Hey guys, I'm quite new on this diy thing.
My friend gave me one phonic p8a without an amp and recomended me to buy two tpa3118 4-8 ohms with 60 watts and dc 8-24. One for subwoofer another for the tweeter.
However, the chip burned on all of my attempts to make it work. Except for my last attempt, which I solded both the tweeter and subwoofer on one amp output and it worked for a longer period of time.
So which amp should i use, I've been thinking on buying tpa3116 with 100w, but im not sure anymore.
as far as i know the phonic p8a tweeter has 4 ohms and the subwoofer has 8 ohms.
And i used a font of 20v of output

You need a crossover.
Either passive (speaker level) or active (line level).
If active, you also require a tweeter protection capacitor.
Without a crossover, you will certainly burn out the tweeter.
You don't say which driver burnt the chip.

I see. I'll look for one
On my last attempt, the amp that was only connected to the input and power burned. But the one with all the output is apparently doing fine. I believe the failure happend because i soldered one of the outputs badly. But now when i turn the speaker on, the burnt amp just keeps burning
I'm trying to replicate what i did that work. But i was looking if there are more reliable amps.

So you have one amp that you wired badly and destroyed it.
You can only destroy it once - once it is toast, no amount of trying again will make it work.
You have a second amp you managed to wire correctly and it works.
Just take more care and buy a replacement for the one you burnt.
Don't buy a more expensive amp until you are confident of your ability to connect it correctly.
Ensure the speaker drivers are wired independently and do not share a common ground wire.
Most class D amps have floating outputs meaning two amps cannot share one speaker connection.
