So as mentioned in my previous post, the new dsp amp had arrived, along with all of the professional grade OFC wiring, and accessories such as the fuse holder and a fused distribution block (power in/out from battery, and then split into leads for two amps - one for immediate install and the other for a future upgrade as needed).
I had decided that I would mount the dsp amp in the space next to the battery, but this meant no space to install the distribution block in the same space (having placed the dsp amp in the space just to make sure it fit).
Looking around, I realized my choice was either to mount the block below in the tire well, OR in the space where the jack used to be (no jack because no spare due to the R35 calipers and rotors). While it was tempting to mount in the tire well because it would call for less wiring, I was concerned that there was nothing to solidly mount the distribution block to. And I'm not about to drill holes into my car. Ever.
|With both the battery and the amp nearby, theoretically this is a good spot to locate the fused distribution block. |
But no existing holes or bolts to attach to.
On the other hand, in this space:
|Green arrows point to potential existing mounting points|
|I also bent the ABS up in a lip shape at the end|
|And drilled two holes in the lip to clear the bumper bolts|
|So maybe here? Shifted to the right (top) side as |
we would need clearance for cables on the bottom
|Close up, you can see that the left side is bridged for the ground wire coming into the center |
while the right side has a fuse for the power line between the center and the output terminal
|This is a 1/0 AWG cable - for power and coming straight from the positive battery terminal so it's red - and you can see I have added another fuse for the remaining positive terminal. |
|So the red is positive, and the black negative. Center wires are 1/0 AWG while the output red and black wires in foreground (that will connect to the amp) are 4 AWG|
|And here it is, installed. Fits perfectly, is solidly mounted, |
and all the cables clear the felt trunk liner (I tested to make sure)
