JK Audio Problems

So I decided to go ahead and ditch the Mopar RER head unit for a Kenwood 6190HD, which works amazingly.
When I purchased the car it had the 2009 JK Infinity speaker upgrade (7 speakers + Sub + amp) and it also appears to have the kicker speaker upgrade. However whenever I get to a high volume (32 bars and up) the speakers begin to "crack" and the vocals become distorted. It appears that when I also crank the bass up the problem occurs at lower volumes. Could this be happening due to not enough power from the amp to the speakers? And also I heard that the infinity amp filters out bass levels going to the sound bar? Id love to get more out of my speakers and feel more thump while driving .
Suggestions?
Are there any amps that would fit in the existing harness under the driver knee guard?
Or is this problem occurring from something else?

Yes... the stock amp/speakers suuuuuck hard.

Replace them with whatever. You have RCA pre-amps on your head unit so its an easy connection. New 4ohm speakers for the sound bar (coax) and 4ohm components for the front. New sub that can take some power and new amp(s) to match.

There are quite a few smaller amps that fit under the steering wheel like the stock one does. Its actually got quite a bit of room in there. Or you can look to mount them in the glove box or behind it. Some folks mount them under the seats as well.

Agree with this, the OEM speakers (even upgraded) are not very good. If you have the aftermarket head unit, that is the most important part to adding aftermarket equipment.

You could probably get some lower end speakers (still better than stock) that will work fine off the head unit power. However, as mentioned, if you want it to sound better, you will want an amp and speakers.

I pulled my system out of my last vehicle so it's older stuff. I have a Kenwood NAV radio, JL 4 channel amp for JL separates up front, Kenwood 6.5" coaxials for the sound bar. Kicker 10" sub in the rear with separate Precision Power amp. Both amps are installed under seats (1 under each seat).

As mentioned, they now have much smaller amps that you can put behind the dash.

So the infinity sound system with the kicker speakers suck? Haha XD
I can't redo the whole setup because of money but if I just had to get a new amp or a few extras then that would be fine.
The head unit has a wattage of 22 x 4 and max wattage of 55 x 4, do you think that would be better then just going through the amp especially since the amp filters the frequency for the sound bar? And would any channel amp work with the speaker set up or just a 7 speaker amp?
Edit: and I heard that 2ohm are louder then 4ohm speakers?
