Hello,
My car currently has no stereo, so in lieu of buying a stereo, I'd like to build an amplifier circuit to connect my MP3 player to my car's speakers.
The obvious problem is that I don't know how!
I am very new (about two months or so) to circuit design and building. I know my basics (Ohm's laws, EIR, PIE equations, etc.) and understand the basic concept of a transistor amplifier. Beyond that, I'm a bit fuzzy.
I have perused around and using a MOSFET IC (such as one of the TDA series ICs) sounds like a good way to go, and I have once stumbled upon a 4 channel IC somewhere (don't remember where, though!). I've looked at many schematics, and have gotten a vague clue how to go about it, but I still don't understand enough to design my own circuit, or even really to use one of the ones I've come across. As I understand it, a car provides 12VDC, but many of the schematics call for 20VDC and up.
I realize my query is a bit open ended, but any help is appreciated, and as my research into this continues, my questions will become more focused.
Thanks!
Stuart
