30A relay on remote turn-on wire

[shizzzon 10+ year member]

I just wanna make sure I don't damage somethin.

I have a 30A relay on the remote turn-on wire.

So can I wire leds(about 10ft- draw is 1.6 amps) to the relay and be good to go?

And basically, I can hookup as much as 30A of draw to this thing without damaging the stereo?

relay isnt a fuse...

you are doing this so you can turn your amps on and off correct?

not a bad idea...but why dont you just go to walmart and buy a toggle switch for $1.50 and wire it up and call it a day?

just my $.02

How do you have the relay wired?

i think he's wanting to hook up more things to his remote wire, so other things (amps, etc) turn on with the HU. the HU remote wire only can turn on so many things, so he wants to hook up a relay to it, so its able to power on more devices

Connect pin 85 of the relay to the radio remote turn on.

Connect pin 86 of the relay to ground.

Connect pin 30 of the relay to battery power.

Connect pin 87 of the relay to whatever you want on with the radio.

The relay isolates the radio from the load. You can connect whatever you want to pin 87 as long as you do not go over 30 amps. Even if you go over 30 amps, it will not hurt the radio, it will just damage the relay over time.

do you have to fuse pin 30?

I fuse anything that is connected to battery power. . . .

what size fuse would you use for a 30a relay, becuase im about to add a relay for my amps/3way crossover/fans for the amps too..

I would think you could run all that on 15 amps and 16 gauge wire.

The coil wires (pins 85 & 86) are less than one amp, so they can be really small wire.

this is most likely what ill have.

5, most likely 6 amps

a 3 way crossover.

maybe a fan for each amp, at least on the 2 3kw amps, maybe not so much on the smaller 2ch's

Yea, I had this thing wired for me when my dvd player was being installed.

I gotta take it back to the shop since he installed it and see what size fuse but more importantly where the fuse is for future reference.

I'm mainly using it to power 3 amps and an inverter.

Thanks guys for lettin me know.
