  1. Since I don't have a SMD DD1 I went ahead and set the gains with the volume around 37 and used the multimeter voltage-match method. I seems to play pretty cleanly up to 37 or 38, nearly no audible distortion. Thanks to all for the input!
  2. I have not regrounded the head unit yet, but I never had any noise problem with the previous radio. The radio is grounded through the car's harness but I may try to ground it to the chassis and see what happens. I think I checked the resistance of the ground a while back and it read 0.00 ohms though. Big 3 might help but then again I wasn't having any issues prior to installing the new radio so I'm skeptical about the results (I know it would be piece of mind though, might do it eventually for the heck of it). I did readjust my gains when I installed the radio using the multimeter vo
  3. By ear I've been able to get closer to 38 or 39 but I'm sure if it were measured it would be closer to the 32. Thanks for the help!
  4. Hi, I recently installed a new AVIC 5100NEX and I immediately noticed the classic low-level engine/alternator whine coming through my front components (which was not present through my old radio). I had read about some Pioneer decks not having proper RCA grounding so I wrapped copper speaker wire around the barrels of the RCA outputs and then grounded that to the radio chassis. This seemed to take out the constant whine but there sometimes now is a very low intermittent static-type noise (thankfully barely noticeable unless you're sitting still and there's no music playing) and now it is
  5. Hi all, Was wondering if anyone has any verified experience (using an SMD DD1 or O-scope maybe) in finding the preout's clip/distortion volume level with an AVIC unit (5100NEX in this case). I'm not even sure what the max volume number is on the volume circuit but I know on the AVH line its generally around 39 or 40 but I think the AVIC uses a higher number scale? I know I can use the 3/4 volume rule of thumb but I was hoping to get a real account to better set gain. Thanks!
