Turn-on amp POP Stoppers

Gene · 06-28-2004, 06:14 PM

After doing a

on how to eliminate two pops from my speakers when I turn my car on, I came across two products:
Stinger's http://www.sfxaudio.com/products/dis...p?ProdId=63361
and David Navone http://www.davidnavone.com/detail.asp?PRODUCT_ID=N-66A
Do you know any other solutions, what are you using?
I have one 4ch amp / 4 speakers. Do I need to get only one item or two (one for each RCA cable)?
Thanks

I have the david navone and it works quite well

Gene i believe that you need one per device that causes the popping noise.

you only need one...it goes in between the remote wire going to your amp

errrm i just use a standard switching relay...

ignition wire goes through relay to the remote of amp, and is switched by the computers +12v.. that way it dosent power up till after the sound card has started, and powers down when the ignition does.

mutilator,
I don't know anything about relays, which one would you recomend: SPST or DPDT

Gene you would only need a spst for your amp. How it works it, there is a coil inside and when a voltage goes through the coil, it creates an electromagnet which pulls a little switch inside of the relay. You would run the power from the carputer through the coil and the remote line hooks to the internal switch pins.

Some amps have a turn on delay that might be a good solution for some, but my system is personally run with the relay technique. Works great.

I'm going to try the relay first. Where does the remote wire go from the relay? Do I need to tap in into existing remote wire going to the amp from ACC? I must be doing something wrong, everything comes on that way but the two pops are still there. Am I way off on this one? Or, do I go from ACC to the relay and then to the amp (haven't tried this one yet) Here is my setup

the acc line does not go to the amp anymore, you will use the 12V from the relay to trigger the amp.

OK, so the ACC that used to go to the amp now goes to the relay. Thanks

You wouldn't need the ACC line going to the relay would you? Can't you just run +12V from the power supply right to the amp's ACC lead? Or does the time it takes the relay to switch make a difference?
