Wiring Diagram

icetuto · 02-05-2019, 11:30 AM

Hi my friends, i have a e92 without amplifier in the back, im trying to install a amplifier and a subwoofer. i have some wires near the battery on the right side, are those the wires for the speakers? if they are which ones are for the back speakers?
i need power from the speaker to connect a high pass converter to convert to rca. i tried to find diagrams online and here but no luck

ps: i dont want to run wires from the doors because its a pain in the a** and i dont want to have so much cables running around the car.

thank you in advance!

my e92 is not a lci but it was produced in 01/2010, so if i try to do like my f20, and connect to the subwoofer underneath the seats am i going to get some actual bass?

i dont need anything like.... WOW you know, i just want a little bit more bass

Base system is a POS . It will never be able to keep up
with a subwoofer. But maybe that is all you want don't know.
The Hi Fi system is not that much better.
The underseats and the doors share the same signal so that
would be the place to hang your Loc off of.

I drove and X2 the other day with a Hi Fi system they don't even
bother to put tweeters in it anymore very unimpressed.
You could only turn it up to half volume before it started to distort.

If it was me I would do something similar to the upgrades I listed.

You have to understand that BMW makes three basic systems and none
of them are very good .

very weak as i can see... btw i noticed one thing, when i go up 160km/h the bass keeps distorting you know why this happens? i just ear it from the passanger side, i have the "speed music volume" or something like that all the way down. Even if i turn down the volume this happens

I am surprised there is any bass at all at any speed.
I think you would have to inspect the speaker.
But the system probably starts to distort at half volume,
so it there any point to this.

my f20 has a worst quality than the e92

it only happens at high speeds so it shouldnt be a blown speaker

Speaker loose debri in or on speaker.
Visual inspection or maybe you need new shocks.

Stereo's only came wired for the type of system you got with the car new. That means if you got the ampless base system no stereo wiring extending to the trunk and if there was any it would be on the side opposite the battery side if you had the 676 or 677 option. (Hi Fi or logic 7) http://www.e90post.com/forums/attach...5&d=1493273253 There is a company that makes Wiring Harnesses for aftermarket stereo in these. Also you should be aware that the underseats speakers and the front door speakers are wired in parallel in the base system and the connection is made either in the door sills for early model cars or at the under seat speaker connectors for later model cars. https://technicpnp.com/ Base System Upgrades http://www.e90post.com/forums/showthread.php?t=445266 http://www.1addicts.com/forums/showthread.php?t=634957 http://f30.bimmerpost.com/forums/sho....php?t=1003810 http://www.e90post.com/forums/showthread.php?t=822366 http://www.e90post.com/forums/showthread.php?t=581379 http://www.e90post.com/forums/showthread.php?t=451941 http://www.e90post.com/forums/showthread.php?t=540954 http://www.e90post.com/forums/showth...ghlight=Dotech http://www.e90post.com/forums/showthread.php?t=495855 http://www.e90post.com/forums/showthread.php?t=494299 http://www.diymobileaudio.com/forum/...morel-jbl.html http://www.e90post.com/forums/showth...ht=amp+upgrade http://www.bimmerfest.com/forums/sho...d.php?t=550771 http://www.e90post.com/forums/showth...1#post16679904 http://www.e90post.com/forums/attach...1&d=1411521234 http://www.e90post.com/forums/showthread.php?t=1378833 base system wiring pre/post 3/09 http://www.e90post.com/forums/attach...1&d=1411521234 https://www.google.com/url?sa=t&rct=...tDpLJPcGkw_ui_ http://www.monsteraudiodesign.co.uk/ http://www.e90post.com/forums/showth...1#post16679904 BMW stereo types http://www.e90post.com/forums/showthread.php?t=352586 http://www.e90post.com/forums/attach...2&d=1266451970 http://www.e90post.com/forums/attach...2&d=1260829447 http://www.e90post.com/forums/showthread.php?t=343673 http://www.e90post.com/forums/showthread.php?t=138949 http://www.e90post.com/forums/attach...1&d=1209780605 http://www.e90post.com/forums/attach...1&d=1209780865 http://www.e90post.com/forums/showthread.php?t=641323 http://bmwcoders.com/forum/3-er-8/bm...1-e92-e93-291/ http://technicpnp.com/menuDiagrams/d...e90_92_93.html http://www.musicarnw.com/page-2/ http://www.e90post.com/forums/attach...3&d=1169133185 http://www.e90post.com/forums/attach...4&d=1278871872 Last edited by ctuna; 02-05-2019 at 12:19 PM..
