I have a pioneer deck now in my car.. and my friend is giving me her sony deck so i just want to know how can i connect two head unit?

 

sell the sony

 

but her deck plays mp3s and mine doesn't .. then my deck has a lcd screen on it.. that is y i want to keep both

 

sell them both, and buy what you need!

 

Do you have a double DIN to do that in? I think only Toyota's and Nissans have a space big enough for two HUs.

Anyway, I have done this with a Cassette and CD HU. Here's my schematic


That requires a lot of relays and now my relays are starting to act up so I am going back to the drawing board.

What I am planning on right now is to us an FM transmitter from the cassette deck to send the signal to the CD deck.

You could probably do it easier and cleaner. Check to see if either of those decks has an input or CD changer controls. If either one does, you can connect them quite easily using the pre-amp out-put from the one to the input of the other.

I can be done . . . but I would be inclined to agree with the above, see if you can sell both and get all the features you want in one unit.

If your Pioneer is half descent it might have a set of RCA's labeled AUX, plug in a set of RCAs from the front or rear outputs of the Sony into the AUX of the Pioneer. Then ONLY wire the Red, Yellow and Black of the Sony for your power, don't use the line level speaker wires. There should be a separte volume control in your menu on the Pioneer to adjust the volume of the incoming signal from the Sony

If you don't have AUX on the Pioneer then Sony sells the AX-300 for around $150 which will allow you to use the RCA outputs of the Pioneer to plug into the Sony AV-300 which uses the Sony "bus" system to connect Sony stuff, or a set of headphones, DVD sound, playstation, and USB items if you feel like adding a laptop

 

thnx guys
