Help w/ Remote relay wiring for multiple amps

[Lawilt]

I am in the process of wiring 4 PDX amps to a relay switched by my remote switch from my Alpine head unit.

I am having trouble wiring the SPDT relay.

Does anyone have a good diagram for wiring these?

I have it this way now:

87 - to 12v supply

86 - to the remote trigger from the head unit

85 - to Ground

30 - to remote switches on the amps.

87a - not used.

I have checked and my remote from the head unit has 12v when the head unit is on but I can't get it to switch the amps on.

Any help would be appreciated.

Maybe to relay is bad. Looks like it's wired up right.

That's wired right. Check all connections for power, ground, remote with DMM. Make sure you have the remote turn on wire and not a power ant wire from the head unit.

actually, that wiring looks wrong. 30 should be the common so that should be hooked up to the 12 volt supply, and the 87 will be your output going to the amps.

EDIT: Now that I look at it, it looks like you have it wired correctly. Grab a dmm and check your voltages.

he has it wired correctly with 30 as opposed to 87 supplying the amps turn on like southwest suggested. check your ground? i dont know, thats strange

it should work. where are you getting the constant 12 source from?

Will still work the way he has it.

As others have said check that you are on the remote wire and see if the relay is actually changing states when power is applied to coil.

if you are not interuptinga circuit with 87a then 30 and 87 are interchangable.

also, what are you putting the amps in? it has to be a bad ground if you are getting 12v from the blue/white wire.

Beat me to it.
