Would I need a special wire to connect the two tubes?
Lastly, I plan on installing a power distribution block. I am thinking about a single 4AWG wire fused at the battery going to the distribution block then splitting with (2) 8AWG wires. (1) 8AWG wire going to my 500W sony 4 channel amp powering my 4 car speakers and (1) 8AWG wire going to the BTA8250D.
Question about fusing the wires. Could I just install a fuse (what size) at the 4AWG wire coming off the battery, or would I need to install (2) more fuses (what size) for the 8AWG wires coming out of the distribution block?
I know my 500W sony 4 channel amp would need a 40amp fuse. But I'm confused about using a single 4AWG wire coming off the battery into a distribution block and how many fuses and what sizes I would need.
Yes, the BT8014 is the recommended slave unit for the BTA8250D. The power output of the BTA8250D is actually increased at a 2 ohm load (275 watts). The output is then divided between the two units (137.5 watts per Tube).
You will need to install one main fuse near the positive battery terminal, no more than 12- 18 inches away. This fuse needs to be a 70 amp fuse ( the total amperage draw of both components).
Install a 40 amp fuse in the distribution block for your amplifier and a 30 amp fuse for the Tube.
