I'm looking to appropriately size and wind a transformer to swap speakers in my car. Its a project to keep the factory amp and see what kind of performance I can extract from it as a challenge instead of just dropping in a nice aftermarket piece.
I need a core that can handle two primaries feeding one secondary with each a ratio of 2:1 and handle transmission of about 40W peak during transients.
The two primaries are to make use of the OEM amp that is designed to drive a dual-voice coil OEM sub and then hook the single secondary to an 8 ohm sub.
So how do I size the core (and find a source for it that's pretty cheap) and then figure how many turns of what minimum gauge wire I'll need to do this without over saturating the core? Bandwidth is maybe 30Hz-100Hz so that should keep the inductance within reason but I have no idea what numbers and sources to use.
Thanks in advance.
