Hey guys,
I have build a couple of speakers so am not new to speakers and sound, but I am new to the nitty gritty details of aplifiers(electronics) on this level. I have just ordered two MA12070P boards from aliexpress. Im sure they are gonna work fine for the orgiginal intended purpose of 4 x 60(80)W outputs into 4 ohms. However, I would like a bit more power for my bas drivers (its a pair of active 2-way speakers using a ADAU1701 for the crossover work). I was considdering ordering a third board and use two of them bridged on for each for my bas drivers and split the last one for the fullrange drivers.
I have seen some talk of using these in PBLT mode for more power, i.e this guy here which unfortunately arent on the forum anymore..
However, after reading the datasheet of the chip: https://www.infineon.com/dgdl/Infineon-MA12070P-DataSheet im starting to get confused. To me it seems bridging it will only increase the available power in 2 ohms:
Is my understanding correct that I will not gain any additional power in my 4 ohm bas driver setup by bridging the amp?
If so, is there any other way to increase the output? Or how are highpower class d amps made? I thought they just bridged multiple chips, but I guess not?
Thanks in andvance for answering my stupid questions xD
Best regards, Daniel
