This tun software for control of JL dsp is pretty amazing. Lots of it is over my head but it helps to plan. Need to talk to my audio shop but the plan currently is.
step 1:
JL HD1200/1 for the subwoofer connected to the sub output of my upgraded double din.
step 2:
the above screen shot
double din outputs now go straight to JL VX800/8i
pre out L carries sub channel to the JL HD1200/1
4 bridged channels power 2 tweeters and 2 woofers in the door.
later on i'll add two midrange speakers, either unbridging 2 of the VX800/8i outputs to do it, or adding another 2channel VXI and a vxi hub.
probably overkill, have to ask the sound folks
speakers i'm looking at are JL w7 and c7 range.
