I found this preamp board on Ali that has most of the features am looking for. Confused about a few things. The diagram is really low resolution.
1. Failing to see the subwoofer output, does it come out of the 5 pin connectors? If so will a 26AWG connector suffice?
2. Would like you use the same power supply for amp board. Its asking for this. " Power supply + v G -V is the power supply port, connect positive and negative dual power DC +/- 12v, or +/- 15V." Planning on getting a Mean Well LRS-350 9.7A.
a. Does Dual power mean something else beside + / - V and ground?
b. What is the best way to reduce the voltage from the powersupply?
(will this work): I was thinking about using a LM2596 DC-DC Adjustable Buck Converter 3.0-40V to 1.5-35V Power Supply Step Down Module. But It states "Keep it under 2.5 A and use the heat sink when working for long hours." Does this mean I have to reduce the AMPs before connecting it? There is no ground on this Converter, do I just use the ground from the power supply? Do I even need a ground?
Thanks

1. The Sub out is on the 5 Pin connector.
2. It needs a +/-12V up to a +/-15V symmetrical power supply.
3. The power supply does NOT supply a dual voltage, which means, you can not use the PS! Neither the Subwoofer crossover nor the vast majority of other preamp or crossover circuits.
4. Your DC-DC converter will not work because of the common ground.
