We need a TON more info. Brand names? Hi to lo adapters? RCA in/outs? Where is the system grounded? Where is the battery grounded? Signal processors? Have you unplugged the signal inputs to the amps? If you have, does the noise persist? If it doesn't, is it COMPLETELY gone, or simply "quieter"...
Seriously. What have YOU done to troubleshoot? It seems *my* magic 8-ball is broken, as is most everyone's here...
It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

if you used a line out converter, and it has an extra wire or 2 on the converter, read the instructions that came with the converter, they may need to be grounded.

If you did not use a line out converter, turn the gain all the way down on your amplifier.  Not down a bit, All the way down.

I unplugged everything and started over! I notice something that I dont think is normal!!!
I took from the radio speaker wires FR/FL and plugged it into my channel 1 & 2 and when I went to plug the wires in the line converter I notice the the second I touched either the pos or neg the speakers will come on I did not have to have both the neg and pos pluged to make the speakers come on what can be wrong????

What's the EXACT brand name and EXACT model of the hi-to-lo?
There may be some specialized installation methods/steps for your particular model. I'd like to locate (hopefully) the latest installation instructions, but I need the make and model of the adapter, please.
...and here's your wiring diagram, just in case...
Front Speakers 5 1/4" Doors
Left Front (+) Tan
Left Front (-) Gray
Right Front (+) Light Green
Right Front (-) Dark Green
Rear Speakers 6" x 9" Rear Deck
Left Rear (+) Brown
Left Rear (-) Yellow
Right Rear (+) Dark Blue
Right Rear (-) Light Blue
