do i need both power and grounds hooked up?

[Slumpin 0]

i've got a crossfire vr2000d thats supposedly been modded to be .5 ohm stable and handle high voltage. it has 2 hookups each for power, remote, and ground. these all need to be hooked up right? how can i test the amp beforehand to see if i can run it daily at 1 ohm? it should do around 2800x1 @ 1 ohm, and i'll be using 1800-2kw of that for my 12's, so it wont be running full tilt but about 2/3.

anything else i need to know before firing up this beast?

It should run daily at 1 ohm, just watch it.

They also dont need modding to be run at .5 or for high voltage.

Yes you have to hook up all of those powers, grounds, and remotes.

ok heres my (rather expensive and heavy) wiring setup. i've got a 1/0 wire from the positive battery terminal back to a fused splitter to 2 4 gauges. the fuse by the battery is 200 and 120 each at the dist. block.

have a 4 gauge power wire from the battery terminal straight to the diamond amp, with an 80 amp fuse by the battery and 3 30's in the amp.

a 1/0 gauge wire from the negative terminal to a 3 way 4 gauge splitter in the back, 2 to the crossfire and one to the diamond.

i can just split my remote wire into 2 at the back by the amp right?

have i got all my bases covered?

Yes that should be fine.

You may need a relay for the remote turn on though.

Try it out first.

Good amp choice.

i dont understand about the relays, could you explain?

It basically adds a power distro to the mixture. The main remote line only really has enough juice for turning on around 2 amps. The relay adds more power to the line.

Here's what you do. The relay has several pins on it, one of the pins you wire the existing remote too. Another recieves constant power from the battery (new little line). There are several outputs on it as well. Those go to the amps.

Just ups the out put of the remote basically.

can i pick one up at radio shack or something? any specific kind i need, or any 12v relay? what if i just try splitting the one remote into 3 wires? can't have too low of a remote voltage right, its either on or off? im guessing i need 12v showing to each one to turn the amps on?

You actually can have to low of a remote voltage. that's why people use the relay to bolster the original signal.

Radioshack has them, I'm not sure of the exact part number. But most 12v relays that split one incoming signal to two or more others will work.

I just use a standard SPDT relay and use the remote for the sense lead, and will just parallel all my remote wires off the switched output of the relay..

Speaking of relays, I have a technical thread I need to post in the advanced section.

Also, as far as the power and grounds, if the amp has a single power supply, which I doubt, then one hookup will be fine, assuming you can fit a cable in there large enough to support the load. I'm assuming it has dual power supplies though and each one is probably fed independently hence the dual inputs.
