What info you need? Car is a Scion tC and it will be going under the hatch. Set up is currently Eclipse CD-5000 deck, Stock front speakers (crossed over from HU), Elemental Designs Nine.2 amp, and the blown Kenwood sub. I am planning on building a new box based on whatever sub I choose. I just want a sub that will provide good SQ to fill the lows, as I listen to rap/hip hop. Obviously SPL isn't my focus or Id just get a new amp and sub combo, but I just do not want to spend that kind of cash. My price range for the sub is $200-$250 max. I may decide to upgrade the door speakers eventually, but I had been pretty happy with my previous (budget) set up. Since the woofer blew, I need to replace it and want to be sure I get the most bang with my current power. The IA LI looks great, but is a 600 watt sub, how would it perform off my 400 watt amp? The FI SSD is an 800 watt sub, so it would be severely underpowered. Again Thanks for any help that you provide!
