| Market Reality | This is the amplifier family inside nearly every aftermarket car radio: TDA7388 (bipolar, 4x26W class) as the baseline and TDA7850 (MOSFET output, 4x50W class, 2-ohm capable) as the famous upgrade - both in the same Flexiwatt25 body with a real price gap between the BOM lines, and that gap is exactly why relabeled 7388 dies sold as 7850 are the classic fake of the car-audio scene. The upgrade is welcomed by an entire community of head-unit modders, which also means the swap has published caveats - input network changes and the pin-25 discrepancy - that the datasheet alone does not spell out. | - |
