Hi all, new to the page. I had a question regarding amplifier boards, speakers and the use of capacitors.
Normally i use the 5v BT Amp boards like a QCC3003 from aliexpress, step up the voltage to 6.5v to get the full 5watts per channel that is advertised for little 3d printer BT audio projects. Recently i went and grabbed what is a QCC3034 amp, which apparently have a boost converter in there to get it to 8watts per channel. Sounds great having a max of 5.5v to get 8watts out of a speaker right? wrong....when using bass heavy music, which is the test and full volume, the step up modules taking it from 3.7/4.2v to 5.5v gets a decent surge which drops it down to 1.5v ish. I know the speaker drivers cannot go to the frequencies lets say below 70hz, so wondering if putting a capacitor on the speaker's positive would reduce/restrict this crazy brown out from happening?
