Parasitic drain from RADIO and SEO1 fuses..where to begin?

[Nickleahy23]

This is on a 2000 NBS Tahoe...

Ive had the same stereo set up in my truck for 3-4 years and never had a problem. The last few months Ive been getting a dead battery here and there..I was pulling 1.5A from the SEO1 and RADIO fuses, pulled them and I was down to .07A. Without these fuses i get limited use on the cluster and the radio obviously doesnt work. Where do you think I should begin? Possibly pull the screen out and try hooking up a stock one to see if thats causing the draw? Ive heard its a fairly common problem to have those 2 fuses/circuits causing a drain..any ideas where to go would be great.

2000 NBS Tahoe.. Ive been getting a draw on my battery and i traced it to these wires..SEO1 and RADIO both have something to do with these..what are these wires for? do they go to the speakers? when i unplug this plug, my draw goes away.

The truck came stock with a sub in the rear and some amp somewhere. I have to have an ORANGE wire hooked to my remote wire to make things work, which im guessing is to power the built in amp, and for some reason its staying on (im guessing).

Any ideas?
