Stereo, Subwoofer install
 

heya i need a lil help with my sub and amp install, ive done alot of these before but cannot find the speaker wires in the boot(trunk) area of my X

I have a Non DSP stereo and cannot find any Amp in the rear of the car

Will i have to pick up a speaker cable in the rear doors or is there a more convienent place??

thanks in advance

does any1 know what colour wire i should cut in to on my b pillar

i have found the harness to the door, just not sure which are the speaker wires

here...http://www.xoutpost.com/articles/x5/...ctory-amp.html

i havent got a factory amp, i have the business cd player

Every single X5 ever made has a amp. You need pics of location?

in my boot/trunk where the cd changer would be located is nothing, there are 3 plugs with nothing plugged in to them.

where else could the amp be?

It's on the left side, open that access door and it's down in the hole. It's mounted strait up and down. It's black in color.

theres nothing there, ive already had the car apart to fit the electrical wires for the amp

ill take some photos tomor and post so you can see

my x5 doesnt have an amp as its non dsp with no sub. I also want to fit a sub. Whats the easiet route to wire into speakers?

I have non DSP and no sub. But I did have a factory amp. It died so I replaced it witha aftermarket amp.

Maybe it's the UK thing... But here in US our X's came with amp.:nanana:

Well we in the US would tell you to tap into the wires at the amp plug. But if you have no amp....

Boonerp

i have a found a wiring diagram for the x, ill see if i can find the wires and if they work as soon as ive done it

I have Fitted my Sub to a NON amp/DSP X5

:popcorn:

To get a high level input you need to remove your B-Pillar
behind there at the bottem you will see all the wiring, you will see seperate wires wrapped in the black material.
remove a section of the black material from the smaller of the two bunches of wires and you should find 2 wires (in my case blue with violet strip and blue with grey strip, becasue i used the rear right speaker)

now you have you high level input for your amp, you need a remote on wire

Look in your boot/trunk and on the left where the amp is supposed to be you will see 3 connectors 1 will have a plug in in and the other 2 are left empty ( you may have more kit installed as factory option than me, but mine were empty)
the middle plug has a wire VIOLET with WHITE stripe -this is your remote on

the remote on wire only works on the ignition wire, and not when you just turn on the stereo when the igniton is off

i have a full set of cable identifcation if anyone needs it (only an id for speaker cables)

any questions post :trustme: here and will do best to answer

heres a pic of my b pillar and the wire i had to reveal to get the high level input

if you took the high level from the right side only, doesnt this mean you'd only have mono - ie you could miss part of the sound?

Congrats for sussing this though :)

......Sussing? What's that mean?

'sussing' means 'working' it out.

Apologies for our US readers :thumbup:

it will only be mono, im not really that bothered, its only doing bass and i CBA to take the passenger b pillar apart and run the extra wires

factory amp is actualy in the boot, you can take the high-lvel input from there, you don't need to remove b pillar upholstery.

Maybe not original condition
 

I was a car stereo installer for 12 years (in the U.S.) and have never seen a X5 w/o a factory amp behind the left rear quarter panel. In fact, just about every BMW I can think of since the mid '80s is outfitted with a head unit that supplies low-level outputs to an external amplifier. Possibly the previous owner of your X went through it and changed things up a bit. If you have sound coming from small dash speakers, and the car has not been modified, your X should have at least 6 speakers, and thus an external amp. I have not seen BMW use passive crossovers to separate frequencies.

Additionally, you are only using half of the stereo signal, so it is not even a "mono" situation except literally. Mono would be the sum of both stereo channels, and you are in fact only amplifying half of the total signal. I have fixed a lot of these scenarios, and believe me it makes an audible difference. You are not using your equipment to it's potential.

We are not in the us

Faranks, can you possibly help me out with this thread with your experience pls?

thx

every bmw has a factory amp from what i know. dsp and non-dsp.

check right next to the battery, under the plastic cover (which you should know is under the spare wheel). European non-dsp cars have the BM54 amp fixed there.

There are models (at least in Europe) that has reduced number of speakers (six I think) and no amp. Speakers are driven directly by head unit.

i am in uk as well they do have amps in the left below the plastic cover. i just fitted a sub and amp on mine and tapped into wires from the amp.
