Do rear speakers take the same signal that front speakers do?

This question may or may not be stupid, however I'm having trouble finding info online.

Does a typical car stereo deck output the same signal to the rear speakers as it does to the fronts?

I'm considering getting rid of the rear speakers in my Accord altogether, and instead considering placing my JBL's where my front speakers currently are, and angling them to face towards the rear of the car a little more. I have heard that car head units typically only use two channel audio, and that the rear right outputs the same sound as the front right, and same with the left.

Would losing my rear speakers lose any sound signal for me?

2ch stereo, so yes the fl/rl play the same thing, same as fr/rr play the same thing.

Same signal, yes - losing the rears altogether is going to vary by taste.

A bit of rear-fill gives a more immersive feeling to music in my opinion...

I'll second that. I'm also a rear-fill person.

Third. Rear fill is necessary IMO, even with a loud sub stage.

Rear fill is good.. if you send to it correct type of signal. A typical surround sound systems sends the time-delayed L-R difference signals to the rear speakers so that they create a sensation of ambiance without interfering with the sound stage. My theory is that people who think that sending a plain stereo signal to the rear speakers makes the sound system sound better simply got used to a flawed sound.

You are correct. Most car stereos send plain stereo signal to the rear speakers, the same that's sent to the front. What this does is draw the sound stage to the back of your car. In a properly setup front stage, with properly placed, equalized, and time aligned speakers, you will never miss this type of crude rear fill.
