x2. that'll tell you if it powers up so just hook a speaker to one of the speaker leads to test the internal amp.

x3, i usually get some speaker wire and connect the black wire to one side, the red\yellow wires to the other side and the black wire side goes to the battery -, and the red\yellow side goes to the battery + side, and cram them on (or use alagator clips if your special) and then pop a disc in and sit ther ewith each speaker terminal and test all the outputs on a spare speaker //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
