How many devices are too much for 12v/remote wire?

[jaymann107 10+ year member]

currently hooked to my remote wire on my Sony headunit I have an EQ, 3 amps ( RF t8002, sony 4 channel only using 2, and stock bose amp for 6x9's) also have a line driver. Now when I turn my volume up to 18 of 35 on the headunit everything except my head unit turns off (EQ, all amps including my stock amp, and I assume my line driver). The only thing I can think is that there is something going on with my remote wire. This all started happening when I hooked the Sony amp up to the 6.5 in my doors. BUT when my RF amp is turned down through the EQ I can turn the headunit up as loud as I want to. I checked all remote iwre connections and they all look good.

Big 3 done in 0 gauge and a run from stock battery to dist block in 0 gauge. from dist block to both amps are 4 gauge.

Any ideas why this might be happening

wire in a relay, i believe this is how it should be wires on a relay

85-Ground

86-Remote turn on from your deck

87-Fused lead from your distro block or other suitable constant +12v

30-Out to all your amps/processors

You definitely need a relay...I wouldn't wire more than 2 things off the REM wire...

Yeah, 2 amps should be fine.

I've done 2 amps and a line driver off 1 remote wire. But I would say and thing over 2 amps and you would need a relay

I've searched for a relay at advanced, do any of you have a suggestion on where I can get a relay that I will not have to order online? Thanks for all the help fellas.
