Thanks everyone with replies! I checked voltage on RCA outputs with AC volt meter, and guess what? There is output and its proportional to Volume set. So my RCA outputs are not dead. But speaker still not playing. Which leads me to a thought that amp is needed. Seems like you right, RCA output incapable of driving the speaker of stock sub. What confused me is that stock head unit driven sub alright, but I think its because there is internal amp in head unit itself.

Now, with that said, any suggestions for little compact amplifier to drive 6x9 speaker as output and have Sub-RCA connector as input?

I plugged in my computer to subwoofer wiring in car, plays nicely even without amplifier! So RCA will drive a speaker. Opposite, I plugged in RCA from AVIC into other external computer's speakers, which are amplified, and got NO sound.

STILL UP!

OK. I solved the bypass problem. Grounding black wire is important. So I don't have "brake lead" problem anymore! Yay! I also noticed that doing so also grounded my RCA shields as well. Is that normal?

Now the only thing left to do is to repair my Subwoofer pre-out.

What I did to make Sub work.

1. I don't have amp. This should eliminate part of issues.

2. Tested wires leading to sub speaker. Attached RCA male connector to sub wires, plugged it to iPod via adapter, and I DO hear sound in my trunk. So Sub speaker works and wiring is okay!

3. Plugged my Sub RCA to red Subwoofer output on RCA harness of AVIC D3.

4. Turned on Subwoofer settings in AV Menu. It is in ON position, but I still don't hear sound from the trunk.

Please, I need your input on where to start with that. Any suggestions on repair service? Or maybe I can do it myself?

So um... Nobody knows? Comon, guys. I searched all over the forum and found some messages related to my problem.

So basically there's a fuse inside the D3, that probably went out in my head unit. The complicated fix is to disassemble the whole unit, locate and replace fuses. The simple fix is to connect RCA shields (outer wires of all RCA's) to the ground.

Just like on that picture:

BUT IT IS DANGEROUS, BECAUSE IT CAN FRY THE UNIT at some point.

People also describe some generator whine in their speakers, I don't have any whine. The sound is clear and sharp, but not coming out of RCA's.

So how do I get the output out of Subwoofer RCA? I need your help guys!

Now, as for bypass. I have brake lead error message popup. I got thru all steps on this site except last one. I don't get it, why do I need to ground Black wire on harness? Isn't it already a ground? Anyways, what might be the case?

I have Pioneer AVIC-D3 bought off ebay. The unit came with RCA outputs being dead. Other than that, the unit works great. I tried to plug in my sub to the Sub-woofer output RCA connector, The sub is dead silent. Front Output and Rear Output RCA's are dead too. Camera input works great. Is there a way to fix the unit?
