Relays (Multiple Amplifiers)

[Chevy350TPI 12]

I know you're not supposed to run more than one REM wire from the single one off of the head unit, but I'm kind of (read: really, really) crunched for time at the moment - it would just be a small component amp and the subwoofer amp.

Not that much of a current draw... will be fine to wire both on one REM.

[Chevy350TPI 12]

That's always nice to hear.

I've always used the SoundDomain relays in the past, and didn't want to find out the hard way that the REM wire doesn't like two amps hooked up to it.

Should I fuse both runs or take any precautions?

[ANeonRider 3]

Just run the rem to one amp, then from that amp to the next.

[Chevy350TPI 12]

Yay ... one's in the trunk, one's under the front seat

[ANeonRider 3]

ahhh, makes sense. I don't have a fuse ATM, but that is always a good idea. Fuse em.

[Chevy350TPI 12]

Or I could always do it your way and not have to drive somewhere to get fuseholders and fuses Which is probably what I'll do unless someone highly suggests I do it another way.

I think the smallest fuse you can get here is 0.5 amp (the glass ones) ... so I might just run two wires and fuse both of them.

[ANeonRider 3]

Fuse em later then

im going to use a relay whenever i get my 2nd amp in

[Tirefryr 1,742]

I don't use a relay unless I absolutely have to. Don't want to take a chance on introducing any noise into the system. Now with that said, I ALWAYS fuse my remote lead. a simple .5 amp fuse is plenty. If that blows, then you know you need a relay. Most amps only take a couple milliamps to turn on so you should be fine. But that fuse is a lifesaver. Ever accidentally touch the remote to ground? Use the fuse.

heh, ive done that before...only sparks a lil bit.

i just daisy chain mine...no problems so far.....

[ngsm13 1]

I used three amps, AND the eclipse balanced line adapter at one time. So FOUR units, never say a drop in voltage...never had any problems...

If I'm going to have two runs coming off of that main REM wire, should I fuse both lines or just the main one before it splits?

[Supa_c 1]

waste of a fuse IMO

You can never have too many fuses in a daily driven vehicle IMO.

So that's a yes for a .5 on each run?

[mrray13 30]

i usually just run a single short one to the first amp, then split it off from there. i've never fused my REM wire, though nick has a point. u can't have too much protection, but then again, never fused, never had an issue...so i guess my whole post is useless..lol..

so what else is new?

wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

Yes, with rem's I think of the incindiery carpet & countless other wires that I wouldnt want to melt. ...and, of course the output of the HU.

I voted earlier.

I personally would just do one fuse on the main wire. If there is going to be an accident on either of the two branching off it, you can sure bet it will be greater than 1 amp. That's what's needed to blow the fuse so you should be fine. IF you feel the need, you can use 2.

i'm running all 4 of my amps off a single run and then i just daisy chained em

no problems so far

[Aaron Clinton 2,372]

for lower power installs, jumping from one amp to the next is ok from my experience

[Chevy350TPI 12]

Ran both off of the single line from the head unit with one .5 amp inline fuse. Works great

Frickin' loud, though.
