are there other wire pairs that you ran on the same route that were intended for other speakers that you might swap to the woofer to see if they are any better?

Would it work to use the amplified output from the audio amp and put it through a potentiometer/volume control/attenuator. Whatever you call it you could maybe adjust the signal high enough to compete with the noise but not so powerful as to harm the amp in the sub-woofer?
Or shunt the cap to an AC outlet to clip the buzz?drvnbysound said:Capacitors become a short at high frequencies, so they will pass the high-freq. Inductors are what you'd be looking for.
There are bunch of online resources for using components to build your own crossover networks; I used to frequent www.the12volt.com a lot. They still have all of the information there, but I don't think the site has gotten an update in quite a while now.
