    i need suggestions from people who have successfully installed the n66a from navone.

    Mine works half way, when i start the car the delay works fine and there are no pops, thuds, beep, whatever you wanna call em.

    BUT

    when i put the car on just the "acc" or "on" position the pop is there. Then if i start the car from there the delay kicks on and there isnt any audio for 20 secs. or so.

    Not sure why its doing that?

    Take a look at this thread:
    Turn-on amp POP Stoppers

    Pay attention to post #40 which is my idea utilizing an ELK-960 delay time from Smarthome. Cost is $23.

    Someone commented on 'what about turn-off thud'. Attached is my idea for the wiring diagram but what I just realized is I have it running off the ACC line. If I were to stop and get gas (for example) when I start my car back up, I would have to wait for the delay before the speakers would turn on. Perhaps running it off the +12V from the OPUS to the trigger port and the ACC line to the positive input. (I'll draw a new picture later.)

    EDIT: After looking at this wiring diagram a bit more, I realized that this may cause problems. If I turn off the car (to get gas for example) when I restart the car, I will have to wait for the delay again even if the OPUS keeps the computer on. It would be better to run 12V off the OPUS into the POSITIVE and use no trigger. (The ELK-960 is self-triggering on power up.)

    Those of you using the fake ups trick for a shutdown controller can just hook up a relay to one of the other control signal pins on the same serial port (search for fake ups shutdown controller). The amp comes on when only after the computer starts up... thus no thud. Works fine with hibernation too.

    what tells the navone n66-a to turn on the delay, i thought it was simply a small current from the turn on wire, but my delay only works if i start the car. It wont work when I put the car on acc. position. ANY EXPLAINATIONS???

    ill try using the 12v molex out of the opus and see if that will work for me, also when doing that will i have to use the black ground from the molex or can i sill use the car chassis ground or does it even matter?

    thanks

    How about a capacitor on the remote line in parallel? The cap will act as a short circuit so will charge first and then the voltage will be high enough for the amp to turn on ......bigger the cap bigger the delay ........price? $1

    it cant really be that simple can it? If it is then all 10 million posts about start up thud/pop/beeps need to be deleted and replaced with that one sentence.

    Any particular size cap to start out with?
