You could try stuffing your enclosure to the gills with Polyfil, but I still think the high tuning will work against you. When I say stuff, I mean stuff as in you will have to push your woofer into the enclosure to screw it down!It's an extended cab pickup but yes, you're right. Do people who tune their boxes to 40hz enjoy this sound? When I first heard it, I wondered why there was such a big following behind dd. I was very disappointed. Im hoping and praying it's just a box problem. I guess my only choice is to have another box built. I've been bass less for about 3 months now and it looks like its not getting any better.
Is there anything else I can do??
