So I’m new here and I figured I should start off by contributing. I’ve seen lots of threads on stereo installs and I thought I’d share my experience and the things I learned while doing this. I replaced the factory Bose head unit in my 2001 Qx4 along with both sets of door speakers as well as adding a blaupunkt integrally powered sub. I decided not to run all new wiring since reading through other threads people have seemed to be frustrated by trying to get it through the door grommets. For the head unit....I used a scoche wiring harness for the head unit and all the colors matched up just fine.

For the dash kit....I used an asc which said it was for a 2001 pathfinder or qx4, however, it is not an exact fit. There is a large gap along both sides and on the bottom. I have a metra dash kit on the way that will fit. I should have checked this first but you know what they say about hind sight.

Next up for the front door speakers. What I did was remove the guts from the factory amps....but I left the shells on the door so I wouldn’t need new bezels to mount the speakers. I took the wires going into the amp, and attached speaker connectors to them and connected the speakers and wired them in.

For the rear speakers this took a little figuring out how to do with the factory wiring. I started by removing the amp and cutting off the wiring harness. I then jumped the wires going into the amp with the ones headed to the door speakers. Here’s the colors for those so you know what to connect.

Left speaker: connect pink wire to green for positive. Blue wire to black and green for negative.
Right speaker: connect light green and orange for positive. Connect violet and black/pink for negative.
When you get to the speakers, orange is positive wire and black/pink is negative

The sub I used is an 300 watt amp/sub combo from blaupunkt. Not super loud, but plenty of bass for what I wanted. To power it....I used the green/white wire for 12v power. Black for ground. And I ran the remote from the head unit as well as rca cables. I ran the sub control knob under the carpet from the rear up to the arm rest console and mounted the knob inside.

Pretty happy with how it turned out. It was a pain and took me two days all told to figure out all the wires and everything. But it’s all buttoned up and sounds great now. Hopefully this could help someone else who wants to upgrade....but doesn’t want to have to run all new wires to everything in order to bypass the crappy Bose factory amps.

I ordered it from walmart online for 49.99 plus free shipping, but yes this is the sub. It takes up very little room and sounds pretty good. If youre looking to set off peoples car alarms this isnt the sub for you. But if you just want some decent lows this does the trick

It's $84 now. Were you able to get it to fit under the seat? Passenger seat?

You probably could if you didnt have the electronic adjustable seats....but with the motor under there it wont fit. I mounted it to the back of the bench seat on the drivers side and its working out just fine

Can someone help me out with which color wires I need to use for the front door speakers? I installed a HU and new components but don't know which wires to use. I also need to wire the tweeters in.
