new head unit wont work with bose speakers, anyone help plz?

[gyles18]

alright guys, bought a new jvc dab head unit last night for the rex because the standard bose stuff pritty much gave up. anyway head unit works fine, powers up, plays cds etc.......but one major problem......doesnt have any sound. now i know the bose stuff, which is already in the car, runs an amp of some sort in the back. spoke to a mate of mine and he said best option is to re-wire the speakers. the bose system doesnt sound to bad but the main reason for keeping it all is because i want to keep the car as standard as much as i can.
anyone else had the same problem, if so what did they do.
plz help :confused: :2Confused
oh and i know this could be a bit impossible, but by any chance in the world, does someone have a wiring diagram for one of these?

sorry, forgot to say i have the mazda iso plugs which you need to connect the new headunit up.

I had this exact same problem when i changed my head unit.  As i recall you need to put a live feed to the green/black which is a feed to the amp in the rear of the car....

worked out how to do it.
for anyone else who has loooked at the feed and has the same problem, what you have to do is join the green and black wire from the mazda side of the wiring with blue wire from the iso plug. pritty simple. just took me from 6 last night till 11 this morning to work out!
