I read up a little more on wiring up power and have decided that I'm going to run one fused heavy gauge wire off the positive terminal on the battery, run that to a fused 3-way distribution block and then distribute power that way.
The Xenarc will still be powered off the cigarette lighter.
Question: How would I go about determining the correct fuse size for the fuses on the battery to distribution block wire, and for the individual fuses in the distribution block itself?
Total number of fuses needed (I think) = 5
1. Positive to distribution block - size?
2. distribution block to OPUS - size?
3. distrubtion block to 100w x1 subwoofer amplifier - size?
4. distribution block to 55w x 4 speaker amplifier - size?
Little help? Thanks.
