Upgrading the door speakers

[seikokid]

Just found a copy of the wiring colour code , it mentions only that there are 2 front speaker and 2 rear speaker wires. I really would like to find the cable points were the tweeters and doors speakers join

Probably close to the A pillar, it doesn't matter though as the signal is exactly the same. It might be a good place to mount the x-over though.

Fitting the crossover would have to be before the point where the cables are spliced and go off to the tweeter and the door speaker

I have looked into this - being an electrician myself I can see how it's not an easy job to fit these crossovers , in that this is a 1 year old vehicle and to start cutting up the loom is not what I really wish to do and there's quite a tight bunch under that dash . I'm not that fussed about the "perfect sound " because already fitting these speakers is far better than what I had and that was ok for me , just my hands free had started to wear out the tweeters . So I had a chat with my electronics repair guy and also some helpfull guys down at one of londons big car audio centres , if I fit a 4.7uf or similar Cap Across the new tweeters I will be back to my original set up just with new speakers . Until I can find a loom splitting kit or something neat and professional I'll use this method for now

You can get a T-Harness for behind the stereo if you don't want to be cutting the loom.

I fitted my X-overs behind the glovebox on the wires going to the mids and ran new wires to the tweeters - job done

please can you expand on this T Harness , do you have a link I can look at please ?

it would be good if both the left and right speaker cables go behind the glove box, more so the right side to allow both crossovers to be fitted in the same place

Have a look at this:

With this you can chop into that, extend the wires down to the passenger footwell for connection to the crossovers, then run new wires to the tweeters

Perfect , that will do nicely !

Job Done ! thanks for your help

So I'm at a loose end !?! - Tuning box removed and engine whine noise coming through tweeters when reving and driving. It's in tune with the engine so goes up and down with the revs . With the power disconnected from the inline amp I still get it from 1 tweeter and both when connected.
have upgraded door speakers to a set of focals.
Amp negative is spliced and grounded to chassis

Any ideas on how to eliminate the noise please ?

[seikokid]

Would appear the noise is generated by induction through the crossovers / loom wiring.
The ISO cable would need to be totally run as separate power and signal cables, but without cutting and remaking / extending the entire loom I have to put up with other options. As of now I've moved the crossovers to under the passenger seat which brings the feedback to a bearable minimum but doesn't quench it completely.
Several chats with auto electricians have informed me that the custom is renown for this issue .

That Italian fella that was here had the same problem, I told him a few times before he decided to move the x-overs (solved his problem). The ISO cable doesn't pick up any noise IME and I had zero noise with the x-overs in the position that you now have them.

I would't say that the Custom is 'renowned' for this or even as bad as the MK7, but poorly shielded x-overs and amps will always pick up stray noise, especially if poorly placed. The other source of noise is the amp gains being too high.

I hear you Mike , thing is before I bought the focals I had the in line amp as my first upgrade and this was when the engine feedback started - albeit not that loud I couldn't decipher if it was the tuning box or the amp - being lazy and always at work I never tried to disconnect the items and sample the differences ( plus my amp was behind the dash )
but I have a new van now and a remap. I also repositioned the amp under the steering column and installed the crossovers.
the noise has always been worse when de accelerating
I was advised to wrap the crossovers in lead flashing by a top end car audio company in Park Royal ?!?

[Mike]

IMO there's just too much electrical equipment in the dash area, which is why I mounted all my audio stuff under the passenger seat. Wrapping it in lead is unlikely to work unless you use shielded speaker cables, unshielded cables will allow interference along them and into the x-overs even if they're encased in lead.

[seikokid]

Sooooo!
Ripped everything out , bought a new Alpine amp and a wiring kit and fitted it as follows , and would you believe it I still get the whining !!!

Main power feed taken direct from secondary battery



Speaker cables spliced , soldered and heat shrinked


Amp mounted on bulkhead under passenger seat


Speaker wires run under carpet to centre of dash then up to head unit


Crossovers mounted under passenger seat on outside panel

Anyone got experience in these products (speakers and woofer)

I will probably get a free upgrade from the dealer and getting these speakers from ford is by far the easiest way if it's free.

Should I look for something else or is it a reasonably good upgrade?
