Remote wire to 3 amplifiers.
#42
Hi,
I went to my local electronics shop today to pick up a relay. Well they had many to choose from. I was not sure which to get. Some had five posts and some had four. The ones with four posts were missing the 87A which i dont seem to need so would it be a good idea to get that one?
Also, some were 12 VDC and some were 14VDC, what is the difference?
Also, some were 20A, some were 30A and some were 40A. Which one do i need?
Thanks for your help.

the 12v 20amp relay is all you need.Each amp draw approximately 200 mA. So anything over 1 amp should be fine for all three of your amps.a 20 amp relay is just fine.
(and no worries, you cant damage anything by using a 20 amp relay when infarct you only need a 1 amp.)
Im using a 12v 30amp relay for my system. Im running 3 amps,4 fans, and 2 LED lights all off the one 30 amp relay.

what about the 4 post one versus the 5 post?

you only need the 4 pin relay but any one would due.
hook 12v(+) to pin 30 (make sure you fuse this wire)
hook Ground(-) to pin 86
hook the 3 wires for the amps to pin 87 NOT 87a.( 87 supply's power when the relay is on)(87a supply's power when the relay is off)
and hook your remote wire from your deck to pin 85

My two JL Slashes have a remote from the front going into one of them, and then a jumper wire from that one to the other. No Car alarm installed. Should I relay these or are they ok as-is? If I another component (Audio Control EQS,) should I then begin considering it?
If I should get this done... are there any Car-Audio branded relays that look a little nicer? Or are nicer to mount to my amp board?

^^all the info is in the thread for you to decide if it's worth it or not. Personally i would just fuse the remote wire with a small 1 amp fuse for the 2 amplifiers. More than that I'd use a relay. In my case i have 5 components that need to be switched so i have a relay and a fuse.
