2001 Audi A6 how to bypass the original amp

Hi there,

The stock amp (mounted inside the sub enclosure) found on the RHS of the boot behind the pull out pannel has a red plug with 8 twisted pairs of wires and 3 other wires (pos, acc and earth).

Out of the twisted pairs you will have

RHS Rear Speaker: Blue/Gray +, Gray/Blue -
LHS Rear Speaker: Red/Gray +, Gray/Red -

You will also have a pair of White/Blue and Brown/White which is the RHS input and a White/Red Brown/White pair for the LHS input. Although... the stock amp uses a common earth input as you will see, the two Brown/White wires going into the same plug.

To put in another amp, you will need one with 'high level' input. Make sure it can take a common ground type input. If it cannot then just use a "high level to RCA" converter.

If you are putting in an after market headunit like i did, then you will just need to separate the two brown/white wires at both ends. If you do this you will need to test which brown/white wire at the head unit end is paired with which wire at the amp end. They are twisted together at the amp end but not at the headunit end (unless you cut the cloth tape back far enough).
