Motor cuts out or doesn't move enough when used with amp #1

Amp: GF1002 http://www.aliexpress.com/item/Free-Shipping-PAM8403-mini-5V-digital-amplifier-board-with-switch-potentiometer-can-be-USB-powered-GF1002/2017523062.html This amp cuts out whenever I try to use it Have tried: Powering with 5V battery pack, 4 AA in series The amp also cuts out when I try to use it with the copper coil, but it worked on a copper coil before with the 5V battery pack so I'm not sure why it's cutting out?

When I use the Kemo Amp (Kemo #M034N 6-16V, 40W - http://www.parts-express.com/kemo-m034n-40-watt-universal-mono-amplifier-module--320-554 ) I hear the sound but the motor doesn't move enough to vibrate the fabric in sync with the music

Shure has suggested using a LiPo battery, so I might try this one http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=48783

But I'm not sure the motor is strong enough even with this.

Why is the amp cutting out?

I tried a LiPo battery 3.55V through the GF1002 and the motor still cut out when run through the amp. runs fine without amp. Have tried different motors and the same problem

The battery is http://www.sb-lithium.com/lithium-ion-battery/shenzhen-manuafcturer-wholesales-li-ion-battery-3400mah-mh12210-ncr-18650b.html

Which has a maximum discharge of 1C = 3.4A img_8027

11.43 V LiPo doesn't work on the Kemo amp... but it should - not sure what the C value is though.... I'm currently charging all the LiPos to see if they were discharged, but I was pretty sure they were charged img_8026

The 11.1 V LiPo battery when charged and connected properly worked fine!
