## Questions & Answers

**Q: how many amps can the board handle some people are saying up to 15?**
A: The power supply you provide is the limiting factor.  When you say amps I assume you mean amperes?  The amp will draw as many ampere’s as it needs. You can’t force amperes. If you have 15amps at the wall outlet and you buy a power supply rated that high it’s all power reserve at that point. I have a 36v 5amp ps on mine and metering the power it has never pulled more than 3amps at too loud to listen to levels. 

I also ran it on 24v 5a and clipped it once st deafening levels.

**Q: Does this really have tpa3255 amplifier chips? the official xinyi xy-s350h datasheet indicates it has the less powerful tpa3251 chips...**
A: It does use the TPA3255 chip, which has no essential difference from the TPA3251 chip. If you compare your own output power, you can provide the input voltage to about 40V.

**Q: does this support 2 speakers at 220 watts each or does it support 2 speakers both equaling 220 watts?**
A: It supports 2 speakers at 220 watts each but that also depends upon the voltage you use.  If you are running lower than 36 volts then the wattage will drop.  i run mine at 36 volts but be careful because the unit will crash at 38 volts.

**Q: Will it handle 2 -  4 ohm subwoofers in parallel?  (2 ohm load)**
A: Not well. I am using a 4ohm sub and it struggles a bit. 2ohm would be a big ask.  Just wire them in Series instead if you can and go UP to 8ohms.
