I am putting together a comp set consisting of Vifa ring radiators and some Kenwood 6.75" mids I have. I need a set of crossovers for them. I wouldn't mind at all if the crossover was able to be bi-amped. Not sure I'll go that route but would be nice to have that option. They are gonna go under my seat so the do not have to be perfect but I don't want junk either. Let me know what u have. Thanks.
