A:AnswerMike morning. Those are filters so your Speakers don’t make a crackling noise.Big ones are for larger Speakers and small ones are for small Speakers . Cut old Speaker out connect filter to cut wire Positive side and connect other side to Positive wire on speaker. Just need one per Speaker. Use small blue wire nuts.Best Buy Audio can give you a diagram for you to use. Black is Positive,White is Neutral.
A:AnswerThe back of the package shows these values:
300 Hz cutoff for the 133uF caps at 4 ohms
2800 Hz cutoff for the 14uF caps at 4 ohms
The formula for calculating cutoff is...
C = 1 / (6.283*R*F), where R = impedance and fc = cutoff frequency.
A:AnswerI’m not positive but I think the 133 uf would be better for a 61/2 inch speaker … it would just make sense that would be what you use and I am asking for the same thing just I have 51/4s and I wanna know if I use the 133 or the 14
A:AnswerIt blocks electrical frequency. So for a speaker that hits highs and top ends you would want this. It goes between your speaker connection and your cars speaker wire.
