Got the SSD's installed today. Not a HUGE difference over the type r's but they do hit harder. I still need to do some tweeking on my amp. Seems as though the subs are bottoming out. Gain is only about 1/4 turn up on the amp. But still I would say it hits harder than the type r's and the JL's at this point. It took about 10 days total to recieve the subs once I ordered. They would have been here a few day sooner but I noticed on the tracking that they got held up in Cali for some reason. I also thought that was weird, they went from NV to CA then to TX??? Oh well, no complaits here, these subs ROCK!! where did you mount your amp, i have the same truck and im lookin at the same box...just wondering
