I bought mine last week and it is being ship as I type, I also am planning on redoing the system to bypass the DSP and hook up a 4 channel amp in its place (Alpine MRP-F300 AMPLIFIER 4 CHANNEL AMP). I ordered the sub box from Allstarsrd12 on this board and am planning on putting in an Alpine 500 Watt RMS Mono Car Amplifier with a shallow mount ALPINE SWS-1043D 10" 900W sub. I had already swapped out the speakers with Alpine Type-S SPS 600c, but the sound was still crap. chalked it up to the great X5 radio system.

Has anyone done a complete removal and reinstal of aftermarket components? want to know if there are any gotchas. I have read this thread inside and out and it seems most issues are with making sure the connections to the head unit are accurate. I ordered the new unit with the 40 pin connector so I will see how plug and play it realy is. I will keep you posted.
