Just wondered how you actually connect aftermarket speakers with the normal +/- tabs to the non-standard BMW connector?

Do you cut the wires then terminate with standard spade terminals etc...?
I'm specifically talking about door components for a 03 Sedan/Touring.

what kind of connections your new speaker have will determine what you need to do. no matter the type, you will have to chop off the stock connector (or splice) to connect new speakers.

BSW speakers are the only ones i know of that work directly with the stock tabs (i think).

you can use the wiring chart on the bottom of this thread to help ensure you have your +/- correct.

All aftermarket speakers have the same terminals / tabs. You connect using spade terminals but in the case of BMW connectors I assume that's what you do.

So of the 4-wire connector at the door speaker, 2 are just a kick-up to the tweeter?

Where is the crossover?

all aftermarket speakers do not have the same terminals, though most do have spade style connections. the ones i used (Infinity Kappa 60.9cs) did not have spade connections. and subs count as speakers too...

i had the non-hk system, and like all of the cars with amps in the trunk, it had dedicated wires going from the rear to each independent speaker. the crossover is integrated into the amplifier in most cars, though i'm not versed in cars from over the pond. your car either has an amp in the trunk (on the left side) with similar wiring or may be sending power from an internal amp in the head unit up front. in either case, i've not heard of any external crossovers being utilized by BMW.

hope that helps a little. maybe someone with a similar car will jump in here...

Kind of.

My main issue is:

'So if I cut the 4-wire connector at the door speaker, and 2 kick-up to the tweeter, won't I ruin signal to the tweeters? How do I do this without disturbing that?

Three options:

Destroy the original speakers and use the connections from them. (Requires soldering) etc

Use a splice electrical connector that cuts through the insulation and allows you to connect off the original. (Splice before the wire terminates with the connection block) Also called snap lock connectors see here:

Cut the wires and use spade or bullet connectors.

Mate. It is a massive no-no using those splice connectors - they are a terrible idea.

But again, my issue is a question of the crossover, not how to actually connect.

+1 I got so much effin static using stupid taps.

Gotta chop off the connector... and solder on new speaker wire w/spades. Always solder when you can... even though you're compromising the fact that you can't go back to 100% factory... you're going to end up with a crummy install otherwise.

I've installed the crossovers inline with no problem. I was told the crossover was built into the speaker, but looking at them I don't see how or where (looking at stock HK rear door tweet/mid). If the crossover is indeed in the amp, wouldn't the filtered frequency just get through the aftermarket crossover no problem?

the signal is filtered through the amp. i believe bmw uses an active x-over vs. a passive one. you should be able to connect the speakers without the x-over in place. unless you plan to run an aftermarket amp. you're not going to notice a huge (if at all) performance with just a replacement of the speakers anyhow.

Do the mid ranges (previously HK) on the front doors need a cross over then? My speakers for the rear door came with crossovers and I installed them and they sound fine. My front midrange 2.75" just came without crossovers and was wondering if they will work without them? Won't damage the speakers?

Still confused.

Can someone clarify on how the wires leave the stereo and reach the door speaker and then the tweeter on a standard non-amped, non HK set up?
I can only comment on the Euro E46 Vert with non HK and no amplifier.

It has an inline resistor connected to the cable/wiring from the bass/woofer speaker to the tweeter, see the circled area in the photo:



I cut and soldered spade connectors for my set up :



and shrink wrapped in the final install:



Then shrink wrapped the spade connections after fitting for good measure:



Obviously you cannot use the same / original tweeter cable with new tweeters if you want to use your own crossover because of the inline resistor.
(Unless you replace them with identical 8ohm tweeters - but then what was the point ?)

So in summary, the woofer / bass cable can be cut and soldered and the tweeter wire is best replaced. Any crossover needs to be wired in the door (or take a feed from before the amplifier - if / where the car has one)

Hope this helps, it shows where my crossover is in the door between the woofer and tweeter. I have a non HK and no factory amplifier set up. The speaker input feeds the crossover and the crossover has a tweeter output and a bass/woofer output which you connect to the corresponding speaker:

I'd say yes put the crossover in the door between the tweeter and bass as per my photo above, the crossover has two outputs one for the bass and one for the tweeter. Remember to remove the inline resistor on the tweeter cable if it is present in your car (see photo above) and solder connections for best results.

There's lots of videos on the web for how to wire a crossover - google is your friend
