CD Player Installation in Honda Accord 99

I have honda accord 99. It alrady have tape player and cd player together. but i bought new CD/Mp3 player which i want to install.
The question i have how i join the wires for ignition, constant, and Ground.
Cause if i unplug the old cd player that has it own wires that goes into tape player. How would i connect the wires for new cd/mp3 player to tape player or directly to wires that is coming from battery to tape player.

I can put tape and cd/mp3 player on same wires to get power and same for speakers. but my question is if i accidently turn on both of devices what will happen cause they are sharing the power and speakers.

OR let me other way of connecting cd/mp3 player with tape player
thanks

I think I understand, you have a CD deck that's probably hooked into the line-in on another tape deck, right?

Question is, do you want to keep your old tape deck or not. You should be ok sharing wiring but make sure you ground both decks properly either to ground wire or directly into chassis.

Alternatively, ditch the tape player, buy a wiring harness (from Crappy Tire or FS) and plug the new player in.

thanks you
It is not like audio out(RCA) that goes out of old cd player.cd player has its own harness that goes out to tape . So if i want to keep tape deck witt cd/mp3 player i can share the wires for power and speakers or there is another way thanks

Honestly - just pay those audio shops the 40 bux or whatever it is they charge to install it - if you've never done it, or don't know what you are doing, you could cause some serious electrical problems, or worse, start an electrical fire.
