I have 2 amps in the trunk. I'm running them off a relay. I have the head unit remote wire that runs to the realy then the realy that runs to the remote turn on leads on the amps. Just wondering if the constant 12V power that the relay needs can be simply run off one of the fuse distribution block for the amps. Can I just strip strip the end of the wire thats plugged into the 12V lead on the relay, twist it in with one of the amp 12V power wires that attach at the fuse block and tighten the fuseblock terminal to hold them both?
yup. (and yes, i understood what you wrote
)

You sure can, that's how I run mine.

How big of a relay did u use??? 30 amp.....40 amp???
Thanx
*sorry for the mini thread jack*

lol a regular 30 amp relay will do, those remote turn ons wont use more than 1 amp (and thats for like 3 amplifiers hooked up).

Thanks, Yup 30amp is the one I used works fine. Just wanted to make sure that setup was ok.

O-ok. Thanx. I heard before that they used around 8 amps so thats why i was wondering.

30 amp is plenty. remember, your remote turnon only needs milliamps to turn on the amplifier or device.
I used to have all 3 of my amps running off a single remote wire-- no relays, just daisy chained together..
No probs.

might not have been a problem for you..but not all headunits and amps are the same...
That's like a guy saying " I had my 14awg power wire ran through my door jamb and hooked to the battery with bread ties..no probs for me!!"
see my point?

I chose to use a relay. I heard you can damage your head unit running all three off the one remote. So didn't want to take any chances. By the way anyone know if it is possible to damage your head unit like this or is it that simply your amps won't turn on if you run to many off the one remote wire.
If you have something that requires more power than you can put out, ugly things tend to happen.
quote BCAE...
Remote Input Current:
The remote input current for amplifiers varies with the amplifier and the model. Some draw minimal current. Others draw a little more. The upper limit of a properly functioning amplifier is approximately 50ma (0.05 amps). If you're using/controlling more than 2 amplifiers, it is (in my opinion) much better to use a relay to control the amplifiers. Actually I really prefer having a relay in the remote circuit (no matter how many amplifiers I'm using) because it protects the head unit's remote output circuit in case of a short circuit.
Note:
There is at least one very popular brand of amplifier that draws as much as 500ma of current when the amplifier fails. This is enough to damage the remote output switching transistor in the head unit if the fuse is missing or is of the wrong value. A relay in the remote circuit will completely eliminate the possibility of damaging the head unit in this situation.
