    Checked with autoleads today and they say that pc9 401 and pc9 404 both work with half amped B5.

    The only difference i can see is that one uses phono leads and the other uses speaker wire connections to power up rear speakers, am i right? Which would give the best sound or doesn't it matter? Cheers

    You'd get the best sound by not using either and just rewiring the rear speakers back to the HU. The shitty 20w Audi amp should really be bypassed in order to get the best out of the new HU, avoid alternator whine and provide the right balance front to rear.
