Most of us are powering this amplifier with 12 volts, still it offers 30 watts per channel @ 4 ohm. What is the main point to limit gain getting amplifier as down as 3 watts ?
@@Thirteen.. . To make the amplifier suitable to small bluetooth speaker with pair of 3,5,10 or 15 watts speaker whatever... for me if you want to achieve clear output in your diy bluetooth speaker set up is. Instead of matching your amplifier in your speaker. and your speaker used the whole potential of your amplifier output, its hard to tune it by increasing the voltage and current. Sometimes its failed because of heat issue. Thats the disadvantage of matching the amplifier in your speaker. But if i use amplifier with higher wattage than my speaker the Distorted sound and heating issue is not a problem anymore. The only problem is over drive on my drivers. Now i put trimmer pot and trim the sound depends on my speaker can handle. Now the distortion,heating issues ,over drive and current fluctuations is solved. The disadvantage is the higher wattage amplifier is much expensive Instead of buying exact wattage Distorted amplifier to my low wattage speakers and stressed about Distorted sound at max volume. Thats my point incase someone find solution on youtube about that. I hope you understand this long explanation for you my friend and the important i want to said to you is you're not the market of this video. Sorry to bother you my friend here on youtube. If you want to use same amplifier and speaker. Then go. Thank you😊
The 6 pin pot he removed : First two points at the edge : : : are input from bt, aux etc. Next two are output towards ic. You will need to use suitable resistors for summing the channels.
@@DiyataParesOvercook44 need pa din po. Kaya pa rin wasakin ng 502 Mt Ang 15Wx2 Lalo na kung naka ported ka at Hindi naka passive radiator. Pero kung naka passive radiator po kayo ok lang kahit Hindi na wag lang Iwan sa malikot na Bata at baka isagad Ang volume at maginit ng sobra Lalo na Yung 15W na LG 3"
Don't do this mod. Use 15w 8ohm. In case you already have a pair of 15w 4ohm speakers (full range or woofer) then add 4 ohm tweeters in series. The minimum suitable size of speakers should be 4 inches for this amplifier. Additionally you can power this amp with 9 volts to reduce output power.

Sir nasaan dyan ang left and right audio signal ni 502mt? Plano ko kasi gawing mono signal sya pero 2 channel pa rin.

Oops ! You can sum channels out of board if using Aux. And in case of phone bluetooth you can transmit mono signals from your phone settings.
Follow what mr thirteen's said.
Okay lang ba di na gawin yang mod nayan kahit 2x 15w speaker lang ang ikabit ko sa 502mt.

Patyung katulad kong sayo speaker madaling masira sa bandang may ruber😢
@@happykids5030 pangit talaga yan. Mabilis mapunit
A cheap shot….speakers should be matched to power amp output…Simple…
Thanks for commenting : )
