Alpine 505 Mra-350 and MRA-M500 Settings

Hey All,

Finally got the install done yesterday on the truck. I have a x-over question. I am wondering where to set the crossover on the sub amp to start to tune it. The hu/mra-350 have the hp and lp for the sub built in to it. I am wondering if I turn the setting on the MRA-M500 all the way up or down to bypass it. I cannot find any literature from alpine.

2nd - the fronts have there own x-over in the system so wondering if I should run flat to the fronts.

It is sounding pretty good. I have to do time correction this morning. I have the fronts (I reference components) rear and center set to pass at 100Hz flat right now, still playing with the slopes 12db seem pretty nice 24 is really harsh. I have the center width set to 5 for PL-II and the tweeters for the fronts are in the a-pillars of the silverado and cut to 0 db They are still pretty bright bouncing of the windshield. I have the PXA-701 installed in the truck but not hooked up and that may be the way I go if I could find a good amp for equal 6 channel output.

The WALL live in berlin sounded pretty awesome in DTS last night though.
