Hi
Since a week i have a omega from 2001
it has a bose soundsystem.
I do not like the factory radio
Is it possible to remove it ?
I want to replace it with the alpine IVA D310 (dvd etc)

It won't be entirely straightforward.

You will need to:

remove Bose amp
replace Bose speakers (2ohm, unless new HU can properly drive these)
Loopback the speaker feed in the connector in rhs kick panel

is it not possible to use the amp on the alpine radio

[TheBoy]

you will need to use alpine amp, hence why you have to make changes above

[stef1981]

i do not like the factory radio
The alpine can play dvds ipod bluetooth handsfree.
i was hoping to put a iso adapter when i remove the factory radio so i just plug in the alpine

Nope, you can't without removing all the Bose stuff first, and adjusting the wiring to suit.  Trying to bodge the alpine in will likely end up damaging the alpine headunit due to impedence mismatching.

hmm
when you have a iso adapter the wires for the speaker will be the line in for the bose amp right?
is it not possible to place a converter between this?
does somebody have wiring diagrams for this system?

The bose does not work at line levels, it works at propietry levels, hence the problems.  Rather than mess around with trying to adapt these levels and fight impedence matching, just remove the bose stuff (and free up room in boot )

Also, be aware, there is not much room for various adapters behind the radio.

[stef1981]

Ok
i will remove the bose amp.
you say that the speakers are 2 ohm is this in the wiring?
so the front kickmid and tweeters are in series?

[TheBoy]

The speakers themselves are 2ohm.

Simple replacement is to find non bose omega speakers, which sound OK if used with decent HU.

There is still a bit of work around the bypassing of the bose.

Check this object should it not be the same system?

However to bypass the bose system i only have to change the connector on the rhs panel?

How well that would work on Omega Bose is unknown.  You will struggle to find room for that as well.

Constantly changing levels and impedence probably won't do much for the quality though.

I'd still go down the line of removing Bose stuff.

you will loose sound quality and its not a good to stick 4 inline FET's just to upconvert the 2ohm impedance to 4ohm! this can be done but not with a magic box of tricks!

as the boy said remove the bose speakers and amp and get a set of 4x non bose omega speakers and install the alpine with standard 4ohm omega speakers

you can sell your boss amp speakers and loom on ebay! for around £50 - £100 which should cover your speaker costs

you will loose the subs on the parcelshelf though! but 6x9s fit quite well!

[stef1981]

Ok thanks
too bad it could not work

[tmx]

bose units fairly good anyway i find!  loud enough for me!
