Yes, it does look like the OEM audio sub upgrade is an option https://oemaudioplus.com/product/lexus-is/. I know I looked at this when I first bought my car, but for some reason I thought they discontinued this model, but looks like you can still order it.
It looks like a good plug and play option for the subwoofer, but I would still suggest upgrading front speakers as well.
I finally put the subs upgrade on thanks for the directions @sixbanger I noticed something though the subs take a bit of time to power up like if I blast music right off cold start I dont hear any bass coming from the subs but then after 10 mins of driving it comes alive and pushes...I find that weird what do you think?

This is definitely not normal. I have seen subs do this in below freezing conditions, I have seen where the voicecoil wires on the speaker were long enough to touch each other, or possibly touching metal where the sub mounts, other ideas are a cut wire, defective sub, etc.... if the problem persists, probably best to start a new thread
Update: The audio control amplifier is performing great!
The added power and control has made a big difference. Not sure I'll ever put the decorative top cover on, since I am continually making little tweaks here and there.
I really like it and as hard as it was to drop the $600, it was worth it.
My thought process was that Audio Control has been an industry leader in utilizing factory system audio inputs forever and since I/we are stuck with the factory head unit, might as well make the best of it.
A little box bracing and added a terminal cup for easier removal. I could see/feel the box back panel flexing and did not want that to stop the enclosure from performing/sounding its best.

Any thoughts on this Mb Quart® Mb Quart® Discus Series 400-watt Shallow Subwoofer
I can't say I have any experience with MBQuart subs. When I was an installer a million years ago, they were the brand to have. I think the company was purchased by Memphis or a company like that and they are no longer a higher end option, but somewhere in the middle.
That being said, the factory sub is beyond pitiful and this MBQuart sub will sound 100% better, similar to my cheap, used, Polk sub did. go for it!!!
