what is the difference in sq and spl when putting a sub that calls for 3-6 ft ported enclosure in an eclosure only 2.5ft ported.will it hit harder or not ,will the sq be better or worse and will it change the amount of amperage it can handle being in a smaller box.thanks
SPL will be higher in the larger box, and SQ will be better IF the sub requires that large of a box. If you go with too small of a box for the sub, then the frequency response will be peaky.
