Hi! I was looking into building an amp from the LM3876 power amp chip. I am just looking to find somthing to drive a set of subs in my car, or even just play with. I figured that the IC might be a little easier to work with than the FET family of transistors.
I planned on running one amp and one sub on the left channel of my preamp out, and one amp and one sub on my right channel of the preamp out. My subs aren't that big wattage wize, so I figured that the 40 or 50W would be good.
There is still one problem. The schematic on the ESP site that I might like to use calls for like +/- 35 volts, and my car has +12. could I run the amp on 12 volts? or would it be possible for a voltage regulator to boost the voltage up to 35V? I am out of ideas. My electronics teacher said that it would be best to build an inverter, run it thru a transformer, then rectify it to get the desired voltage. Would this really be the easiest way?
Whell, Thankyou in advance for the help!
