[QUOTE="Art Welter, post: 212756, member: 52"] Adam, For a single element passive crossover you should use an inductor (coil) in series with the woofer, the issue you have is likely driving a power signal into a short at high frequencies, as the capacitor in parallel with the speaker will shunt the current via the cap, and so it will tend to short out both the amp and speaker. It is far preferable to use filtering before the subwoofer input, as passive components for the subwoofer range are large, expensive, and waste power, and are difficult to design due to the speaker's impedance covering a very wide range, depending on frequency. The output transistor(s) or other components in the amp may have burnt, replacing the bad components could fix the amp, but don't repeat the mistake. [/QUOTE]
