factory premium stereo amp question for E30 cabriolet

[Jay Karolyi <karolyi74@xxxxxxxxx>]

Hi All,

Just remembered another problem I'm having.  I ran new wires for my 
component speakers up front, but want to use the factory wires for the rear 
speakers.  I replaced the factory speakers and matched up the colored wires 
at the head unit, but there's no sound coming out of them on either 
side.  I'm assuming there is a factory amp in the way somewhere.   I 
checked the archives and found out that the premium stereos had amps 
located behind the power antenna in the trunk, but mine doesn't.  (man is 
that carpet hard to remove!)  Any idea where they located the factory amp 
in the cabriolets or why my speakers aren't working?

In looking for the amp I found a weird box located in the right rear 
wheelwell where the battery is located in the non-convertible E30s.  What's 
in there?  It's a big, battery-size metal box with good size bolts keeping 
it shut (didn't want to explore).  A time capsule perhaps?

Sorry for all the questions, I just got the car and need to know all about 
it.  I'll stop being obnoxious soon I promise.  :)   Email me
