Compliments to VifferMike and Eias from Technic. I'm using both harnesses simultaneously. They work great without issues i.e. hum, hiss, etc. Setup with JL XD 600/6v2, the Focal IFBMW-S in the front doors (car equipped with Hi-Fi sys). Tried to install the Focal IFBMW-C on the rear deck but they don't fit, not even close. Awaiting a pair of JL C5 400cm's that should fit. I should have listened to VifferMike and gone with the JL cx 400 but i figured if i'm spending 5 bills on a great amp i might as well try and do better than a 140 dollar pair of speakers. These should sound marginally better. If i like them and can get them to fit i may add the matching tweeter JL (C5-075ct) and crossovers. I'll Eventually replace the Hi-Fi sys subs under the seats with the focal IFBMW-Subv2. When i installed the JL amp and the Technic harnesses and the dynamat in the trunk i installed the JL FIX 86 before the amp. After calibration of the FiX i lost the front tweeters. I checked all connections and recalibrated the JL FiX and still lost both front tweeters. I disconnected it and returned it. The only DSP unit i would consider is the Alpine PXA-H800 with it's included microphone. It's one of the only units that performs auto-calibration similar to what we've become accustomed to with home theater pre-pros and receivers. But it goes for $700 and that's too much.
