free time. I have the gain and crossover adjust to where my ears think it should be (I think over the years I have decently calibrated ears lol) I didn't have an issue with getting the auto tune to complete.

Which tune files did you use? What dB?

-5dB now, after using 0dB originally. After a month it sounded like my sub broke in and that's when I retuned with the -5dB.

Make sure you have the sync3 unit on stereo, no speed volume adjustment and tone controls flat. Then set the volume to like 23-26 and run the calibration. It should complete and in my case it was a massive improvement over no DSP correction.

I did the zero dB and was set at 23 for volume. I’ll let it break in some more and try again.

Did you ever get the happy chime? I can't remember exactly my settings but I do remember it was not the first thing I tried... Or the 5th, lol.

The key 200.4 is even more picky.

Installed a Kicker L7R 10” with a Kicker Key 500.1 last night.

install was pretty straight forward. I used a 6” powersports amp kit and hooked up power and ground right at the battery. I used high level inputs of the key to utilize signal sensing (no need to run a remote wire).

I removed the light switch and mounted the bass knob in the black space. It’s a good location and doesn’t look out of place.

I spend a good amount of time playing with amp settings but ended up using my own vs the auto tune ones.

When mounting the amp to the back wall I used two existing bolts and just elongated 2 mounting holes on the key. I used some aggressive double sided tape on the back side as well and it’s super solid.

Special thanks to Chris at Sound Decisions. After the transaction I had my box in 2 days. High quality and made this install easy.

Love your setup! What’s your take on “supposedly”only being able to have a 30 amp maximum draw on the system? Im assuming your having no issues with the kicker key 500.1 drawing a max of 91 amps of current. Did you replace the other speakers as well? If so, what did you use?
Lastly, do you have a video of it playing?
