Great sub. literally had a few hours but impressed. I was led to get a Kicker shallowmount CVT 10". I did - it blew or tore from the frame in a month. So had to listen for the last two months with rattles and air leaks. Just installed this JL Audio 10w1v2-4. WOW!!!... definitely more bass than the kicker when it was working... smoother and richer and this 10 i have in my little cheesy ground shaker under my rear seat of my 05 F150 is making my mirror rattle.. the other did not.. It is strong and seems to pack 2x more punch.. i ordered a second one because I was so impressed. Running it off a pioneer 6300 radio w/ kenwood 8105 mono amp.. worth the investment..
