need help installing Pyle indash.

I got a pyle dvd player and indash screen.  I drive a 98 prelude.  I have a panasonic deck in there as well.  so i shared the powere with the deck harness. 

all the speaker wires are straight forward.  but there is  3 wires which connect to a fuse that is connected to the main box.  

they are

yellow( B+ batter), red(ignition)<--- can this be connected to the red with the deck harness? black ground.

power antenna as well.  i've connected these to all the right spot. except the red i did not use the ignition wire.

is there a method i should use in order to share power in one harness??all i did was wire them together.. should i splice them? 

does anyone have a DIY on this.. or could help me out.. thanks.
