Will Polyfill Help?

[fouge642]

Hi,

I don't have too much money so I am wondering if polyfill will help.

I have a kicker L7 12" (4ohm DVC wired in parallel for 2ohm load) running off of a Kicker ZX750.1. It's a great setup but with my box it sounds horrible. I have a groundshaker ported box like this (tuned to 34 Hz) and it is too small (1.32 cu ft.). According to Kicker I should want a 1.75 cu ft. box minimum or 3.25 cu ft max.

This video by soniceletronics has the same setup

. I get a lot of port noise at certain frequencies and on certain songs when the kick drum hits too hard (electrohouse music). On other frequencies like when the bass hits in this song it sounds PERFECT.
If it helps how much should I stuff in it?

And my bass is not to strong at higher frequencies. Would polyfill help lower the volume of my low frequencies so I could get more even bass and then just turn up my gain?
