Well, I have tried to search the forums for a straight forward response to a question I have, but that was a epic fail so here I go:
My factory cd/radio has shat itself so I am going to replace it with a Sony MEXBT3900U head unit..
My tez has a live sound system, so I will need a bypass cable in order to bypassing the amp (apparently when you use it, the sound quality is shit??)
So, if I want to install this head unit, I just need to remove the old unit, get one of those fitting kits from TradeMe, get one of those bypass plugs then just plug everything up and its good to go?
I am a little confused about the whole thing, but I think all I need to do is plug the factory radio leads into the amp bypass cable then plug that into my new head unit??
1Do you have much aptitute in car radio systems
2Do you have a pre 2002 altezza?
Dont buy a bypass cable as it will end up destroying the internal amp on your headunit if your unlucky due to the low impedance of the read speakers.
I would classify myself as amateur with radio systems, I went to Mad Soundz in Hamilton which advised me to get a bypass cable and they would do me a deal and install it too, but I am trying to be cheap and DIY it lol
My Tez is 2001 and has the live sound system installed.
Ok well you have two options

they are expensive but effective but you will need to do this mod http://my.is/forums/f103/2001-metra-tyto-0...ess-how-338386/
The bypass cable will simply bypass your amp (obviously) and you will not get as good quality of sound. Your rear speakers may also sound out of phase as the impedance is wrong.
Hey I did the an install myself after HEAPS of research. basically i would recommend running a 4 channel amp and changing rear speakers. This sounds like a lot but if you actually look into some reviews of the metra harness you will come to find out that its not reliable.
I understand that you may want to keep everything stock and clean which was also what i tried to do. Bu take the time to think about it. Would you rather spend the extra $ with some quality sound or be only half satisfied.
My install included installing a new headunit, amping up my stock front and rear speakers. ( the rear stock ones sound so bad tbh, as tezz-winnie mentioned.) and a 4 channel amp.
PM me if any help is needed but im sure there are the pro's out there who know these cars inside out.
