Hi,
I am attempting to construct my first speaker and have a few very ignorant questions:
1.) What input types are allowed for the Lin and Rin inputs labeled in the schematic below? Would I simply use an auxiliary cord connection for both (ie connecting to an iPod/similar mp3 device?)
2.) Would the speakers be connected in series at the Rout and Lout connection points?
Here is the schematic:https://cdn.instructables.com/ORIG/FVB/RX3D/GY65QG9K/FVBRX3DGY65QG9K.jpg
Here is the TDA 1542 spec sheet:
TDA1524A Datasheet (click technical spec sheet on the product page)
Thank you in advance for the help!

Appreciate the help, would an amplifier then connect to the output? Would the input be an auxiliary connection from iPod/like device?
Thanks

You can ofcourse connect an amp to the preamp but most amplifiers have enough gain for an ipod to be used without any preamp between them.
You can connect the inputs any way you want. I've used alligator clips a lot. The wretched RCA is the hi-fi standard. XLRs work better but are overkill for small audio. Stereophone plugs/jacks won't stand hard use but are fine for home use, and natural if you live on iPod.
That chip is a volume+tone control. To drive a loudspeaker you add a Power Amp after it.

Thank you all for the help, what type of amplifier would be best for this application? Can you give an example of a part number that you would suggest?
You could combine it with almost all amplifier boards. That depends on your speakers, deeded volume (=power) and your power source and speaker concept (Mono, Stereo, 2.1?). You should use a single-rail/single-voltage amplifier to make the power part much easier to realize.
A TDA7492 or TPA3116 would be a good choice if the battery has 12V (or more), for 5V a PAM8403 works fine.

Sorry I should have mentioned my speakers, I have two Dayton DA135-B speakers and two Tang Band W2-800SL speakers. Does this change your amp recommendation?
Dayton:

Tang Band:

Well, yes. The PAM8403 doesn't have adequate power and works a lot better with 4 Ohm, same for other 5V amps. The TDA7492 and TPA3116 are fine, the TDA8932 is a good option too (and extremely cheap). You can go for 12V or 18V (a lot more power).
Hey I am having issues wiring the control circuit, I bought several RAC cables, stripped them, and tried splitting them appropriately at the input and output but cannot get it to work. If I am trying to plug the aux cable into an ipod or iphone, what cable should I purchase to effectively split the signal to both the right and left input? What cable should I purchase to split the left and right outputs to the amplifier specified above?
Thanks in advance!
Thanks in advance!
