I have a set of A/D/S 346cs 6.5 components and an Audison LRx4.300 4 channel. The audison has two sets of crossovers. The front two channels have a hi-pass crossover and the rear two channels have a low-pass crossover. Is this all I need to run it active? IE run tweeters to front hi pass and woofers to rear low-pass?
