I have a 1250W in my car since 2009, i love that sub, for the price it were sold back in the days, was a steal deal. plus the looks of it are KILLA'
I installed a 1214 in a friends car with somewhat same setup as mine, and it was a good subwoofer as well; all these, 1262, jbl 1214 are good subwoofers. I would advise to get any one of these, save up a bit and increase the budget for the mono by 5-6k and get a good mono once and for all.
Available for that price in KHI? Pakar lou, because from what i've heard shopkeepers are asking above 20 for that sub. That sub can go low, the lower extension on that sub is very smooth, beauty!
