Review: shockingly good - I use this in my warehouse/man cave using three (old) deep cycle batteries to take advantage of the 36v high watt output. I didn't really notice a quality or volume improvement by upping the voltage from 12v but it works great!. I power an old JBL home theater woofer and some leftover Bose bookshelf speakers and this thing cranks! I have 20' ceilings and the sound is loud and clear as a bell! It is used every day at almost full volume with minimal distortion. Heat can be an issue because it does get hot but it hasn't faulted yet.
Review: Excellent - Excellent

## Features

- 【TPA3251 HIFI CHIP】The XY-S350H power amplifier board uses two TPA3251 power amplifier chips.Support wide voltage input:18-36V, power up to 220W*2+350W (PMPO).
- 【TREBLE & BASS CONTROL】If you are tired of an amplifier with only one volume knob, then you feel right, because you have further requirements for audio. By adjusting the high and low frequency knobs of the XY-S350H power amplifier board, you can make the sound more layered and make the bass more shocking.
- 【HIGH COMPATIBILITY】The DC adapters on the market (plug size 5.5mm*2.1mm) can basically meet the needs of the XY-S350H Bluetooth power amplifier board. If you don't have a DC plug, please don't worry, you can also directly connect the positive and negative poles of the wire to the power socket of the amplifier board.
- 【PROTECTION FUNCTION】XY-S350H Bluetooth power amplifier board has multiple protection mechanisms to ensure its safe operation. With short circuit protection, undervoltage protection, overvoltage protection, clipping protection.
- 【IMPORTANT REMINDER】the working voltage of the power amplifier board must be above 18V. DC voltage lower than 18V will fail to start the power amplifier board.

## 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.
