usmc7980 Posted August 8, 2008 Report Share Posted August 8, 2008 I'll be hooking up amps soon and was wondering if I need to use a relay? I have 3 JL 500/1 and ? for mids and highs(probably a Sundown 100.4) So will I need a relay for the amp turn ons or can i make a distribution bar then split it off to the amps?

jhmeg2 Posted August 8, 2008 Report Share Posted August 8, 2008 (edited) If its gonna be for power I would use a distribution block. If its for remote, a relay. I acctualy went a little beyond what you need, and picked up a PG DD5. this thing is great. It has a variable delay for turn on and off up to like 8 sec. It rally helped with a turn on "pop", of all the equipment comming on at the same time. If its gonna be seen I would do it this way, other wise a little relay setup thats hidden with do the trick.

MECHMAN Posted August 8, 2008 Report Share Posted August 8, 2008 Use a standard 40amp relay, it will keep the stress off of your head unit, and will supply a better turn on signal to the amps. You can get them anywhere for less than $5. Quote 1-888-MECHMAN www.Mechman.com [email protected] Link to comment Share on other sites More sharing options...

usmc7980 Posted August 8, 2008 Author Report Share Posted August 8, 2008 I am talking about the remote wire and not the main power. I figured on using the relay but wanted to make sure it was called for, so a relay from AutoZone would work fine? Quote Link to comment Share on other sites More sharing options...

ptcary Posted August 8, 2008 Report Share Posted August 8, 2008 (edited) I am sitting on the fence on this one, someone posted here on SMD that a diode is needed across the relay to keep it from potentially spiking back to the head unit and damaging it. I have a message sent to Eclipse to see what they say about the remote turn on line on their head units. I'll post their response. Anyone have any definitive answer on this?

ptcary Posted August 8, 2008 Report Share Posted August 8, 2008 Ok, I'm back and Eclipse says Yes, use a relay, so I guess I will go ahead with one, but probably no diode unless I read more about it.

ptcary Posted August 8, 2008 Report Share Posted August 8, 2008 (edited) Ok guys, here is what I found on 12volt.com http://www.the12volt.com/installbay/forum_...e+turn+on+relay It says to wire a 1 amp diode, (cathode stripe side to 86 and anode non-stripe side to 85) to keep a possible voltage spike going back up to the head unit remote wire and damaging the head unit. Anyone understand this stuff better? Can we just solder a diode across the relay?
