## Questions & Answers

**Q: Please provide a link to Wuzhi App, since there is no manual.
Is there any?**
A: Download link for Wuzhi Audio APP for Android mobile phones:
 http://www.qingdaowuzhi.cn/appdownload/Wuzhi_Audio.apk

For Apple iOS mobile phones, please search "wuzhi audio" in Apple App Store to download and install.

**Q: There are two versions of these. does it use tpa3251 or tpa3255? what is the minium supply voltage?**
A: Using tpa3251, the minimum supply voltage is 12V DC, and the current should be greater than or equal to 10A.

**Q: will this amp work without the app. Or do you have to have the app for it to work?**
A: I did download the app and ran it once.  Never clicked on it again.   Seems to be a bluetooth amp so you pair with it and it doesn't need an app.  It does sound pretty great.  You can easily talk with someone while extremely loud music is playing.  I have low-end Klipsh bookshelf speakers and a Polk 10 subwoofer.

**Q: Could I run two 5.25" woofers at 2 Ohm well/safely (paired in parallel), or do a series at 8 Ohm? Woofers have a rating of RMS 50W/MAX 100W at 4Ohm.**
A: The subwoofer one way can support 2 ohms, but the stereo there is a minimum of 3 ohms, otherwise the amplifier is easily protected. Speaker resistances greater than required are fine, mainly the lower limit. You can connect speakers in series and in parallel.
