I don't believe the factory sound system has RCA level outputs. Basically, your two options would be:
a) run an aftermarket amp that has high-level (speaker-level) inputs
b) run a line-out converter (loc)

Here's the wiring diagram:
REMOTE: white/violet stripe
LEFT LINE-LEVEL NEGATIVE (-) black/violet stripe postive(+) black/red stripe
RIGHT LINE-LEVEL NEGATIVE (-) black/brown stripe postive(+) black/white stripe
LEFT SPEAKER-LEVEL OUTPUT from amp: negative(-) red/white stripe postive(+) brown/yellow stripe
RIGHT SPEAKER-LEVEL OUTPUT from amp: negative(-) red/blue stripe postive(+) brown/white stripe
POWER: big red wire
GROUND: big brown wire

Hope this helps.

Right in your post is says line level. Now i am confused. does the head unit send a line level signal to the amp in the trunk or not?

Thank you for the help though.

To be clear, is this the wiring info for a Logic7 equipped E60? I hate surprises when I'm trying to do an install.

i have subs in my 530i....two 12's (polk audio) with a kicker amp with dynomat in the car
love to hear the system no problems...yet
only problem was rattling but i got it dynomatted and its a lot better

Im getting a full system redone a dash redone
im sealing off a Hertz HX300D in a sealed box custom and angled to fit the ski pass i will force feed all the base to the cabin 1000k using an Alpine MD1000
running CDT competition ES7 7" midbass, 4" and 2" tweeters on kickpannels wich are done already.

Using Alpine Vhub, Alpine PXA h701 processor , and Alpine TME 740BT touchscreen all fiberglassed in to the console.
Alpine F1 Status amplifier to run the comps and Helix HX 400 to run the midbass on the doors.

also installing Alpine DVA 5210 DVD which will be installed in the glove box for videos, cd etc. Alpine Balckbird navigation feeding in to the touchscreen
and a fully integrated Bluetooth so that i can receive and make calls going through the stereo system speakers.

i have tried different shops and all of them have screwed up the system, i have someone that has built demo cars putting this baby together. Once its done i will post pics.

Its not easy with so many components but i think the SQ on this system will be unreal.

Lexus has gone above and beyond expectations with their Mark Levingston system, it is incredible, all it lacks is bass which coudl be fixed with the right sub and perhaps an ingeration processor.

BMW stereo sound still has a long way to go even the Logic 7 i think its horrible for a high performance vehicle. I beleive the price tag on the Logic 7 is incredible. for such poor quality sound.

Yep, Logic 7 in the LCI is not great. But if you are in an area that allows for the "BMW Individual Stereo", well, that's just in a different league - absolutely awesome, certainly the best factory fit stereo I've ever owned, and I've owned a lot of cars!

dont forget dynamat! you will need it with all that bass

rjcastr

I already dynamated my trunk but it wont rattle the design is for the bass to push force through the ski pass no bass will cancel in to the trunk Im not blasting it to full 1k watts im building an SQ system therefore it will focus on sound quality.

I whole hartedly agree. The HK stereo on my old 89 range rover with a fosgate amp sounded better then this L7 stuff. Maybe its cause i had better hearing back then too. LOL
