one remote turn on, 2 amps?

Ok, I have a problem. I'm probably just an idiot, but I am having issues getting my single turn on lead split into two for the two amps. I hooked up my amps this afternoon, and I tried splicing the turn on wire into two, by twisting the wire around the original, and then soddering them together. It looked kind of funky, but it should have been a good connection, or at least I thought. so. I turned the key on, and neither amp came to life. I cut out my splice and butt connected the wire into a single wire again, and connected it to one of the amps. This time, it turned on, so my attempt failed at some point.

What is the proper way to do this?

You need to be more detailed. As it is I can't really understand your post.

I cuurently have the remote lead from my deck to the Nak amp, then from there  to the MTX amp. I will be putting in a relay soon.

If you experiencing problems aside from this you may consider a grounding problem. Meter the switch lead at each amp.

I will clarify:

I had a single amplifier running my sub. I had run a single remote turn on wire from the head unit to the amplifier and all was well. Now, I am installing a second amp. I need to run turn on leads to both amps. Today I took the original turn on lead, and a second wire and attempted to splice them together by wrapping the wires around each other, and then soldered them together. Basically, I ended up with a "T" connection. I ran one end to one amp and the other end to the other amp. Neither amp turned on when power was applied. That's about as clear as I can explain it, hopefully that helps.

To check if the connection was faulty, I basically spliced the  original wire back together again and connected it to one amp and then the amp turned on. So, it was my splicing job that was at fault. I didn't try piggy backing the wire from one amp and then from that amp to the other amp. Do you just connect the wires to the same remote screw on the amp when you do this?

I think I will try this method, thanks....

Not necessarily.  Although that could be the problem, you wouldn't know because you didn't test each wire end one at a time to the same amp while the wires were still connected.  Or you didn't check continuity with a meter.  It could be an insufficient power supply instead and so a relay would be needed.

I didn't think to use the multimeter to test the voltage from each end....I'm still learning the electrical side of this. I am still pretty sure it was the connection, but of course I could be wrong. I will try a new connection tomorrow, and see what happens. I am not sure why the power supply would be insufficient, unless the splicing reduces the voltage that much.

If I need a relay, where would I get one?
