Excuse a noob question but how do you know which is the - and the + on the speakers? On the right hand speaker, looking down at the mobo, the wiring seems to follow the norm i.e. red + black -. I was going to check the voltage before disassembling my PSP but forgot!
ok so i got my lm386 installed i like it because when there is no sound thy are both completely off then when there is sound they react. they are brighter than befor but i find that some songs that are loud and have a lot of background sound make the led just glow at brightest and slightly dim rapidly but i like them better this way i didnt use any resistors just used the power and ground under the speaker port and the + - on the mobo for speaker out put
my blue 603 arent conected to the lm386 because im afraid to fry them and they are hot glued on so they are a to get off without riping all the wires. i have some 10 ohm resistors is that enougf my lm386 is wired to a 5 volt source
id say it makes the psp almost twice as loud
