Would it help if I wrote a quick guide to BOSE to add to the FAQ pages, a bit like the CDR ones I did a while ago?

 

I've done a quick and dirty sticky in this section, feel free to suggest additions/corrections

How do I get around the 6000 character limit then?

dave you seem to know about this subject quiet well, i have my parrot bluetooth car kit to go in my miggie with said bose system, this cuts the sound from stereo and puts the call through car speakers, is this safe considering what im reading on here    adey

[Dave DND]

You may struggle a little with the Parrott kit, as it may not initially work too well with the BOSE.

However, I am aware that there is a little mod that can be done to alter / balance the output of the parrott to work with the BOSE, but I`m afraid that I do not have the specific details of what needs to be done.

Buut don`t worry, I know that there are a few Oofers that have already done this and got it to work quite well, so I would suggest to start a new thread about Parrott and BOSE just in case those in the know overlook it on this thread

Although you can feed the speaker output of a headunit with BTL output into the Bose amp if you can do the resistor calcs.

Hi all
just thought ill come in and give my info on this one

first of all if you got a bose system fitted in your car
and you want to just change the headunit, its actually not that difficult.
all you have to do is use the line out on your new aftermarket headunit and connect these to the existing wiring loom on the speaker outs.
to make this simple. youll notice the speaker wires that connect to the headunit have a black sleeve around them, there should be four of these, one four each channel. cut these wires and connect male phono plugs on to these, this will allow you to plug these phonos stright into the back of your new hedunit.
thats it job done
you will lose the diplay and steering controls but thats life.
i had an alpine headunit with 4v preout connected like this and it ran smoothley without any issues

your other option is to chnage the amp ( i would recomend this) as i think the bose amp is shite , not powerful enough,
ive got 2 here if anybody wants them

using the same method as above,use the existing wiring, and convert them into phonos, you can install a new amp in the back
this will make a world of a difference
alot of new amps can run at 2ohms so no issues there
all you need to do is upgrade the power line and give the new amp a better ground


sorry if i havnt been able to expalin it properly but i see your in the midlands
im in birminghma near the swan if you want to pop around i can show you my setup and advise you better

tango - I wouldn't recommend anyone uses an aftermarket HU with a Bose amp. Replace amp (and speakers!!) at same time. ie, rip the lot out

[tango]

ive heard many people say that but ive been using one for a couple of years without any issues
so i dont see why not
what is that makes you not recomend it
its an amp, its got inputs and outputs
and conveniently it has four inputs, so all four channels can be used seperatly

That is precisely why, things are not that simple.

For starters, the Bose amp expects a non-standard voltage level for its inputs.  It also appears to have a non-standard response curve.  Not measured myself, but lead to believe its impedence is non-standard as well.


To take you analogy further, but keeping with bose, a speaker is a speaker, surely? Its got 2 wires, and makes a noise?  But plug a bose speaker into a chav headunit will tune said headunit to channel smoke, due to impedence issues.


Its a simple thing with Omega Bose. Very simple. Either use it in its entirity, or remove it all, entirely . No halfway house

The Bose wiring makes it dead easy to fit a modest amp in place of the Bose amp. Modest amp, mind, as the power feeds aren't suitable for "look at me, I'm a chav" type amps.

whats a non standard curve
and if you havnt tested how can you be so sure
ive tested and used for a couple of years, im a taxi driver, so my speakers get hammered 8 hours a day
this is without issues
the bose amp is no different from a standard amp
other than its inputs are fixed so not variable


and i reckon the only difference betwenn a bose unit and a standard unit is that the bose unit has its internal amplifier disabled, so speaker outs are turned into pre outs
i havnt measured them but i reckon they must be around 2 volt thats pretty much the same as other aftermarket headunits
but i had alpine unit with 4v preout doing a fantastic job
and ive already mentioned that to change the amp you can use the same wiring all you need to do is upgrade the power and ground cables

All audio devices expect certain characteristics with varying audio inputs. These are response curves. For example, a vinyl record deck needs a preamp with a RIAA response curve.

I haven't measure the impendence of the amp, other bits I have

And to the last comment about the bose amp being no different...

//Panto mode on
Oh yes it is!

[tango]

i think we gonna go round in circles

if your local pop around ill show you my setup
ive got it working in my car and thats proof

If ever you're any where near Paington you'll have to call in on DaveDND & show him where he's been going wrong all these years. 

[Kevin Wood]

Any modern aftermarket amp that can truly drive 2 ohm speaker loads will deliver enough power into 2 ohms that they will set fire to the cardboard Bose speakers in short order.

Why, oh, why would you invest in a (presumably, decent) head unit and amp and not replace those nasty speakers?

Best just to leave it be or replace the whole system.

[Marks DTM Calib]

The input to the Bose is a standard flat response for info.

Slightly surprised that a standard RCA out worked as the Bose does expect a slightly odd voltage balanced input.

At the end of the day, its only pretty basic audio stuff

[feeutfo]

Is it fair to say, that the best head unit/system for the omega is the standard one?(within the realms of 2011/13/15 etc or whatever)
And that ANY alteration from the complete system will also have a down side, such as loss of basic functions, like check control, bc, or what ever...?

Theres no doubting technology has moved on since the design stage, but that same technology and the ice industry generally has yet to find a way to improve on the system as a whole, without loosing at least part of the functionality. Ie, there are better/newer systems, but none have a remote dash monted display that work in omega, for example.

In short, if there is a system for omega that works better than standard with out loosing functions, then nobody on here knows about it. And no cd70 doesnt count....yet. Apparently.

If there is, then bring it on....
