Over the weekend I added two MTX Thunder 5000 10" subs into the car that I brought from Indiana to California (where I live now) in my suitcase. These subs used to be in my 1996 Ford Probe GT. The TSA wanted to keep them because they were potential bludgeoning devices. UGH. I had to buy a new amp, so I got a Hifonics 1000d mono amp... which is actually a really nice amp. It's hard to believe all this bass is coming from 2 10" subs. The original sub is still in there, but not hooked up, and the original amp... well I think it died or something. It wasn't working, and replacing it seems to have fixed the problem. I took it apart but couldn't find any problems.
