Hooked up Optimus 200w. amplifiier w/ MTX Thunder 5000 speakers, using RCA cables from rear output jacks. Sound comes out of factory speakers just fine, but MTX speakers don't move or make much noise. Is it something to do w/ POWER IC setting, or is there another setting that I should try? Any info to help solve my problem would be greatly appreciated!

You didn't say whether the player is connected by 2 RCA cables (analog) or by digital cable. If by RCA, does the player have a headphone jack? I had a player once with a piece of a headphone that broke off inside the jack, muting the analog outputs.
If you connected R/W RCA cables to the AUDIO OUT RCA jacks on the rear of the TV and connected the other ends to the TV AUDIO IN jacks on the receiver, you should be able to select an input on the receiver that will deliver sound to the Bose speakers. If you went to TV setup and selected external speakers, you directed output from the TV amplifier to external speakers which is not what you want.
Make sure you have a proper ground wire connection. The ground wire should be connected solidly to the vehicle chassis in a paint-free location. If it is loose or there is paint t the connection site, you will have problems with the amp output. Also check the speaker wires to see if they are touching the vehicle chassis. This will cause a short circuit and you will not have output from the amp. Finally, check the leads from the head unit. They should be RCA cables, and should have a good connection to the amp.
Extra speakers without having the external speaker jacks in the rear is definitely a NO NO. The surround sound is used by connecting the RCA jacks from the TV that say Audio Out to the surround sound audio input on the receiver.. The RCA cables are cheap, you can get them at Home Depot ect....
Did you run your power and remote wires the same route as your RCA cables? If you dont run the RCA cables on the opposite side of the power and remote you will get feedback through your speakers. I run my power on the side closest to the battery along with the remote ( passenger in my case) and the RCA cables should be on the opposite side( driver side). They say the power current will create a disturbance in the RCA cables that you would hear as feedback. Hopefully this will help you.
This is common with pioneer head units, the rca jacks are not properly grounded and this lets engine noise come through the rcs cables. This thread explains a fix http://www.caraudio.com/forum/showthread.php?t=337644.
