Hi

I bought a crossfire roadster last March and have been surfing this site since then.

My car has an aftermarket Alpine stereo that is impossible to read the screen in daylight. I wish to revert to the factory radio (or upgrade to a readable marine grade head unit). The original harness plugs to the stock radio is gone, someone cut off the wires and attached on plugs. The rear speakers produce no sound. I found the rear speaker outputs from the Alpine head unit are not connected. (Green and violet wire pairs).

I did purchase an original Infinity radio, minus any harness/plugs and antenna adaptor.

questions:
does anyone have the original stock radio plugs that you are willing to sell?.
Are the green and violet wires in the crossfire harness preamp inputs or speaker level inputs?

thanks in advance

Quesrions:

 

Lots of threads here on the subject. I wanted Bluetooth so went with a Clarion M303 and it works perfectly.

 

Mine is a YL...YL/VT....BL...BL/BR...these are from stereo to amp. YL is right rear speaker - . . YL/VT is left rear speaker +. BL is right door speaker - . BL/BR is left door speaker +

 

Excuse my question about the rear speaker leads being violet and green. These are from the adaptor connecting the Alpine and factory wiring. Upon further analysis these connect to null (unwired) connectors on the factory harness.

What I am not clear on is where to connect the rear speaker leads from the Alpine head unit to the harness so I can get some bass.

 

Thx for the color coding info Steve

What is the color "DG" as in "RD/DG"

 

There is no fader on the original head unit. The way it's set up , there was no real bass ,thumping from the system. Many have found if you use the factory amp, the need to put a resistor in line at the door speakers. That way it gives you a better sound from the rear speakers. There's lots more info available under the technical section of the forum.

 

I have been reviewing other threads, but I am unclear on whether the amp rear speakers are speaker level input or preamp level input.

I do plan on installing the resistors on the front speakers.

I now wonder if the rear speakers are toast

Agan many threads (including schematics) but in short: Dark Green & line input (4v is good). Also the amp is stereo but wired for mono and jumpered at the amp. Connectors can be found at any recycling center.


Want the mate to a scosche vw03b.

 

The radio is not wired mono, it is stereo as right and left are separate, there is balance control. There is no fade because front and rear are not separated. There is a PDF with instructions to rewire for four channel. The amp is four channel but the rears were not separated.

 

Does anyone know if the front door speakers are 4 ohm or 8 ohm? I do not want to take my door apart to find out

 

4 ohm. What model Alpine did you take out ?

 

Is this any help? The pin outs are from the OEM radio.

 

took out cde 121 c receiver

 

OK, thanks. Was hoping it was a IDA-X001 - they are getting very rare and I could use a new face plate.
