High-pass filter. Yes or No?

I'm going with the Infinity Reference 6000cs Component set for up-front.
And the Infinity Reference 6002i 2-Way Speaker for the rear...

Now, the Component set comes with a X-over... but the rears dont.

Do I need to add a X-over to just the rears, or add then to both the Front and rears?

And, would it be beter if I made the X-over myself or where would I find them to buy?

BTW, I've got 2 Shiva's powered by the bp600.1 in the hatch.

Thanks all!

In my opinion you should put a high pass filter on the midrange speakers if you have a subwoofer handling the lows.  The component crossover handles the cross between the midrange and the tweeter, but does not put a high pass filter on the midrange.  Without a high-pass filter there's a good chance they'll bottom out when the music is loud and low, causing audible distortion and potentially harming your speakers.  Most new head units come with some sort of built-in electronic crossover.  Does your deck have this feature?  If so, I'd recommend using it.  Are you going to put these new speakers on an amplifier?  If so, most new amplifiers also have some sort of high pass cross feature.

OR you can use a passive crossover, building your own or buying them for a cheap price.

they will all be powered by the HU...

looking at the Crutchfield like you gave, I've got 2 of them (which i found lastnight) how do i test them to see what HZ they block?


Also, what HZ do you suggest to block?
I usually have my subs upto 120HZ

150hz should be fine for a 6.5" driver.

GOTCHA... thanks for the help!

Just a side note: you don't have to set your sub amplifiers crossover at around 110 to 120 hz, because those bass blockers only provide a 6 db/octave slope rate so, the lower bass frequencies are gradually rolled off.
