dem shoes......
damm...sounds like my luck.....//content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
I 100% agree with everything said here. Talk to those guys and they will take care of you I am sure.Both Jacob and the guys at SoundSolutions are top notch people (bought my amps from SoundSolutions)...my original 100.4 had a bad channel...Jacob exchanged it with no problem...both amps working flawlessly now with no alternator whine whatsoever.
First thing I would look at is how the gains are set on your 100.4...I know mine was a lot more sensitive then the amp it replaced (did the same as you and just replaced the amp with all existing wires still in place) and I was getting a little whine...then properly set the 100.4 with an oscope (gain setting was different on the other amp...I never use the 1/2 way up scenario because it may not be the same from amp to amp) and everything was good after that.
Second I would contact SoundSolutions (Aaron was a pleasure to deal with) and tell them what's up with the 100.4 (assuming you still have the whine issue after checking EVERYTHING out before assuming its the amp) and I will almost guarantee they will help you with the matter.
Lastly I would contact Jacob (assuming that SoundSolutions won't help you...which I seriously doubt) and let hime know what's going on.
As far as the used amps having problems...contact Jacob on that and I'm sure he'll be willing to work something out with you...he's a real good guy if you treat him with the same respect you'd want (as are most of us).
Good luck and I hope you get those amps fixed....because Sundown is the real deal when it comes to a company.
Indeed... wish you were local so I could check it out myself.Oh hey, thanks for responding. Yeah it came back almost immediately. I didn't want to email you back because I believe you in that it sounds like a ground loop problem to me too. It's just hard to get the installers to believe me when they can unhook the 100.4 and hook any other amp in it's place without moving any wires and the whine stops. But then they put the 100.4 back and the whine is there. They're convinced it's the amp, and I have no way to prove it since I know jack about installing anything //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
If you swap 100.4 for 100.4 and it goes away I will exchange it for you. I do test each amp on my test bench with car batteries and a car head-unit so it's about as close as you can get to a car besides not having an alternator (which is a big factor in engine noise many times).What I could do, is deal with the whine for now and wait until DB-R sends me back the 100.4 I sent in for repair. If they swap out amps directly and the whine goes away would I be able to send the current 100.4 back for a swap? Or is that still not proof that it is the amp? I wish I knew more about electronics/wiring/installation //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
