Bass Blockers Won’t Work

No its not like that, i have 2 kenwood 6969s in the back.(60 WATTS RMS with no amplifier on them)).now without the bass blockers i can turn the speakers all they way up (50/50) with the bass all the way to max, and they work great, you just cant  hear the actual music cuz theres so much bass., thats why i wanted bass blockers.now when i attach the bass blockers, THATS when they start getting all choppy and scratchy when i turn the HU volume up to about halfway (24/50), even with the bass all the way down... The speakers are fine its just that something about the bass blockers is making the speakers mess up, or the HU clip, or whatevers happening..i just wanted them until i hook my real amp to my sub and hook the 4 channel to my speakers thats all, i just want to know why it sound like that (ONLY WHEN THE BASS BLOCKERS ARE ON)

SORRY IF I DIDN'T EXPLAIN MYSELF COMPLETELY THE FIRST TIME.

did you hook up the capacitors (bass blockers) in line with the positive wire?

The other thing that happens, when you install something like that is that it makes the impedence change. Often you read about 2 ohm and 4 ohm loads, and you realize that 4 ohms is easier on the amplifier. Some ampilfiers actually like the heavier load, and putting the capacitors on causes the amplifiers to become unstable. My suggestion would be to try something simple like a 10 ohm resistor in parallel with the resistor. I dont think that you are exceeding the voltage rating of the caps. I have built home speakers for use on 100WPC amps using only tiny 35V caps without any major problems.

GOod luck!

I meant  put the resistor in parallel with the capacitor. Sorry about that.  The 10 ohm resistor should still help keep out most of the bottom end.

the resistor is intended to put a load on the amplifier, and thats it. if the speaker is 4 ohms, and a resistor in series with it is 10 ohms, the resistive load would be approximately 14 ohms. That would stabalize the amp. if the bass blocker is a small value (high crossover point)  putting it in series with a 4 ohm speaker could cuase the impedence to change drastically think about it. if you put two 4 ohm subs in parallel with each other. you get two ohms, right?  But a woofer and a tweeter together in parallel would still be 4 ohms even if each is 4 ohms. that is becuase the capacitor used to cross the tweeter over raises the impdence up to the point that the amp doesnt even notice its there.   So by putting a resistor in parallel with the bass blocker, and then running that network in series with the speaker, it returns somewhat of a load to the amp, which will stabalize it.   I would bet almost anything that a lack of load on the amp is the problem. Its just like how you need SOME back pressure on your exhaust.   And as for changing the frequencies, the resistor is most definately going to change the slope of the filter. It will be less steep, I dont feel like doing the math, but since a cap by itself is 6dB/Octave, we can assume it would change the slope to around 3dB or so..  This isnt really a great thing, in fact it would be best if it didnt happen, but it will still cut out a fair amount of the deep bottom end thats causing the speakers to woof too much.

Good luck. I promise that my info is correct.
