a question or 2 :D

just wanna ask a few things about changing the colour of my interior thats all, since im such a n0ob

1) psx/ps1/ps2 , planning to install one but was just wondering where you guys place the machine (glove box?) and also how u go about hooking it up conceiling all the cables?

2) how would I go about changing the fabric on the doors? with the plastic and vinyl parts I know I can paint/dye it but how would I do the fabric? :S

3) the carpet or the fabric on the bottom of the car (where you rest your feet etc....), how would I change the colour of this? would I have to take out all the seats then do it?

thats all if I have more questions I'll post
