I have the rockford fosgate prime 1200.1 and the prime r2 500×4 channel amps. I have Shuriken 1250 power cell in the trunk. I use 0 guage wire to power to distribution block. My question is I have a 200 amp fuse under my hood do I use another 200 amp fuse before the power cell battery in my trunk?
 
Yes. If the power wire ever shorted out and you didn’t have the rear fuse. The front fuse would blow, but the rear battery would still be connected to the short.

Like this... The fused cable is going in to this UltraCap. The other power cable is going to fused distribution blocks.

Thank you for the visual. So just fuse my main battery back to the power cell and then a line off that to a distribution block.

It would be cheaper, it might be easier to find a place to mount it, and you would have a ton of options if you just do two, 3 slot fuse holders...

My bad, yes, I read them each as having two 4ohm coils. The JBL diagram left a bit to be desired, IMO. ;) And a double yes, thought U was talking...

I plan on getting the fuse to run as a front sub/midbass in my kick panels...I've heard they sound good but you definitely wont get mirror shaking...
