I've got one from another brand, but is 100% identical except for the name on it.

When used with the compensating-diode in there for optimum voltage, it's just the best solution for a good power- supply to your install IMO.
[and you'll never have to ask others to give you a push after showing off your sound].

"When used with the compensating-diode"

The connection with the blue dot [the smallest one] is to be connected to your alternator.
The feeler of the stock regulator of your alternator must be disconnected.
This way, the alternator regulates it's voltage to the load connected to the diode-block.
This ensures 14.4 volts on both battery connectors.
If you don't use this terminal, you will see a voltage drop of app. 1 volt on both battery-connectors, meaning you will only get 12.8-13.4 volts to your battery's.

Get help of your local car- elecronics shop, how to connect this type of diode-block on your alternator!
Once installed properly, you'll have the best solution for charging two battery's with one alternator.
