i read this review of Infinity 12d VQ on "Car Audio and Electrion"

" I installed two Crossfire VR1000D amplifiers with a bridging module. Doing this will allow me to wire the 12d VQ's dual 4-ohm voice coils in parallel for a 2-ohm load. Two Crossfire VR1000D amplifiers wired with a bridging module at 2 ohms will deliver a throbbing 2000 watts of power!"

i want to have the same set up. How do i connect the wire 2 amp to 1 sub?

 

That is referred to as "strapping" the amps together. Check this out...

Just wire one amp to each VC...

 

thanks for the replies.
I got one of the amp now, waiting to find another one ebay

 

bad bad idea, you need to make sure the amps are strapped so that you don't send different voltages to each voicecoil and blow out your sub

 

I wanted to say the same thing but I wanted someone else to say it first! But then again he wanted to build a 9cube box for 2 12s...

 

It works fine if you do it right, you don't have to strap the amps in order for it to function correctly, you simply have to make sure both amp's outputs are at the same level. Either way is fine.

 

yeah but if you're off at all the sub will be fubar'd

 

Real difficult to wire the subs up with the same ohm load. Anybody wanting to push this kind of power should at least know the basics of electricity. Voltage doesn't fluctuate per amp, it fluctuates throughout the entire car. Unless you have extra batteries, but that's a whole nother story.

And I don't recall wanting to build a 9cube box for two 12s? I recall posting a diagram showing two twelves, and saying they would be much better off with 15s. Bracing would be required in the box, significantly lowering the cubic feet. I've done more number crunching since that thread. With bracing and some beefy 15s like the one I have sitting in the garage, should come out to about 3cubes per sub.

 

And I just thought this thread was going to be a joke about 2girls 1cup.

 

LOLOLOLOL just about


Well back to the OP...either strapping amps or using a maxxlink, safest bet.

 

I am so happy I wasn't the only one that thought about 2 girls 1 cup...

 

hahaha,
i should have named the title "1sub power by 2 amp" instead.

Thank for the help. I just read the manual, It said each VR1000 need 1 battery.
I don't think i will put 2 extra battery in my trunk.
