Dear Joom Team The TCM2208 drivers cannot be used because the connections have been soldered on incorrectly (see photo). Thus, the Vref voltage cannot be set on the driver and the heatsink is in the wrong place. You can see how it should be on the 3rd photo (Image-2.jpeg). Send me 4 new TCM2208 drivers that are correct. With kind regards Heinz Leukel
top product , I am impressed with the product +i recommend use 8 Ohm speakers or two 4 Ohm speakers per channel in series (not tested) +I tested 2 speakers of 20w plus 2 speakers of 30w plus 2 tweeters all in parallel and all 4 Ohm , still normal, but not enough amperes (I tested with a 19V and 3A supply) +I come back to edit the review after testing with 24V 6A
