I'm trying to make a very small practice amp for bass. At this stage its just the bare minimum to see if I can even do this hobby so tone board isn't in play yet.
Here are my questions about this board: https://s.lazada.co.th/s.8Mmyt
1. The data sheet (from ti, not sure if it applies here) says it can handle 30 watts into a mono load from a 16 volt supply, but it's recommended operating range can go up to 24v. How will going above 16 volts affect the chip?
2. The specifications for this board says 3A max. How do I find the mimum amps this can run on?
My plan was running a variable watt / amp power supply and raising voltage / lowering amperage until the audio sounded better or stopped working but I have no idea what I'm doing.
3. I've heard this chip is quite good at amplifing low signals so would a boost pedal be enough to get my instrument level to line level? not, whats the simplest way to go about this?
I really appreciate anyone who replies. Literally never even held a soldering iron or changed a fuse but got this urge randomly and cant shake it. Sorry if this is answered on the data sheet. Its my first time looking at one and its overwhelming.

Hi and welcome to the forum!
1. I see the operating voltage range quoted as 8 - 18 V DC. The higher the operating voltage, the greater the output power capability of the amp. https://udvabony.com/product/tpa-3110-audio-amplifier-board/ The output power is quoted as 15 W x 2 at an operating voltage of 15 V DC and this is the voltage I suggest you use.
2. The higher the volume setting, the greater will be the current drawn from the voltage supply, varying from a small idling current up to a maximum of 3 A. The 15 V power supply you use must be capable of providing the maximum current of 3 A in order to get full power from this amp.
3. I believe a boost pedal would provide a signal that is sufficient to drive this amplifier.

It would push the chip to work harder and result in a greater production of heat.
Best to run the amp at a conservative 15 V DC rather than taking the risk of over-stressing it with a higher voltage.
