Rear speaker problem with after market head unit

allaire_99 · 08-05-2008, 08:58 PM

Hi!

I've just installed an aftermarket NAV (pioneer AVIC F90BT) in my 2005 A4 and The rear speakers are VERY quiet compared to the front speakers, which means they are pretty useless unless I fade right back and increase the
volume.

The rear speakers are of course being fed by RCA preouts on my head
unit, and the front are connected as normal via the iso block.

I connected the amp control signal (Symphony II pin #6 in line out slot) to the remote amp on audio harness of pioneer.

Anyone seen this? Is there some sort of control on the back speakers
where I can turn them up? Am I missing something in my connections?

Cheers!

i have now fitted a sub and amp in the boot, so i am going to wire them into that unless someone comes up with a solution soon
