S/B Live Problem

**1Munkey** · 05-18-2006, 04:20 PM

I've finally gotten my project into my car and have a problem with my S/B live card that I'm not sure how to fix. Every problem I've encountered I've been able to fix due to

and so I find myself spending hours learning here

but unfortunately I can't find anyone with this problem....

I have my amps hooked to the "turnon" on my m2-atx and it works fine, but my S/B live does not turn on until after windows boots. Thus, I'm hearing a crazy amount of ground loop noise (I have an isolator running from the S/B live to the amps so it's gone once the card is on) and I get a nasty pop when the card kicks on. I guess the solution would be to rig the card to turn on with the amps. Is there a way to set the software to turn on at startup or a way to wire the S/B Live to kickon with the m2-atx "turnon"? How do people with external cards get around this?

It's amazing that no matter how cool it is once it's on, no one will forget that first 15 seconds of crap.

Thanks a bunch.

Oh I guess it's also customary to list what I have in it:

ASUS P4B
Pentium 1.4GHz
528 SDRAM
Maxtor 40GB
USB 2.0 Hub
Lilliput 7" w/touch
M2-ATX
DVD - slotload (not in yet, trying to figure out best way to hook it up)
Bluetooth Adapter - have it but need to see how ****ed off I'll get trying to get my Treo to work - since after numerous threads i've come to the conclusions it's probably not going to work

how about a delay on the amp turn on lead?

How would you go about creating a 15sec ish delay?

I wouldnt use a pulse timer in that situation, due to the fact that it's a temporary activation. I could explain how a DEI 528t pulse timer could be usefull in this situation, but i'd probably over complicate it.

There is a part PAC tr-7, that might be good because its totally programmable:
" Low voltage trigger. Gives you +12v output from headunits that do not have a remote output."

Thanks. I think my best bet may just be putting a kill switch on the turn on. That way I can kill it for the first few seconds and if I forget to turn it off they would kick off when I kill the engine. Also handy if I forget that I came home blasting the music and get halfway down the block at 7 in the morning when Snoop Dogg "Snoops upside my head"

at 120dB. Thanks for the input.

get the delay, you dont want to have to flip a switch everytime you get in the car...ANNOYING!!! i think you may be able to make a simple one with a cap and a resistor.
