Hi, can someone plese help me understand this. My setup in e60 is standard 6 speakers setup which I upgraded by adding coaxials in the front door, alpine tweeters and the tweeter enclosure, sws8 underseats and stock rear all driven by PDX5 in the boot. Coded n CIC on hifi so I am getting all 4 full range signals low level straights into PDX. Now if I want to add H660 which line should I connect input and output too? What shall I keep my PDX 5 cut-off freq for each channel?
Please someone guide me I am doing it this weekend, fingers crossed.
