Just got an aftermarket HU installed, unfortunately no type of filter.
Do these really work? They are a godsend if they do!

They are crossovers... of course they work.

Awesome, just making sure it wasn't one of those "gimmicks" Like those italian horsepower chips for dodges.

What's interesting is that they don't tell you what ohm speakers it's designed for to get that 400hz crossover point....I assume 4ohm, but they should still specify.

Agreed, Ill find out when they get here if they make a difference, anything is better than buzzing door panels

they also make inline rca ''bass blockers'' as well. 400hz is really no help at all though. What are you going to be running them to I'm guessing mids?

Fix your doors, IMO. With a 400hz crossover you're not going to have much midbass at all, unless you're planning on your sub handling that.

80 Hz High Pass 4 Ohm Crossover 266-456 (http://www.parts-express.com/pe/showdetl.cfm?Partnumber=266-456)

I'd use these, they cost more but you will still get full sound.

If you HPF your mid bass at 400Hz you won't have any mid bass at all. Just mid range and treble. It will sound terribly hollow and lacking.

Should be 400hx @ 4 ohms.....

Don't care for midbass, more a tweeter guy. Just listen to rap mainly. Now if i had the cash for a nice amped setup, it would be different.

Holy hell 400 hz? Some parts of your voice are lower than that.

Fun fact: While speaking you exert frequencies in the single digits.

Rap will sound like extremely bad poetry and a cymbal machine at that HPF. You will even lose some of the vocals with that HPF. An 80Hz bass blocker would be a much better alternative.

Need to find something around 80-100 hz.

Harrison Labs makes some inline RCA crossovers that may be worth a look.

I have not had very good luck with wired in-line bass blockers, but the fail could be related to other cheap componets in the signal chain.

Why not get a better passive crossover?

Also, I agree with other posters about the 400 hz crossover. I'd only look into that for a midrange or something, not a midbass.

Bassblockers are 1st order crossovers at 6 dB/octave. It's not going to "block" must bass if you get one for say 120hz. It will only be 6 dB down at 60hz and 12 down at 30hz.

To be effective at taking away the low end and sparing the speaker, you'd need it to start pretty high. 400hz would be a safe bet.

If you want to keep your midbass, you need to go active most likely, or develop a 3rd or 4th order HP passive crossover. Not too hard to do something like this generically.

If you wanted to get a very rough 80hz 24/db crossover, run two of those Part-Express passives in series. Each one will knock down the lower frequencies by 12db

That's the easiest solution to your problem. I might even do that at 100hz


Edit:

http://www.parts-express.com/pe/showdetl.cfm?Partnumber=266-460 2 of those in series before each speaker would be 24 dB/octave. Would do a lot in eliminating those "rattle frequencies"

I went with 200hz and down should do what i need
