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.

elc crossover is the only way to go. passives cut power.

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. ------------- The FLUKE Guy.
