Hi!
I've just installed an aftermarket stereo in my 98 A4. 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 *am* supplying 12v to the rear amps - if I disconnect the 12v then I get no rear output at all.
Anyone seen this? Is there some sort of control on the back speakers where I can turn them up?
Cheers! James
