removing aftermarket hu

hi guys, this is going to sound weird but how do u remove an aftermarket deck?  My vehicle is shown in my signature.  My father had a sony head unit installed by some stereo place.  I got my sub and amp all hooked up and ready to go, but i just need the rca cables hooked up.  Thanks for the help guys.1993 toyota pickup all stock and pampered at 50,000 miles.

If I remember correctly you have to remove the 2 screws from the top of the radio dash as well as the bottom 2. Then take out the a/c buttons and the face to uncover 2 other screws. After taking those two out you will be able to take out that cover and then you will have 4 10mm bolts holding the radio in from the far back. Then again if they did not hold it down with the 4 bolts and then all you would need is the sony keys to pull each side of the radio out to access the back as you said to hook up the rca's.Sound Pressure

UPDATE: got the hu off.  there were two tab like things (which i poked at numerous times before) and finally figured out to push both of them inwards and pull out.  *slaps forehead*  well i got the stuff hooked up and the 8" bazooka really helped out the sound.  Now im ready to scope out some new dash speakers.  Anybody know the stock size?  I've checked everywhere and it says 4" BUT when i pulled them out they looked smaller...  hmm.1993 toyota pickup all stock and pampered at 50,000 miles.
