[Tjoppies]

i cant seem to find proper explanation on what speakers i have , if i have a sub/amp , speaker sizes, output etc.

i dont have the HK system

looking for a mild upgrade , no sub boxes in the trunk - has anybody done a speaker upgrade?

When I bought my E46 it had an AMP in the boot with Rockford Fosgate mids in the standard locations. I added an under seat (Front Passenger) Fosgate Sub and the upgrade was amazing - I just wanted a bit more bass with clarity.
