Upgrade The Roof Light To Led - Really Bright!

16 May 2012 - 11:24 AM

I just ordered this from dx.com:

I was tired of the dim light, the standard W5W bulb gave, so I got this - It's REALLY BRIGHT! Fit's perfectly in the W5W socket and holds itself in place.

I'm a little unsure which Ford models that does not have this type of roof light, but this should at least fit any Fiesta, Mondeo and Focus that does not come with maplights. Be sure to verify that it's a W5W socket - If it's not, I have seen other variations of similar LED boards on ebay with different socket types.

Frequency Response And The Need Of A Jl Cleansweep

13 November 2011 - 01:44 PM

I saw someone mentioning in these forums, that the best thing you can do for sound quality, is getting a JL Cleansweep device to flatten out the frequency response from the headunit. I was very curious about that and as the tech-nut I am , I wanted to see what the fuzz was all about.

Yesterday I replaced my factory default headunit to the Sony unit, and did measurements of both of them. My idea was that maybe it would not be nessesary to get a Cleansweep if you upgraded the unit. Here's what I found:

Green line is the factory unit, while the red is the Sony. Not much of a difference, so apparently they use the same DSP chip. I tested this using a CD with white noise and recording it to my laptop using a High level/Low level converter. The difference between the highest and lowest point is 10dB if you don't count the high rolloff (which you shouldn't because it's in the inaudible range).

So the Cleansweep can give you a flat response. It seems like a good idea, but I thought about it, and maybe there's a reason they add this DSP. Starting out with a flat response is a good starting point, but your room (and especially a car) would have an odd frequency response that you should correct using an EQ. The Cleansweep doesn't offer this ability. If they were smart, they actually supplied a microphone or at least an input for a microphone, so it could correct the DSP according to room response.

I might actually buy the Cleansweep and try to make some measurements. If I can get a good microphone, and get an analysis of the room response, I could apply the room response reversed to the pink noise signal calibration, they use, to fool it into correcting, not just the DSP but also the room frequency response.

There are some interesting Cleansweep demonstration videos on YouTube.

I hope this made sense :) I will update the post with my findings, if I get around to it.

How To Detach The Panel Underneath The Glovebox?

11 November 2011 - 12:27 AM

The panel underneath the glovebox is held in place by two nuts/dewels or whatever they are:

Can someone explain how I remove those? I searched but couldn't find anything, so sorry if this has been discussed elsewhere.

Tweeter Size

08 November 2011 - 10:15 PM

Have anyone measured the size of the factory tweeters? That's crucial information, when searching for a speaker upgrade for the MK7 :)

Slightly related: I've seen posts of people mentioning a 4+4-speaker setup. Are some Fiesta's fitted with tweeters in the back as well? If that's the case, are there any way to retrofit that?

Retrofitting Original Bluetooth Module, Questions

03 November 2011 - 08:05 PM

Recently, I bought a Fiesta Trend model (not sure if that's what they are named in UK). It comes with almost nothing - No A/C, only 2-line display, only speakers in front and no bluetooth.

I have got my hands on the Sony headunit and a bluetooth module from the same car.

Now I need to retrofit these. Some has said that it's an easy thing to replace the headunit, so let's hope that's the case.

Anyway, the bluetooth module, I'm a bit more curious about. It's a Novero RX-42 as far as I can tell.

Does anyone know if any wiring might already be done for this, or will I need to try to get a wiring harness from somewhere else? I know that I need an interior light with microphone and that there are probably no cable for this.

Does anyone know how I can get this wiring?
