    Hey guys, So i have a E90 with Logic 7, and of course it doesn't work. I have tried bypassing the MOST system with the loop thingy, but nothing seems to be working. Inside the amp I have two lights, red and yellow, and they are both flashing at the same time. I actually have tried putting...

    Soooo, I've had my e92 around 4 months now. No major issues just the usual DPF related hassle... so it's gone and I gained a load more power! :thumbup: However, I've been noticing that when playing music "too loud", the bass will completely cut out in the car for a few seconds before kicking...
