When I jump a wire from the +12v to the REM section I measure 3V at the +12v section. What is going on here? I don't want to eat $260 and pay another $140 to figure out it was a bad amp and another $150 to buy a new amp...
New Development.
I did something I should have done before I wasted all my supplies. I used the power/ground/rem/rca's from my sub/amp and connected them to the new amp. Well, this powered the amp right up fine. However, I'm not getting sound, or very loud sound, from my speakers. They are playing but you have to really crank it up to get even audible sound...What could be the issue? And yes I moved the rca's to the front section on the head unit.

In fact, we actually all have incentive to AVOID shielded RCA cables. Why? Because the shield itself is a conductor. If the shield has a gap anywhere, allowing noise to be introduced at any point in the shield (cable is running along the car body, body has a lot of current flowing through it all the time, as the body is the car's ground point for EVERYTHING), then the shield will transmit the noise the entire length of the cable, resulting in a greater potential to introduce audible noise. That can't happen with non-shielded cable, and since a twisted-pair design does such a great job at rejecting noise, I suggest avoiding shielded RCAs.
Not arguing, just presented for what it's worth, do whatever makes you happy.
Take a speaker and get a foot of wire and wire it directly to the speaker terminal of the amp. Plug the RCAs into the amp input, put your volume around 50% on the HU and play music. It should turn on and play music. If the volume is low, you can adjust the sensitivity/gain on the amp to increase the output. Does it do this?
Ok, I took it down and got it wired up and everything. Now I have another problem. When I turn on the stereo and keep the volume low so I can here other things I get a horrible nnnnnnnnnnnnn sound coming from the speakers. It starts when I turn the key to On or with the engine running. It stops when I turn the key to ACC. Anybody know what kind of noise this is? I have a Pioneer deck. It doesn't increase with volume and it doesn't change pitch with acceleration.
The noise wasn't there before. When I unplug the new rca's the noise goes away, with my sub/amp rca's still connected. When I plug the new ones back in, I get the noise.
Plug what in somewhere else? The rca's or the deck?

its possible ur having the pioneer ground issue... you could try this:

I did this

but I didn't ground it the same way they did. What I did was took the other ends of the wire and put them under two screws on the metal casing of the deck. Simple, but extremely effective. I did this only to the new ones and the noise is gone.
