Here are two different Kicker controls for the Sub, can anyone tell me which one to get......or does it not matter?

Do you have to get anything programmed at the dealer when installing into a Bose system? I saw this, and it made me wonder...Thanks!

Just sounds like a “we want you to pay us to install it” deal, since that notice only appears on the GM‘s own store and not any of the other vendors. Most people here have installed it themselves, including myself. I’ve never gotten anything programmed for it. Never heard of anyone else getting anything programmed for it either. I wouldn’t think much of that.

Cool, thanks! Mine arrives Monday, and I’m looking forward to getting it installed. Gonna try it myself. I picked up the bass knob today.

Anyone know which one for Part # 19417164 or does it matter?

Yeah, the Bose sub must be all of 4”. I guess short of redoing the whole system this was probably the best option.

Anyway, think I finally got this thing cracked.

Anyone who has tried it without the knob knows that the knob is both a bass killer, but it also makes the thing usable. So I’ve hacked it.

The knob is is just a 20k potentiometer with a 500 ohm resistor that forms the base resistance of the circuit.

The pot increases resistance from there, up to a maximum of roughly 20.5k ohms (20k pot plus the .5k resistor). So again, at the low bass setting, the amp reads a resistance of 500 ohms from the aux cable, and at max bass 20.5k.

Keeping this in mind, I had an idea. Using some little 10k resistors I had lying around in the parts bin, I formed a test. I removed the stock 500 ohm base resistor and replaced it with a 10k resistor. This effectively makes the baseline (knob all the way down) resistance 10k. That 10k measure on a stock knob is about midway. But the big thing was that the max was now up to 30k instead of 20.

And in the new max position, sure enough, the amp gain increased beyond what the original max would have been with the unaltered knob.

Taking it a step further, I soldered TWO 10k resistors in series and brought the baseline to 20k. Keep in mind that used to be roughly the max the amp would see from the knob, and now it is the minimum. So with the knob all the way down, it behaves as it did with the knob all the way up previously. And beyond that, the ceiling is now 40k. With this setting, I was able to reduce the bass on the head unit further and still really get some major production out of the sub.

I downloaded an sound app to confirm that the amp was reading and responding to the new range from the modded knob. But of course the difference was also easy to hear.

Attached are screen shots of the same part of the same song, same volume, same test location, same head unit EQ. Nothing too scientific but something to look at. One is taken at the low end on the modded knob (equivalent to the max of the stock knob) and the other at the new high of 40k, or double what the old one would have been. Measures about a 10db difference right near the sub.

You happen to have a Youtube how to for this mod?

I got the 46CXARC unit ($29.95) for my 19417165 Sub and it worked fine......pretty sure it would work for yours also.

Alright! I have a 2019 High Country with the Bose. The dealer had the truck for 7 hours but whatever. Kicker bass knob was routed myself and plugged in by the dealer. I left the lot sorely disappointed in the bass level. Honestly, max everything it wasn’t much deeper than the stock Bose system. Then I recalled a memory from this thread about the 6 switches on the amp. Mine was 1, 4, 5, 6 up and 2, 3 down. I went all up and BOOM.. there she was! What a complete change those switches made. I tried 1-5 up and 6 down and I’m on the fence as to which I like best. I no longer need bass settings maxed. Finally!

I just installed the Kicker system last week and agree it's a bit weak......

I have not yet checked the switches......how do you access them? Do I need to remove the sub to get to it?

Thanks for the information....

Pop the 4 screws off on the amp. On the back of the amp there is a rubber plug. The switches are in there. It’s my understanding that it comes from the factory preset with 2 and 3 down.

Great.....going to take a look this weekend.

Thanks for the awesome fast response!

Nice! I ended up settling one 1-5 up, 6 down. It seemed to be a bit smoother sounding.
