Great subs all around. I'm pretty open that i'm a car audiophile so when people have questions about products i always direct them to either Crossfire, JL or Boston Acoustics. Depending on budget and what they are looking for sound wise the list goes on and on. The Crossfire C5's are absolutely amazing. The SQ is there as well as SPL. Whether your looking into a sealed or ported. The RMS is only 300 and the sensitivity is pretty solid so dont be scared to power these with a 400-500 watt rms amp. They Pound, Slap, and Bang. If your an everyday driver and like it loud n clean buy a pair. You'll be glad you did. As always Sonix is very good on shipping and priceing so stop looking and thinking just BUY :-)
