They go on the positive wire, between the amplifier/head unit and the speaker. And it does not matter which end goes to which, it'll work either direction. You don't really need a case or anything though you might want to cut off excess wire and just solder them in line with the speaker wire, and then tape up the connection for a good clean look.

Why do you think they are a waste of time? True, as a first-order band filter they only have a 6-dB rolloff, but they do help. I have 180uF caps on my 4s in front and they do just good enough a job to keep them from getting fuzzy at high volumes.

Agreed--they do have their uses. Particularly when you want a simple, inexpensive way to filter out bass from small front speakers to stop them from bottoming out.

I agree, considering bass blockers are just np caps, they work quite well for passive, high freq filters. 22uf is gonna cute those speakers off fairly high im guessing in the 1500-1800HZ range.

Electronic crossovers are only good if you are using multiple external amplifiers, because they only accept RCA inputs, not speaker-level inputs. And their crossed-over outputs are only RCA as well.

If you do have, say, an external 4 channel amp and a 1/2 channel sub amp, but only one set of preamp outputs from the head unit, this is where a crossover really comes in to play as it will let you direct different frequencies to different amps.

Bass blockers are not really intended to be used in the higher-end systems with external amps anyways.

another note to add is Bass-Blockers (A.K.A. Non-polerized electrolytic Capacitor) also don't filter out distortion from the HU output. So distorted signal goes in, distorted signal comes out, minus the lower octaves.

I hope you didn't pay over $5 for those.
