If I want to connect multiple amps onto one remote lead from my deck, I use a relay. But what do i connect the remote to on the relay?

I was going to use 4 amps.

i hardly doubt u need a relay buddy. your amps should be just fine.

Gmac 08-23-2004 10:12 AM

the remote would got to one side of the coil (the coil is usualy noted as a rectangle with a slash though it) the other side would be grounded.

Could someone post a diagram..i was going to just use an autmotive relay?

Use a Bosch relay 20/30 amp(about $5.00)

pin 86 - input from stereo remote on.
pin 30 - +12 volts ignition - fuse this line, 3 amps should be fine.
pin 85 - ground.
pin 87 out to amplifiers.
pin 87a - not used.

Now for Yuli, dude I don't normally jump on people but with 4 amplifiers running, the chances that the amplifiers will be drawing over 500mv from the cd player is definitely there. It is in his best interest to use a relay so that he does not take out the remote on circuit in the cd player.

^ Yep. I used a relay for the 3 amps, xover and Epicenter in my Avenger. I have burnt out the remote-on circuit before trying to connect too many items to it, had to use the power antenna output instead.

Thanks Rob.

wouldn't your amp only turn on with the radio then?

He only listens to the "oldies" station anyways. [img]graemlins/laugh.gif[/img]

You can hook it up off of constant power also, no? Instead of ignition?

ZachCHartwell 08-23-2004 07:34 PM

You mean the relay..I was going to connect it to my distro block for power..that would not hurt it would it?

Speakerman 08-23-2004 10:06 PM

no that will not hurt it. Just as long as it gets good power from your battery and is turned on by your remote and grounded you will be fine. Its not a big deal at all i just did it a couple days ago. PM if you have any questions.

Speakerman 08-23-2004 10:10 PM

another thing is its recomended you use a 20 amp fuse in line with your battery power and the relay. I didn't even bother but you might do that as well to be on the safe side. Fuses make happy electical systems. [img]smile.gif[/img]

Paul Niwranski 08-24-2004 12:37 PM

^ you "didn't even bother" with a fuse? on a wire from the battery? ouch.

Speakerman 08-24-2004 07:18 PM

haha nope sure didn't. I didn't have one laying around so its on my to-do list okay!!!
