I'm wondering if a 20hz subsonic filter is too low for a box tuned to 32? I'm thinking of buying a pioneer amp that does 1200@1, 800@2, 500@4. but it has no subsonic filter and ima use my box, sub will be sd-2 12. should i just get a different amp or can i run one of these things and be fine?

24 is the low for 32hz. I had the same 9601 and had to pull it when I went ported.

 
My box is tuned at 30.5 where should I set SS at ? Sub is 18" Fi team and don't mean to hijack thread just thinking about it as I read this .
