I owned an AIYIMA A03 amp below.

It will be great that it can produce more BASS than this from its Left & Right channels (not from subwoofer out). Is there anyway I can get some more bass from it?
My speakers are Two Way 5" Phillips speakers & supply voltage is 19V, Signal from Phone Bluetooth.
Thanks

It's possible that there's a 2-way crossover built in to the tone control circuit. Try adjusting the "BASS-FRE" knob and listen for a change in tone. All the way left should give the most bass if it adjusts the crossover point.
Thanks. You mean adjust the resistors/Cap values in the tone control section (near the BASS controller)?
I meant adjust the knob first to see if it acts as a high-pass adjustment for the speakers. If it does, and all the way left still causes excessive bass roll-off, then a circuit modification would be needed to fix it. I can't help you if that is the case.
