Hey Tho///a5,

Yeah, I'm still working to try to iron out the last kink...the dreaded alternator whine noise. I've tried everything I could think of and find online:

- made sure all unused plugs taped up with electrical tape
- toggled the "Brake" option in the Dynavin settings menu
- grounded the "Park" wire on the Fakra cable
- adjusted the gain down on the aftermarket amp (helps make it less obvious, but still there)
- pulled all the RCA cables (Streetwires twisted pair) from under the carpet floor and had it running straight through the interior cabin from the head unit to the amp
- installed a ground loop isolator (also helps make it less obvious, but still there)
- cut the amp ground cable to the bare minimum
- used a dremel to sand down the contact point where I bolted the amp ground cable to a medal piece of the suv
- ground the head unit's chassis
- tested with the shorter harness cable with the head unit in the trunk

None of it worked. Ultimately, I took it to a stereo shop and had them try to diagnose the alternator whine noise. They were able to trace it to the wires going into the Dynavin head unit (had to leave shortly after, plus did not want to pay for more of their hourly rate). I'm also in contact with Jeff from J&T Distributing and he's been really helpful (glad I purchased it from him). So at the moment, I'm waiting to get a power line filter delivered from Crutchfield in order to try it on the incoming wires into the head unit. In the meantime, I'm thinking of trying to run the red wire on the Fakra to the battery to see if there's any change.

Regarding the crossovers, I picked them up from eBay. I think they were like $20/each.
