hagar Posted May 16, 2006 Share Posted May 16, 2006 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?

l33r0y Posted May 16, 2006 Share Posted May 16, 2006 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 Quote Link to comment Share on other sites More sharing options...
hagar Posted May 17, 2006 Author Share Posted May 17, 2006 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 Posted May 17, 2006 Share Posted May 17, 2006 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. Quote Link to comment Share on other sites More sharing options...
Blacky Posted May 17, 2006 Share Posted May 17, 2006 yes you can just replace the head unit and it will make a big difference. Quote Link to comment Share on other sites More sharing options...
hagar Posted May 18, 2006 Author Share Posted May 18, 2006 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? Quote Link to comment Share on other sites More sharing options...
Traktion Posted May 18, 2006 Share Posted May 18, 2006 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!

Removed Posted May 18, 2006 Share Posted May 18, 2006 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 Quote Link to comment Share on other sites More sharing options...
steve_jones Posted May 18, 2006 Share Posted May 18, 2006 the bose speakers are 2ohm ( most aftermarket ones are 4 ohm), your Bose amp would not be able to drive 4ohm speakers .. Steve Quote Link to comment Share on other sites More sharing options...

Steve 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?

A new headunit will send a signal to the blose amp and that will drive the speakers. Quote Link to comment Share on other sites More sharing options...
Traktion Posted May 18, 2006 Share Posted May 18, 2006 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 Quote Link to comment Share on other sites More sharing options...
