RAY HELP! 06 BMW 750 Li amplifier install


Recommended Posts

I ca't find any wiring diagrams anywhere. Stock stereo.

I am helping a friend install an amp for a sub. He had a friend of his attempt to install it with no success (he actually fucked things up in the back, i would kill him if it were my car).

My main 2 questions are....

What should i wire the amp turn on button to? Or should I run a relay?

Without running a sound processor, is my only other option to run a line out converter for the signal?

I cant find anything online concerning an install in this car.

Any help is appreciated from someone who actually knows what they're talking about.

IMO the stereo sounds great stock with the factory subs but it's his car, not mine.

Thanks brahs

Thanks Ray, you the man!

Chief....I was hoping to find signal in the trunk where the amp is to save time and wiring, however it's a very crammed space up in that left corner!

In a pinch or if hes cheap

The 12awg twisted pairs off of the factory amp are the 8's under the front seats.

Can hi-low there, and grab 18awg white for amp turn on.
