No tweeter sounds and distorted bass on components

Hello

JX500 is a subwoofer amp

JX360 is a amp for components and coaxial speakers

my JX360/2 having issues playing component/coaxial speakers, i have no tweeter sounds and just get distorted bass, any volume.

I have a JL Audio CP212 pushing 2 12" subs, connected to a JX5001D subwoofer amplifier

I acquired a 2 channel amp to run my JL audio component speakers, I also bought a 2nd component C5 set as i thought i had faulty speakers, I also bought another 2 channel amplifier to rule out faulty amps, still distortion and no tweeters,

The issue is:

Connected via RCA cables from my subwoofer JX500 amp to my 2 channel JX360 amp

Now when I connect any speakers my tweeters dont work and all i get is distorted bass. ive double checked all the speakers to my home amp and the speakers work fine

Its a very simple set up. added a 2nd amp, then got RCA cables from the pre-outs to connect to the 2 channel JX360 amp, connected to the low level input

So why i get distortion and why the tweeters dont work is puzzling

Im thinking its a signal or cable issue, but the cables look great,

can you advise please on what to do please??

You're not passing only low frequencies to your treble amp are you?

Wrong wiring layout.
The amp for the sub will, or at least should, filte the frequencies that are too high for a sub. Some will allow up to 100-120, but large, good sub will perform best bellow that. My previous Hertz sub would be best at 80Hz.
A CD with frequencies test should help.

no, my subwoofer amp has RCA going in to it thats been tapped in from the factory subwoofer amp i think, thats why im only getting a bass frequency, this was done by some company i hired to wire in my subwoofer and amp, what they should have done is tap into the feed from the head unit so i get a full range signal

theres no other way of getting a free range signal in to my amp now, the Audi A5 head is all built in and i wouldnt have a clue on how to connect to the head unit.

Getting signal from front door and rear door, using something like audiocontrol LC7I would allow to sort it out. Not cheap, but will be as close as possible to a proper full rang signal, plus the ability to do some adjusts.
