Thread: help needed only rear speakers working

hi i wondred if anyone could help i have an aftermarket alpine double din in my audi s3 and have brought a pc9-401 cable but i can only hear the rear speakers is it possiblle to have both the front and rear speakers amped in the car and if so what lead would i need many thanks matt

If you have the Bose system then all speakers are separately amped so you need the PC9-410 (RCA input) or PC9-408 (speaker input).
Check the subwoofer in the boot, if it has two 4" drivers with a black front then you have the Bose system, if it has a single 6" driver with a metal front then it is non-Bose.

i definatlly have the bose system in my s3 but only have 2 rca outputs on my alpine double din so what lead is it that i need thanks matt

PC9-408
