when you say rear left door, you mean driver side or passenger? That is where you should be able to find the wires. Go back to the original page and look for the FRONT SUB wires as described, They should be there. |

my suggestion for an easier way to find the wires and make sure you are looking for the correct colors, remove the black trim piece that covers the driver's and passanger's front door rocker panels. it is the piece that makes the transition from carpet to out of the car. if you slide a plastic shim under the outside edge of the piece towards the front of the car, you can lift it high enough to get a flat blade screw driver under the panel. once the screw driver is under there, work it in till you think the end is at the middle of the piece and push down on the handle to pry it up. once the pop clip releases, work your way back towards the rear seats to get the rest of the clips to release.
once the piece is out of the car, find the seam in the carpet near the middle of the front seat. open it up and look under it to find the wires going to the factory sub enclosure to verify the wire colors you are looking for. If you find the factory amplifier in the trunk, these wire run back to that amp and will be coming out of it. all the wires described earlier in this thread will be bundled together, including the sub wires, and should be running along the drivers side of the trunk up and over the wheel well. if you found the ground block with all the brown wires, then the stereo harness should be right behind it. hope this helps |

in the lower left hand side of the 2nd pic you posted should be the stock amp. if you have logic 7 it will be silver. if you have the basic stereo system it should be black.
here is a picture of mine.

1,2 are one channel and 3,4 are the other channel. you should get a pac trunk-loc if you are gonna do this setup. if you use a pac trunk-loc: wire 1- (red/blue) will go with the gray wire from pac. wire 2- (brown/white) will go with the gray/black wire from pac. those are the right sub wires. wire 3- (red/white) will go with the white wire from pac. wire 4- (brown/yellow) will go with the white/black from pac. those are the left sub wires. green wire from pac should go on wire 4 (brown/yellow). ground wire form pac goes to ground on car or ground it to the amp(i grounded to the amp ground). red wire from pac goes to +12 on amp. blue wire from pac goes to remote on amp. good luck. if you need more help you can follow my link.

whats going on here? im pretty sure that bmw wouldnt have ran wiring for every cars that did want the logic 7 option. i would imagine the time consumption if it was. is it possible to locate these wires anywhere else because im definately stumped because i cannot see any black box or box for that matter in the location to where your silver logic 7 box is at.

i havn't removed anything since new.. its how i got it. it never came with any amps at all. hence the sticky situation of not being able to find the color wires described in this thread.

any suggestions to where else i could locate these cables from the front? if there is no more options i may have to really consider purchasing an aftermarket headunit just for a sub install.

today I opened the rear cover in my E91 and found the OEM amp and its cable connector. Here my question: why did you do tap into the wire from amp to speaker instead into the wire from radio to amp? That is the output of OEM amp for the subs and means loss of signal quality? Since I replaced the OEM subs with Audio-System subs unter the front seats I would connect these two subs with a 2-channel amp. Are there any possibilities not to cut down the 2 wires to speakers at the OEM amp connector, and just to rewire them some where else? I will be grateful for your helps. jonywalker Last edited by jonywalker; 10-25-2007 at 06:05 PM.. |

ok its been afew months since my last attempt to install subs into my car, i finally gave up and took my car to the professionals...... to find out they also couldnt install it hahahaha
i told them about how you guys have posted up pics with the standard amp etc, however it seems as though the australian cars dont have them. final verdict was for me to purchase an aftermarket headunit or a dvd system. i might have to consider this as my 'only' option.

did everyone use the pac trunk-loc?
ive been attempting to run it via an ordinary hi/lo convertor that doesnt have the low voltage trigger. the hi/lo that im using only has the speaker signal cables. will this be sufficient? has anyone achieved a working install with an ordinary hi/lo convertor? thanks!

I did worked fine for about 6 months but just smoked my stock amps back output. Don't know why everything was hooked up right, nothing shorted. The thing wasn't even used very hard. I'm sure that not going to be cheap to replace.

I just picked up my 2010 e90 335i, I've ripped the trunk apart and rear seats...can't find the amp anywhere! It's not on the left hand side where it used to be. I had a 2006 325i before this car and had no problem installing an aftermarket amp and speakers. Any suggestions?
