  1. It's a pins #2 and #6 (blue/red and blue/yellow) in D12 connector. Yes, I already replaced head unit for an aftermarket and after you mentioned "25 watts per speaker", I realized why my front speakers are really silent - it's because I had Scosche Wiring Interface hooked up and it was reducing the output in order to work with factory amps. So I took out front door amps, then bypassed this scosche interface and wired front speakers directly to head unit. And I reused existing wires for that. Then I studied the schematics a bit and found out, that pins #1 and #3 in D12 connector are for the tweeters. So I removed all other wires and left only #1 and #3 in D12 connector. And everything is working fine now! I can tell, that front speakers are now even louder than the rear ones, so I had to set the fader on rear 7. This is how all things look like: All the mess with the wires and duct tape doesn't look nice, but at least it works! THANK YOU so much for the help! Really appreciate that!
  2. Hello guys! Sorry for the silence over the past few weeks - I had an injury and couldn't work on this, but now I feel better and tried to bypass the amp today. So I managed to take pins #2 and #6 out of the D12 connector and wired them directly to the speaker. And the speaker worked! But it was really (I mean REALLY) silent compared to the rear ones.. I read somewhere, that bose speakers' impedance is just 1 Ohm, while the most of aftermarket speakers usually are 4 Ohms. Just out of curiosity I took one 6 Ohms speaker from my home stereo and hooked it up in the car, but the result was basically the same - not very loud.. If I buy new 4 Ohms speakers, will they be louder? How do you think?
  3. Got it, thanks! I'm going on a road trip soon for a couple weeks and when I'll be back I'll try to bypass the amp and let you know the results!
  4. Where can I find that relay? Maybe it's easy and cheap to replace it? When I was measuring the voltage, the connector was disconnected and I probed at the front. Does it make any difference? I'm ok to buy a new speakers if they'll work fine. About which particular 2 wires are you talking about? Red and black?
  5. Hi, I've found some free time today and played with speakers. Before starting I want to mention, that my right front speakers are still not working at all since I probed accross #4 and #5 pins couple days ago. So, when right front speakers are not working and left front speakers are working fine, the voltage on driver's and passenger's side accross #4 and #5 pins are quite similar: ~12V when engine is not running and ~14V (little bit less ~13.xx) when it's running. But when left front speakers starts popping (working intermittently), the voltage on passenger's side varies usually between 9 and 11 volts. And I've got a wire and connected one end to the battery's negative terminal and other end to multimeter's black wire. Then I connected multimeter's red wire to #4 pin (red wire) and got the following results: On passenger's side ~11.89V And on driver's side ~12.44V Then I left temporary wire connected to battery's negative terminal and other end to multimeter's black wire and connected multimeter's red wire to #5 pin (black wire) and set multimeter to Ohms (200) and got the following results: On passenger's side ~2.0 Ohms And on driver's side ~1.8 Ohms Like I said before, my knowledge from college is rusty, so I'm not really sure what those measurements means..
  6. I probed accross #4 and #5 in D12 (see pic below) connector, which is above front amp and it showed from 7 to 11 volts (on avg. 9V) without engine running and very similar results with engine running (voltage never reached 12V or more). When I put connector back in place, front right side speaker didn't work anymore and only front left side was popping.. Not sure what happened and how could I break something, but hope that it's just temporary issue... Will try to find some time on weekend and will check driver's side speaker and let you know the results. Btw, thanks for taking time helping me!
  7. Yes, when it begins working, both sides begin working at the same time and stop working at the same time. I haven't used multimeter since college and my knowledge is a little bit rusty. When I was seeing "10", I was probing speaker wire connectors and multimeter was set on DC 200m, just like in the picture below.
  8. Ok, I bought a multimeter and checked the voltage. Strange thing happened, when I was playing with test lead tips on the speaker wires - out of nowhere they started working normally! I adjusted balance and fader and verified, that all front speakers were working! I put the speaker back to it's place with a smile in my face, then I increased the volume to 25 out of 35 and they stopped working again. They were randomly popping for a second just like it was before. Then I took out the speaker and played with multimeter again. And they started working until I increased the volume. When they were working, the multimeter showed 10 on avg. and 0 when not working. Any ideas what could be wrong?
  9. I randomly hear something for a second from one or another front speaker or tweeter. Sometimes I can listen for a couple songs without any sound from front at all, but sometimes it pops multiple times in one song. It's totally random as far as I can tell. If you take a look at my previously posted photo, I think, that the amp is that thing to the right of the speaker. I'll try to find some time tomorrow and buy voltmeter and get back to you with the results.
  10. Oh I didn't know, that rear amp only uses rear speakers. I'm 100% sure, that I have a bose system. I'm sure, that I quoted the right section (here's the link to the manual, look for EL-157). Today I removed front door trim and checked all wiring. Everything seems to be ok. So any ideas how to bypass this amp and connect the speaker directly to the head unit?
  11. Hi, I recently bought 2000 Pathfinder with Bose system and noticed, that front speakers doesn't work. They just sometimes randomly pop for a second and that's it. After doing some research, I took off rear amplifier and checked if all the wiring are not loose. They all were in place. Then I thought, that the problem may be in the factory head unit, because lights on it sometimes didn't work, sometimes work.. So I ordered the scosche wiring interface from crutchfield and installed aftermarket stereo. Rear speakers works great, but I can still hear popping sound from the front ones. Then I've found the manual and that's what it says: All front speakers are inoperative 1. Audio amp. relay - Check audio amp. relay. 2. Audio amp. relay ground - Check audio amp. relay ground (Terminal 3) 3. Amp. ON signal - Turn ignition switch ACC and audio unit ON. Verify battery positive voltage is present at terminal 1 of SC audio amp. relay. Could someone explain how to check audio amp. relay ground and what is the terminal 3? And how to check battery positive voltage presence? Do I need some tool for that? Or maybe I can bypass factory amplifier somehow and connect front speakers directly to my aftermarket head unit? Is it possible?
