Will these bass blockers do the job?

[nismos14 5,000+ posts]

Hey,
I have some Pioneer TS-A6962R 6x9s installed in my car. They run straight from my HU and I'm afraid of blowing them when cranking the sound up. I was thinking of getting some bass blockers so that the low frequencies don't blow them and I can really crank up my sub.

I was wondering if these will do the trick:

They seem to be good, and they are cheap. Will those work? Its for 4 Ohms so it will cut off 300Hz down, is that good for 6x9s or should I get like 800Hz down?

thanks

Are you running an aftermarket head unit? You should REALLY amp those speakers to get hte best out of them.
