I am about to build a ported box for two ES300D's and I am wondering what you guys think an ideal box size and tuning would be. Hertz recommends about 2.55 cubic feet @ 30Hz but what do you guys think?
I have a 98 olds intrigue and currently have two Hertz ES300 subs in the trunk in a 2 cubic foot sealed enclosure. I was just curious if you think 4 7kv.2 would be louder than my two hertz subs.
