  • 2.3 Ohm speakers on DUDU7

I have a DUDU7 purchased from Aliexpress mekede store and it was described to have the TDA7808 Amp chip and the data sheet says it knly support 4Ohm.

I want to purchase a pair of JBL 6x9 that are rated 2.3Ohm. Just wanted to know if those will work well on DUDU7?

Any heating issues or anything that I could face?

    abidali 4 x 27 W 4 Ω @ 14.4 V，1 kHz，THD = 10%
    4 x 47 W 2 Ω @ 14.4 V，1 kHz，THD = 10%

        dudu-lai I tested 3Ohm 6.5 inch front JBL speakers, and they run fine. Maybe 2.3 Ohm 6x9 is too much for the head unit?

            abidali Yes, it runs, but it doesn't run well.

              abidali вам нужно использовать динамики не ниже 4 Ом.

                  Chubaka885 The manufacturer says it becomes 4ohm with impedance of wire.

                      Someone told you a story.

                          Teklock It's been 2 months and the 3ohm front components and device work well so far. Not sure about disadvantages in the long-term use but I'm planning to add an external amp for the speakers soon. Didn't go for 2.3ohm for this device yet.
