    I'm new need help

    A Schematic is just like a Road Map. It showes you where and how each component is connected. Each comnponent has a symbol that represents it, Some of them have values assigned to them. If you learn what each component is and what it does you can read a Schematic or Circuit Diagram. It takes...

    Dual LM3886 Bridged Amp.

    What formula are you using to figure the db difference between 30 watts and 50 watts. I figure that 50 watts PEAK is about 35 watts RMS. So 50 watts RMS would be about 70 watts PEAK. Now lets do the same with 30 watts RMS. 30 watts RMS is about 42 watts PEAK. So if we look at RMS we have a 20...

    Dual LM3886 Bridged Amp.

    If the speaker is not in a box that was designed for the specs of the speaker it will not produce optimum sound or decibels. If you just buy a box off of the shelf and speakers off of the shelf they probably don't match. You need someone to do a test on the box to see what frequency it is tuned...

    Dual LM3886 Bridged Amp.

    I think there is alot of difference between 30 watts and 50 watts. That is almost double! You can tell the difference between 5 watts and 20 watts so you can hear a big difference between 30 and 50 watts. The distortion of the amp is not the only concern when Bridging amps. They tend to run...

    Dual LM3886 Bridged Amp.

    I think Bridging amplifiers causes distortion. You have a cleaner sound when you use them with 2 speakers instead of bridging them. The supply voltage for optimum would be a +/- supply of 28 volts . A Dual supply. Look at the charts in the Datasheet Attached. LM3886.pdf
