Why do you want to do this thing ? There are ton's of reasons why you shouldn't, so this is why i ask...

If you check with Audio Control the maker of the EPI, I think you will find they have a built in SUBSONIC filter which will render your activities pretty much mute and useless by filter cancellation of anything in this range of frequency's.. So unless you undo their protective Subsonic filter that is built in, I think you might just be wasting your time trying to do this mod.... Just thinking out loud here and not picking on you or anything...

i am talking about the frequency chips, they put in side the are made up of just resistors the lowest audio control have is about 20hz the 35hz is made up of 22oK resistors so with highe rvalue resistors the frequency will get lower i just want the exact value

7200 divided by the frequency you have in mind = the resistance in Kilo-ohms

here is the link:
Mobile Audio Support

and this manual has their math in the bottom of the page second row of lit:

And here it is again on page 20 of this manual:
