I need a crossover
 

so that i can hook up my sub, the headunit has not sub-preout. what do you guys reccommend for good ones. i've had my eye on the sony XEC 1000 and XEC 700

if you don't have the amp/s yet.. get one with a built-in crossover.
If you do.. Audio Control makes good xovers

Phoenix Gold. :D

I've got an EQ-213 (older model '96) and has held up very well. 2 channel 13 band (I can't remember the slope) Might be a little pricey though.....
