Help with upgrading TJ sound system

I have a 2003 Rubicon with console sub. I am looking to upgrade the sound system. I don't know much about sound systems so I need some advice.

I am considering an alpine HU.
I like the idea of the alpine KTP-445A amp. It looks quick and clean to install.
I will upgrade the dash and sound bar speakers.

My concern is the console sub. Will it work with the kip-445a? Or is that too much power for the stock sub ( which I think has a little amp in the console)?

My other idea would be to build a sub box into the console and add a 8 inch sub. Would that work using the existing wiring? Assuming I ditch the little factory amp in the console.

Any thoughts or advice would be appreciated!

I just recently upgraded my sound system. I'm an Alpine follower and in my old vehicle ('93 4 Runner) I had installed a CDA-7998 and it's built in features with Orion amps.

Now that I've gone to the TJ, space is more of a challenge.
I ended up installing the CDE-HD149BT, was a not sure how I would get used to this new H/U, but soon found out that it communicates to my phone and with the Alpine tuneit app. This allows you to make adjustments to the ParaEQ, Time Delay and X-overs then save the settings on your phone.

I adjusted the time delays for the drivers location and then run it in the Front Spatial mode.

I then installed the KTP-445A amp int dash below the h/u. Very impressed with this combination. It drives the little 5.25" speakers very loud and cleanly.

In the overhead pods I replaced the stock speakers with Kicker 40CS54 ( they were cheap) packed it with polyfill and have the freq. cut off in the deck set at 18bd @60hz.

In the dash I replaced the speaker pods with the 5 1/4" aftermarket pods and filled with polyfill also. They have a set of Alpine SPR-50 with 18db @ 80hz cutoff.

I would like to add a sub, but I'm not in a hurry there. I value my space for camping and off roading equipment.

I just got done with my 03' TJ radio install.

Receiver choice:
Bluetooth Car Stereo with CD Player & USB | MEX-XB100BT | Sony US

Went with this receiver due to the excellent reviews and since the cold winter months are here, i didn't want to fuss with putting an external amp in the Jeep and upgrading the wiring, this one comes with an integrated amp rated at 40 RMS per channel.

I put in Polks in all four corners with Polyfill and went ahead and replaced the center console sub with a Kicker 6.75" DVC 2 ohm subwoofer.

I didn't want to take up any extra space and so far, I'm quite pleased with the results. I'm sure if anything lacks when I have the top off in the summer will be rectified, but i must say hitting some low bass from Bliss Eso sounds pretty darn good!
