SSM3302

I have the Eval Board for the SSM3302. I removed the filter capacitors and inductors as it states on page 3 to operate as a filterless amp. Both channels are enabled. Power is supplied from a +12V supply that I verified in advance  can supply a minimum of 8 watts continuous power. I have two 8ohm speakers (Atlas SM82T-WH) as loads. I have a current meter between the +12V supply and the eval board to verify power levels. I have not been able to achieve the supply current as seen in page 11 of the spec. sheet for a +12V supply. I have no problem delivering 8 watts with one channel enabled. With 2 channels enabled the best I can do before the amplifier begins to shut on and off is about 100mA. What am I missing? Ed
