I´m planning tp change the orginal HiFi System Professional DSP with new speakers and amplifiers.
Is that possible, i tried to search the board but my deutch is as bad as like Saddams breath

Have anyone done it? It´s a Alpina B12 5.7 Lang -98...and don´t worry, i won´t modify the interior.
Thanks in advance!
Kind Regards
Stephan
