    Post turn on wire for amps

    okay i seem to have everything all set to go i just am kinda stumped at how i'm going to work the amps i mean how do i simulate the remote turn on wire that the head unit in a normal car would have?

    by the way i'm doing away with the traditional head unit who needs it anyway!

    You could take one of the 12V sources from your computer power supply. So when the computer goes on the amps go on.

    Either that, or get your wiring diagram and just tap into the ignition acc wire and send her to the back (or where ever).

    but isn't the voltage and wattage going to be to much for the amp to get rid of or does it matter?

    If you just want 12 volts for the remote switch on the amps then it doesn't matter. Its just a relay switch that only uses probably a couple hundred milliamps if that.

    I think. =)

    If you're running it all the way from front to back you might want to fuse it with a 2 amp fuse or something like that.

    Schrodos is right... the remote turn on lead doesn't power your amp, it just flips the switch. You should have a nice fat 4AWG wire running from your battery to a distribution block & then power whatever you need from there.

    Cool

    If you are using the computers DC power to turn on the amp, remember that you will need a common ground. This can cause problems (noise, blown fuses, fires, etc... :-) so you may just want to connect it to the accessory wiring, or the switch that turns your DC-DC/inverter on.

    thanks guys i knew it was just a swicth type deal so if i just used the same switch i used to turn on the dc-dc converter it should work fine? and i do have a phat wire coming for the main power line thanks that's all i needed now just to sit and wait for parts to make all the circuitry this is going to be the toughest part i'm very impatient!!!
