replacing the bose head unit

[hagar]

now I know some people have thought about ripping out the entire bose solution and installing fresh.....

 

what I am wondering is this. If the bose system (thats the speakers) are powered from a bose amplifier and not the head unit itself, would it be possible to use a standard din unit with amp outputs and simply replace the head unit whilst retaining everything else?

The speakers and amp are the main reason for the poor sound quality.

 

The head unit is the main reason for the poor reliability.

 

Do yourself a favour and do the job properly

i am actually very very happy with the sound in the system, just the head unit looks a bit poor really - it looks about 20 years old

 

so keeping the speakers in there, is it possible to simply replace the head unit?

[l33r0y]

Hopefully, not tried it myself. Depends on the pre-out voltage in comparrison to standard heads. Hopefully someone can get a definative answer for you.

yes you can just replace the head unit and it will make a big difference.

[hagar]

seriously? So the Bose head unit can be replaced with any normal head unit that has standard amp outputs? Cool

 

what type of outputs are required and how many?

Interesting... I'd like to know more too! I'm about to get mine booked in to get the squeeky driver seat, no left channel on CD playing and a service

 

My warranty expires in November, so if my stereo keeps playing up or there is a better option, I'd like to hear about it!

don't the bose speakers work with low impedence or something? ie making it near on impossible to change the bose HU and have the speakers work? that's what i knew anyway

the bose speakers are 2ohm ( most aftermarket ones are 4 ohm), your Bose amp would not be able to drive 4ohm speakers ..

true Steve, but wasn't the actual question whether it was possible to LEAVE the Bose amp driving the 2Ohm Bose speakers and ONLY change the head unit?

 

Or have I got the wrong end of the stick?

i really need to have a ICE crashcourse

A new headunit will send a signal to the blose amp and that will drive the speakers.

I can't remember much about this, but ohm is measure of resistance, yes?

 

So, maybe if you use the wrong combination of kit, it'll either be more quiet than you expected or more loud?

 

Assuming the above is correct (it probably isn't lol), then a normal (4 ohm) head unit could drive the 2 ohm bose speakers, but you may need a bigger amp.

 

This could of course be total bollocks, but I hope there is someone who knows more about electricity than I do in here

 

EDIT: I just realised that this is a discussion about replacing the headset and re-using the same amp... I'll get my coat

You will either damage the headunit or destroy the speakers if you tried this , a normal HU is lookikng for a 4 ohm load on its outputs, if you half that it wont be happy, and even if it does work the speakers would be getting double their expected load and probably pop

 

As for just replacing the headunit, not sure to be honest, i think the weak part of the bose system is the speakers( there made of paper ) and amp!
