gismo dudu-lai interesting - the 888 board uses the TDA7808 and in discussions I've read it only supports 4 Ohm. The datasheet seems to support that https://www.st.com/resource/en/datasheet/tda7808.pdf That said, my speakers (https://eton-audio.com/ug-vw-t6-f2-1.html) are 3 Ohms and work fine with my DUDU7 - and they go down to about 30Hz no problems.
abidali Asking this, since I'm about to get JBL 6x9 for my Corolla, that are rated at 2.3 Ohm. Will those work fine on DUDU7 8GB? Is DUDU7 with 7808 chip 2Ohm stable? Purchased from AliExpress Mekede Store, stating it has TDA7808 Amp chip.
