sub and amp on stock headunit

[=Calais v8=]

so when the amp its plugged into a headunit using the RCA leads, the power is cut when the headunit is turned off?

if the power cable is run straight from the amp to the battery, and the earth is always connected, that would be a complete circuit which means it would always have power. how does the power get shut off on yours?????


EDIT: i noticed my amp has the + terminal, the GND, but also has a "power control wire". im assuming this is what causes the amp to turn off? do i splice this wire with say... the stock headunit power source? will this work? or will i blow stuff up. thanks for the help

an amp will have a "remote" wire terminal or "power control wire" as you said, basically like a relay setup. when 12v passes through this wire it tells the amp to 'turn on'. an aftermarket head unit will have an external remote wire for you to connect this to so the amp will turn on when the head unit is on.

so i can simply splice this into the radio power source to have the same effect?

what? the remote wire? to make this a bit easier, what are your decisions? are you going to go with a new head unit or stay with the original and use signal converters?

the 'power control wire" (i want the amp to turn on when the stock headunit is on). i am sticking to my original.

ok with the 'power control wire' or 'remote wire' (same thing), you can splice this into any 12v accessories source (that gets power when key turned to "acc") eg. cigi lighter or radio acc wire.

hold on a sec.. there seems to be a 12v output wire. you could prob try and locate that wire but no doubt will the results be any different.
