Forum @hasan is applied to a beautiful project that share our members apply the tested also be shared on the blog for a project that would be good.
Car amplifier 3 main parts SG3525 ( ka3525 , kia3525 , uc3525 are the same) PWM control based on the SMPS circuit ( EI35 Transformer ) BJT transistor amplifier circuit and the original JBL filter circuit for sharing @hasan Thank you my brother following remarks are his own .
At the request of a friend of my car I would like to present to you amp circuit .
250w RMS Aplifier circuit + JBL active filters include SG3525 DC to DC SMPS .. Ei33 Ei35 have used instead .. SMPS volts at the maximum number of zener diode voltage if you want to insert it . 75 volt zener diode installed in mine . +75 / -75 Volt have achieved ..
Coolers are on trial for … I tested the amp at 2 ohms . Vurdukça bass sounds like it came from the power supply source 🙂 JBL filter made very good gains . Circuit worked the first time without showing any problems .
