First I have to say shipping was way faster than I thought it would be. Ordered on Thursday afternoon sub arrived the following Monday. Sub performs very well for a shallow 10” I am very limited on space in the vehicle it was installed in. Used the current box I had which was a JL audio bass wedge. Had to enlarge the diameter of the hole for the sub quite a bit which was to be expected since the dd a lot beefier then the JL 10” that came in the box. Powered it with an alpine 500w mono amp and man this thing bumps. Very happy with my decision on going with the dd audio over others I was considering. I’m very pleased with the ordering process and shipping from big Jeff audio also.
