Well the rain is starting to come so then I lose interest in the car! Well not quire, I went with a JBL mono channel 200 W amp in the end. I've been spoilt with the e63 sound system so just wanted to be able to get a small bit of bass & be able to turn down the bass output from the mid range speakers in the car. So hopefully I'll be able to listen to the radio a little louder now without distortion when I've the roof down.
