Amp is in and working. The EQ is way off. I need to get someone local to tune it.
Updated: I used EQ settings from the 7 series forum. It sounds better but I think someone local needs to sit down and tune the E90 for the new amp. Before the summer time I will need to wire in an amp fan. I am going to use the CD changer pre-wire power cables for the fan.
